WFA-PF generates water from air

WFA-PF generates water from air

The WFA-PF electrostatic air filter effectively prevents micro-particles and dust from entering the appliance.

The WFA-PF the stainless steel public fountain generates water from the air. We generate pure drinking water from the air.

The powerful fan takes in a large amount of air and to minimize the intake of all the impurities, the WFA=PF pulls air through an electrostatic filter removing 93% off all air particles.

WFA-PF material

Body, tray and tanks manufactured from Grade 304 (18/10) Stainless steel, hygienic and vandal resistant.The WFA-PF is designed to provide drinking water in public places like schools, rest-areas, playgrounds, parks, museums, universities, malls, airports … The high tech filtration system purifies the water to ensure an unsurpassed quality independently of geography, air pollution and climate conditions.

 

Electrostatic air filter

The condensation unit receives the clean humid airflow. The condenser coils are covered with a food grade coating, to minimize interaction between water and the metals using for the cooling coils. Using these coils, allows the water to condense from a vapor into a liquid.

Aquaflow WT Kolk stows more water at low cost

Stow more water at low cost

Heavy rainfall?

Street flooding that occurred during Hurricanes could become more common in the decades ahead. This Aquaflow solution helps cities keeping the streets dry.

In the first statewide climate change outlook for New York, scientists say that the state may suffer disproportionate effects in coming decades compared with other regions, due to its geography and geology.

The report paints a harsh picture, including possible extreme temperature and sea-level rises, downpours, droughts and floods. The changes are projected to affect nearly every region and facet of the economy by the 2080s, from ski resorts and dairy farms to New York City’s subways, streets and businesses.

Stow more water at low cost

This water stow solution avoids the overflow of the streets in your city.

Aquaflow WT kolk video

Global warming is not evenly distributed; because of its northerly latitude, New York has already warmed 2.4 degrees Fahrenheit in the last 40 years. More than twice the global average. The report projects a further 1.5 to 3-degree rise by the 2020s; 3 to 5.5 degrees by the 2050s; and 4 to 9 degrees by the 2080s. Winters will be milder, and summers will see more extreme heat waves and droughts, say the researchers.

3Di floods: avoid disaster management during a flood

3Di floods: avoid disaster management during a flood

During the calculation, the user can retrieve information and make changes. These modification may relate to the spatial planning or the water and wastewater systems and civil engineering structures.

2D models of rivers and estuaries have been around for a long time, but they are too slow or too large for many applications. Putting the outer flood fields underwater or draining them again. 3Di shows the affects in case of flooding, dry periods, water transport by the river etc. All described exceptionally well in a 3Di area model. The answer to ‘What If’.

The 3Di area model also allows the effects of deeper dredging, harbour expansions and bypasses to be examined. The effects of nature development in the flood fields or the utilisation of overflow areas can be made clear to everyone.

USA analysed

3Di has been used abroad to make 2D models of Jamaica Bay in New York and San Francisco Bay. The calculation time for these models is just a few minutes, although the models contain a billion cells.

Creating an area model

The area models are generated automatically from the object database and the raster database by a 3Di specialist. The object database and the area models are stored in the cloud. All the variants of an area model are managed automatically in the cloud and it is possible to retrieve older variants.

Interactive

When a calculation is to be carried out, the user has a 3Di web interface for choosing an area model and a scenario. The user can start up a calculation with the ‘play’ button and follow the calculation on the map as it progresses. During the calculation, the user can retrieve information and make changes. These modification may relate to the spatial planning or the water and wastewater systems and civil engineering structures.

Diatom Algae based Sewage Treatment cleans rivers and lakes

Generally waterbodies contain more of nutrients, N and P, and less of micro nutrients, since metals are not stable in water. So by providing the missing micro nutrients, diatom growth is enhanced.

Generally waterbodies contain more of nutrients, N and P, and less of micro nutrients, since metals are not stable in water. So by providing the missing micro nutrients, diatom growth is enhanced.

While the drought continues in large parts of the world. We need to reuse all our water. Including water from the industry an agriculture.

But what if this water is polluting rivers and lakes?

Well this biological Diatom Algae based Sewage Treatment is the most sustainable sewage treatment solution for lakes and rivers  worldwide.

It is not at all common to reuse treated sewage. Worldwide only a very small quantity of treated sewage is reused. The current treatment processes are not targeted at reuse of treated sewage. The treatment is only to enable discharge into large waterbodies.

