Key facts about Daphne Water Solutions


DWS in a nutshell

DWS 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.

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 tank's top meter, where light penetration is ideal for waterflea survival. A vertical flow brings the wastewater in contact with the biological agent. The modular cages are interconnected by a manifold syphon system, designed and optimised using computational fluid dynamics, preventing waterfleas from escaping from the containment volume while collecting biomass enriched with contaminants. This system 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 an existing infrastructure.

DWS net-zero carbon promise

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