Conventional Sanitation is not Sustainable

• Infiltration of nutrients

• Contamination b Chemicals

(Emerging Contaminants)• High Water Consumption

• High Energy Consumption

Closed-Loop Sanitation

• Recycle of nutrients

• Re-use of water

• Energy recovery from waste water

• Alternative collection system

• Advanced treatment technologies

• Integrated Waste Water anagemen

→ Technologies will be integratedWater + Energy + Nutrients

→ Solutions will be complex

Aspects of Waste Water Solutions

Water – Energy – Nutrients Integrated Systems

• Treatment– Mechanical: filter, membranes

– emca:–

Biological: aerobic, anerobic• Energy Conversion

– Incineration– Gasification: syngas production– Anaerobic digestion–

Bio-electrochemical systems– Thermal recovery

• Recycling of Nutrients– Phosphorus– Nitrogen

•

– central, decentralised– Integration: Power, Waste, Reuse/Recycle




Energy Recovery: Waste Water and Food Blending

Energy available in waste water is 2 to 4 times the amount required for treatment

Conclusion

• Sustainable solutions are complex and requirement specific• ,

energy as much as possible• Different technologies from different vendors fit to different

situations – there is no “one solution fits all”•

Consistency, interoperability, interchangeability must beensure