Removing nutrients from large waterways

Removing nutrients from large waterways is not being practiced at present. The challenge is to treat wastewater fully at a lower cost. And that’s why we promote Diatom Algae. 

Diatom Algae cleans ALL water in the world of nutrient ( N and P ) pollutants

  • Nualgi is dissolved into the water and this causes a bloom of Diatom Algae within minutes.
  • Bubbles of oxygen released by the Diatoms can be clearly seen, this starts within minutes and continues for upto 2 weeks.
  • This oxygen is available to Aerobic Bacteria and these breakdown the organic matter in the water.
  • Diatoms are consumed by Zooplankton and these by fish.
  • Thus Nualgi results in the remediation of the lake and in increasing fish yield.
  • The Blue Green algae in the lake can be seen crashing out in 2 hours of the use of Nualgi, this floats up and the lake appears dirtier than it was at the begining, but this is just part of the cleaning up process.
  • And it’s cheap comparing with other treatment processes.

Everyone is spending money on collecting sewage, treating it and then disposing off the treated sewage into lakes, rivers and oceans. When it is disposed off into lakes and rivers, it gets reused indirectly but when discharged into oceans the fresh water is wasted.

Don’t spill a drop of water, collect rainwater

water storage capacity needs to be increased

water storage capacity needs to be increased

Aquaflow ‘RoofWater’ collects rainwater and stormwater from the roof of office buildings, parking garages and the courtyard.

The water is directed to the filtration system and storage cistern located in the underground of the building. Collected and filtered water is then stored so it can be reused. 

Rainwater

Rainwater on the roof must be quickly passed to the underlying storage; that’s why we use high demands on the pavement. This system is finished with special water passing or water permeable bricks.

These stones can dispose up to 4,500 liters of water per m2. Per hour a capacity 20 times higher than the norm!

Rainwater harvesting infrastructure

Water shortage India

3.5 million people in Delhi have shortage of clean drinking water

Does your city has shortage of water? And do you want to collect all the water that comes in? Is your space precious? With this Aquaflow® system your city collects rainwater in roads, transports it to the recycle plant so you don’t have to spill any drop of it. 

 

Watch the video

The space for rainwater storage arises because the road foundation is built with multiple broken stone with 40% voids. The salvage deflates by infiltration (on sandy soils) or delayed drainage to avoid that the ground drops down because of lowering ground water levels. Multifunctional land at its best: ditches and ponds disappearing under roads and parking lots.

Aquaflow offers cities their knowledge and experience. They give advice about the best infrastructure to collect the water for your city.

  • Works can be done by local contractors.
  • The pavement will be made in your country by a local company.

Water from roofs and streets

Climate change, rainwater storage, water reuse, infrastructure in cities

Aquaflow water harvesting combination with asfalt and tarmac, especially for roads and garages

The rainwater from roofs as well as from streets fits into the road foundation. The water from the street usually drops off by water passing or porous pavement.

But it can also be through a special AquaFlow WT swirling or Aquaflow water trip in the gutter with asphalt, tile or solid paving. Water from roofs can be connected above the ground or underground.

Recollect water on roofs

A multifunctional roof, such as a square on the roof of a parking garage, can be used to buffer water. For this purpose the Aquaflow system adapted to the demands of a roof: waterproof, low height and lightweight.

Properties

  • buffering and storage of rainwater
  • purification and capture of pollutants
    • heavy metals
    • hydrocarbons
  • slow drains or filters
  • complete design freedom
  • utilization of rainwater
    • usage of toilets
    • hydrate gardens
  • high quality of materials and construction

Maesland barrier Rotterdam keeps the water outside

water barrier, floods, climate change, sustainable, infra, green city

The colossal barrier is almost as long as the Eiffel Tower

Virtual tour of the Maeslant Barrier in the New Waterway, near Rotterdam. Opened on May 10th 1997 by Queen Beatrix, the barrier consists of two large hollow steel doors. Under normal conditions the doors are open, concealed within docks on each side of the waterway. This allows unhindered access for shipping traffic into the port of Rotterdam.

When the water level rises to 3 meters above Amsterdam ordnance zero, the docks are flooded and the doors begin to float. They are driven into the waterway and then flooded, thus sinking and sealing off the 360 meters wide waterway.

Construction of the Maeslant Barrier

The construction of the barrier started in 1991. First the dry docks were constructed on both shores and a sill was constructed at the bottom of the Nieuwe Waterweg. Then the two 22-meter high and 210- meter long steel gates were built. After this, 237-meter long steel trusses were welded to the gates.

