Completely biological and sludge-free

Our systems imitates biological processes of natural aquatic ecosystems, where microorganisms interact with plants in a plant-microbial nutritional fabric. The system leave no residual products and no excess sludge. It consists of two robust tanks that are placed underground outdoors, supplemented with energy-efficient pumps for oxygenation and circulation of the water. In one of the tanks, plants are planted with a bushy root system, which creates a cleansing environment. The purified water can be recycled and used for example as toilet water, for irrigation, and after filtration, as drinking water.

Modular systems

Our systems are modular and can be expanded for large-scale use, such as wastewater management from several properties to a larger joint treatment plant. Our solutions for industrial activities with high water consumption works for businesses as process industry, car washes, wastewater treatment from landfills, plus efficient and maintenance-free restoration of lakes and dams. Contact us if you want to know more about our biological water treatment systems for properties and for industrial activities. You can reach us via our contact page here on the web or by phone.
