Solid and liquid/solid free fraction of the wastewater can be separated from existing wastewater stream. The solid fraction is directed into biogas plant and liquid/solid free fraction can be treated with Natured Based Solution (NBS) indoor and/or outdoor with a minimum energy cost (<1.5 kWh/m3) and allowing >95% water reuse. The effluent water can further be disinfected (by using O3/UV) and used for vertical farming and gardening as well as toilet flushing. The solid fraction can be used for biogas production in a anaerobic digestion unit (Solution 8).
The feasibility of this water treatment solution will be demonstrated at laboratory and pilot scale. The potential reuse of treated water for toilets or irrigation will be quantified and demonstrated by ALCN.
