Decentralised Treatment Facility (DTF) offers a sustainable solution for managing wastewater in low-income areas. The concept involves various modules such as Receiving Bay/Balancing Tank, Settler, Anaerobic Baffled Reactor, Vertical Flow Constructed Wetland, Sludge Drying Reed Beds, Composting Area, and Operator Store. The treatment process is chemical-free and operates without electricity, relying on mechanical and biological treatment run by gravity. Each module plays a crucial role in treating wastewater efficiently, from initial screening to compost production.
