LAVENDER HILL

Design capacity of 2000 m3/d

How It Works

The process begins from the discharge of the septage into discharge troughs. This flows by gravity through the screens and the integrated machines to remove debris and sand. The septage is then dewatered using a coagulant and then screw pressed.
The bio-solids is collected and dried for further composting as organic manure. 
The effluent will then move into the upflow anaerobic sludge blanket tanks for further treatment(UASB). It is in these tanks that methane gas will be generated. The effluent will then move into the Anoxic and Oxic Tanks where nitrification and denitrification takes place respectively.
The last stage is for the effluent to move into the sedimentation tanks. The clear water will finally pass through a UV system for disinfection before final discharge into the sea.
This effluent will meet the EPA standards. Biogas, which comprises of methane, carbon dioxide and hydrogen sulphide would be extracted from the UASB treatment process, after which it would be cleaned for methane to generate electricity mainly to run the plant.