Standing upright, these arms would be as high as the Eiffel Tower, and each one weighs almost as much at 6,800 tonnes.

The main purpose of the arms is transmitting the immense forces, exerted on the gates while closed, to one single joint at the rear of each gate. During the closing or opening process, this ball shaped joint gives the gate the opportunity to move freely under the influences of water, wind and waves.

Ball-shaped joint

It acts like a ball and socket joint, such as in the human shoulder or hip. The joints were made in the Czech republic at Škoda Works. The ball-shaped joint is the largest in the world, with a diameter of 10 meters, and weighing 680 tonnes.

The construction of the barrier costed 450 million euro. The total Europoortkering-project had cost 660 million euros.

Mudtrap: Circular soil water management

The Mudtrap collects and disposes mud

The Mudtrap collects and disposes mud including the bound phosphates by dredging

The Mudtrap is a circular water (soil) management solution because it collects and disposes mud including the bound phosphates by dredging. 

Do you need to clear the water from a thick sludge layer that adversely affects water quality and quantity? Then use the Mudtrap.

Dredging is necessary due to the continuous accumulation of sludge waste, plant debris, leaves, soil, and other fragments. This settles on the bottom of rivers, lakes and ditches and will eventually result in hinder water drainage.

Mudtrap Dredging

It is important that the sludge is removed. It’s common to remove the sludge every 8 to 10 years. Traditionally, by crane or slider boat. But this method has a negative effect on the ecology of the water.

To sustainably improve the quality of the water MH Waterzaken developed the Mudtrap®. Using the Mudtrap means that the sediment remains in the desired state, and it avoids damage to flora and fauna by traditional soil water.

With Ecobeach tubes Dutch beaches grow significant

bam ecobeach

Ecobeach sand supply on the beach

Ecobeach saves billions of euro’s.

Annually the Netherlands sand supply about twelve million cubic meters to maintain the coastline.

This costs the society millions of euro’s, and this will only increase in the future.

Ecobeach is a positive tested alternative. In four years in test areas at Egmond at Sea, the tubes proved a beach grow by 150,000 cubic meters of sand.

Ecobeach

Ecobeach tubes ensures natural silting making the beach wider and drier. In test sections in the longitudinal direction for approximately 100 meters installed 10 vertical drainage pipes in the sea direction about 10 meters apart. These tubes remain about 25 inches below the surface.

Highest level ever

The trial started in October 2006 and lasted four years. In total there are more than 600 drainage tubes. In late February 2011, the drainage tubes removed and showed the amount of sand on the beach at the highest level ever recorded. (In 1965, the annual coastal measurements started).

Storm barrier Ramspol protects Holland again

Due to persisting winds with forces eight to nine Beaufort on Jan 06, 2012 it was decided to inflate the storm surge barrier at Ramspol. 

The process was started shortly midnight. It took about one hour before the enormous barrier was fully inflated thus protecting the Ramspol-diep for high water in the Dutch IJsselmeer.

April 2015, the barrier had to be closed for hours because of the storm.Closing ‘the gate’ was very successful.

3 inflatable dams

During recent weeks in the major rivers changed from extremely low to very high everal had been flooded. The rapidly rising water level were caused by continuous rainfall especially in the German basin and saturated land, preventing rainwater penetrate into the soil. The barrier consists of three inflatable, nylon-reinforced rubber dams, each 75 m long, 13 m wide and with a design height of 8.35 m. They are the largest dams of their kind ever built. The dam is inflated with air while a gravity-feed system allows water to flow in. The barrier is lowered again by pumping out the water and letting out the air.

The storm surge barrier near Ramspol, designed and built by the Royal BAM Group nv, was built to project the hinterland against flooding by high water from the IJsselmeer lake. It was commissioned end 2002.

XBlocs prevent harbours

xblocksXBlocs are the most economical single layer armor unit. The average concrete saving yielded by incorporation of Xbloc units is up to 15% compared to other single layer armor units.

Casting and placing the Xbloc unit is straightforward and is very cost effective. Xbloc has been applied on shore protections and breakwaters all over the world already for a decade and has proven to perform outstanding.

XBlocs eco and safety

In addition Xbloc has proven to be very ecofriendly as the random structure and high porosity of an Xbloc armour layer provide a good habitat for different kinds of marine vegetation and animals.

  • Xbloc continues to be innovative as the toe unit Xbase and Eco Xbloc show.
  • The special toe unit Xbase has been developed for use with Xbloc armour.
  • On the Eco Xbloc the concrete surface texture can be adjusted to stimulate marine growth and improve the ecological value of the armour unit.

