Bluewater clean drinking water solution

Bluewater Pro water purifier can generate up to 1,826 US gallons (6,912 L) of purified water a day

Bluewater purified water solution allows communities all over the world to turn polluted and waste water into clean drinking water.

The company’s global overview on the development of water treatment systems is related to the environment, plant breeding, and biotechnology improvement.

Bluewater SuperiorOsmosis™

Their approach focusses on phytodepuration (phyton = plant and depurare = clean, purify). That process eliminates contaminant agents from waste waters by means of complex biological and physicochemical processes involving plants in the aquatic ecosystem.

Phytodepuration occurs naturally in ecosystems which receive contaminated waters, and it has been the classical system for water quality recovery, together with water self-purification. The process occurs in natural wetlands as well as in constructed ones.

Refill your plastic bottle

Bluewater phytodepuration is applied as photosynthetic organisms intervene, and those organisms can be plants or macroscopic or microscopic algae.

Removing lead and most other toxic metal, chemical, and organic contaminants from tap drinking water, a high-performance Bluewater Pro water purifier can generate up to 1,826 US gallons (6,912 L) of purified water every day, which substantially reduces the need to purchase single use plastic bottles.

The technology also slashes the water wastage commonly associated with reverse osmosis by up to 79%.

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.

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.

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.

Slingshot: the ultimate seawater purifier

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.

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.
