DWS in a nutshell

DWS (patent PCT/EP2020/085377) non-selectively absorbs, concentrates and retains both suspended and dissolved organic and inorganic contaminants from wastewater generating clean effluent. It is scalable, meets the criteria of customer affordability through retrofitting within existing infrastructure and provides an end-to end solution from water decontamination to toxic free biowaste.

DWS advantages 

  1.  Non-selective removal of a wide range of contaminants

  2. Removal of excess nutrients preventing water eutrophication

  3. CAPEX and OPEX several orders of magnitude lower than conventional technologies

  4. Contaminants are either metabolised into environmentally benign by-products or captured in the waterflea body

  5. Treated biomass is reused, enabling a circular approach to wastewater treatment.

DWS net-zero carbon promise

The end product of the oxidation process is clean water which can be reused plus residual biomass purged of all toxic compounds that is recycled in the anaerobic digestion process, upstream of wastewater works, achieving circularity and meeting the net zero-carbon target of the international agenda for decarbonisation.

How it works?

Waterfleas are introduced in extant tertiary treatment tanks in interconnected buoyant cages in a modular system. The system consists of multiple cages floating on the top meter of the tanks where light penetration is ideal for waterflea survival and where a vertical flow brings the wastewater in contact with the biological agent. The modular cages are interconnected by a manifold syphon system, designed and optimized using computational fluid dynamics, that prevents waterfleas from escaping from the containment volume, while collecting biomass enriched with contaminants. This systems enables cage maintenance and an uninterrupted removal of pollutants. It also prevents dispersal of the biological agent, potential competition with other ‘natural residents’ of the wastewater tanks and meets the criteria of customer affordability through retrofitting within existing infrastructure.