Excellent hydraulic stability

  • For concept design a Kd value [stability coefficient in the Hudson formula] of 16 [trunk section] and 13 [head section] should be applied;
  • The stability coefficient of the Xbloc is the same for breaking and non-breaking waves;
  • Xbloc has a safety margin of at least 20 % without damage to the armour layer. See also: Hydraulic Performance of Xbloc Armour Units.

Automatic interlocking

  • Xbloc units naturally find a stable position on the slope;
  • Self repairing of the Xbloc armour layer after damage is enhanced by automatic interlocking;
  • The Xbloc unit is simple to place, due to the straightforward placement principle.

Low wave overtopping

  • The highly porous armour layer minimizes wave overtopping. For more information see: CLASH test results: Overtopping performance of different armour units for rubble mound breakwaters;
  • For guidance on overtopping coefficients see: Overtopping and Wave reflection.

Low wave reflection

  • The highly porous armour layer minimizes wave reflection:
    Wave reflection from coastal structures by B. Zanuttigh and J.W. van der Meer;
  • For guidance on reflection coefficients see: Overtopping and Wave reflection.

Outstanding structural integrity

The structural integrity of the Xbloc was evaluated by using:

  • Prototype drop tests [The Netherlands, Georgia, Ireland and U.A.E.];
  • Finite element calculations.

Dean Kamen, who invented the Segway and several groundbreaking medical devices, has put a decade of work into a water purifier that he calls the “Slingshot.” This idea worth tens of millions of lives. The name is a reference to the story of David and Goliath — to Kamen, waterborne disease is a Goliath of a problem, and technology is the slingshot.

 

Dean Kamen’s Slingshot water purifier and Stirling generator tech – low cost water and power for the developing world

The water purifier Slingshot uses a fraction of the power of alternatives and a Stirling engine based power generator works on a standard electric grid, solar cells, batteries, or even methane from animal dung.

  • The $ 1,500 water purifier will produce 1000 liters of water a day!
  • The $ 3,700 generator produces around 1 kW, which is enough to deliver light to a small village.

The Slingshot system of vapor compression distillation basically boils and then condenses any dirty water source.

In a partnership with Coca-Cola, Kamen’s firm DEKA Research and Development brought Slingshot to communities in need of clean water in parts of Latin America and Africa. Interested in cooperation? Look below and contact Dean.

Pharmafilter: biological cleaned water saves millions

Pharmafilter is an integral concept for the healthcare, treatment of waste and purification of wastewater for hospitals.

This filter system saves hospitals thousands of dollars a year because:

  • the water is clean without species of medicals in it
  • the proces is much more efficient
  • easier for the patient and its nursing staff
  • there is more efficiency and hygiene in handling the hospital waste
  • less contact moments with contaminated waste
  • locally the solid waste and wastewater are processed, purified and stripped of all harmful substances for people, animals and the environment

Optimal processing, fermentation and disposal of waste and treatment of wastewater.

The installation of Pharmafilter processes and purifies the waste and sewage in the grounds of the hospital. The sewer connections have put a connection to the sewer.

Pharmafilter tontoThe Tonto grinds the waste of the hospital department. It closes with the foot pedal and then the waste is ground within the sealed container. After use container cleans and disinfect itself. After this treatment, the valve automatically opens and is ready for use again. The Tonto consumes 0.11 kWh and about 9 liters of water per flush.

Delta Works keep Holland dry

Delta Works keep Holland dry

60% of the Dutch are living below sea level

The Delta Works is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine-Meuse-Scheldt delta from the sea. Needed because 60% of the Dutch live below sea level

The works consist of damssluiceslocksdykeslevees, and storm surge barriers. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised.

Along with the Zuiderzee Works, Delta Works have been declared one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.

Delta plan to prevent because of the rising of the sea level – climate change

In September 2008, the Delta commission presided by Dutch politician Cees Veerman advised in a report that the Netherlands would need a massive new building program to strengthen the country’s water defenses against the anticipated effects of global warming for the next 190 years. The plans included drawing up worst-case scenarios for evacuations and included more than €100 billion, or $144 billion, in new spending through the year 2100 for measures, such as broadening coastal dunes and strengthening sea and river dikes.

Floods

Water has always played a central part in Dutch history. On one hand it brought wealth to the Netherlands through trade and fishery; on the other hand it brought a number of losses through the many floods. To date water has remained important for the Netherlands. From a geographical point of view, the Netherlands are placed in a very favorable position; at the sea and in the delta (a triangular section of land at the mouth of a river) of four large rivers.

Drained area’s

The Dutch surface area has almost doubled through centuries of “poldering” (area drained and prepared for agriculture) lakes and parts of the sea. As a result of this poldering almost 40 percent of the land lies below sea level. Areas include large parts of the highly populated and the economically important west, with cities such as Amsterdam and Rotterdam. To keep these areas dry, superfluous water is continuously pumped out of the polders. Furthermore, the Netherlands is protected from floods through a combination of levees, dunes, dams and barriers.  After the last big flood of 1953, people decided to build the Delta Works; one of the largest built flood protection and water management projects in the world.

SandMotor: Flood protection with nature

SandMotor protects Dutch Coast

The SandMotor project can be regarded as a ‘field laboratory’ of physical and institutional learning and an innovation for mainstream flood protection.

The SandMotor protects the Dutch coast and creates an additional 128 ha of space for nature and recreation.

Every year, the sea takes sand from the Dutch coast. Every five years, Rijkswaterstaat replenishes the shortfall by depositing sand on the beaches and in the offshore area. If we didn’t, the west of the Netherlands, which is below sea level, would be exposed to the sea.

By building the Sand Motor, a peninsula on the Dutch coast, we try to find out whether nature can spread sand along the coast for us. It goes without saying that the Dutch government is not experimenting with the safety of its people: the coastal defenses are at maximum strength now the Sand Motor has done its job.

Besides coast protection, the project creates an additional 128 ha of space for nature and recreation.

Flood protection

In flood protection, the dominant paradigm of ‘building hard structures’ is being challenged by approaches that integrate ecosystem dynamics and are ‘nature-based’. Knowledge development and policy ambitions on greening flood protection (GFP) are rapidly growing, but a deficit remains in actual full-scale implementation.

The SandMotor is a large-scale (21.5 Mm3) sand nourishment project. This project confirms that an integrated knowledge arrangement enables GFP as it allows for multi-functionality. Effectiveness of the integrated arrangement in this project is explained by its ‘flexible’ nature providing ample design space. This was possible because core values in flood protection and nature were not part of the integrated arrangement.

Construction

Between March 2011 and November 2011, Rijkswaterstaat and the provincial authority of Zuid-Holland created the hook-shaped peninsula. It extends 1 km into the sea and is 2 km wide where it joins the shore.

Trailing suction hopper dredgers picked up the sand ten kilometers off the coast and took it to the right place. Two offshore replenishment locations alongside the peninsula are also part of the Sand Motor. The SandMotor project can be regarded as a ‘field laboratory’ of physical and institutional learning and an innovation for mainstream flood protection.

Aquifer Model Management

Aquifer groundwater management tool

A successful groundwater management requires precise information on groundwater quantity and quality, its renewability and the hydrogeological structure of the underground.

The importance of an Aquifer.

The available drinking water resources in aquifers, are globally declining because of overexploitation and pollution.

Climate Change

Irresponsible use of groundwater from aquifers as the largest freshwater reservoirs in dry areas have already without negative influences of climate change very low groundwater recharge at present but often storage non-renewable partly enormous fossil groundwater resources accumulated in former periods of earth history.

For a sustainable use of these aquifer resources, an adapted and forward-looking groundwater management is of vital importance.

Data management

A successful groundwater management requires precise information on groundwater quantity and quality, its renewability and the hydrogeological structure of the underground.

Based on this data, utilization concepts are developed that also consider ecological and socio-economic aspects. The feasibility of these concepts is tested in model experiments that allow the analysis of the present conditions of a groundwater system as well as its possible temporal development.

Aquifer monitoring and modeling

Modeling results are the design parameters utilized in the preparation of water management plans which are used by national and multinational decision-makers and organizations like federal ministries and authorities, geological surveys and water management authorities.

a simple back of the envelope calculation shows that the NWSAS (North-Western Sahara Aquifer System) constitutes a resource for exploitative use for many centuries to come. Under the assumption that 10% of the estimated 10,000 km3 water stored in the NWSAS can be extracted in a technically and economically feasible way, reserves will last for more than half a millennium assuming a constant maximum future demand of 500 m3 /s.

On quantitative grounds therefore the reliance of irrigated agriculture on NWSAS groundwater is not threatened. The scale of the NWSAS and its properties suggest that undesirable consequences from mining will never adversely affect its entire productive potential.
