Laboratory and pilot plant studies investigated methods of achieving the Urban Wastewater Treatment Directive (UWWTD) primary treatment standards (50% suspended solids and 20% BOD removal). Crude sewage from sites in Wessex Water failed to meet these standards by settlement alone. Settlement was ...
Wastewater is treated though primary treatment of the water by way of a micro-sieve to produce a primary effluent and primary sludge. There is secondary treatment of the primary effluent by way of a membrane bioreactor (MBR) or an integrated fixed film activated sludge (IFAS) reactor to ...
Alternatively grits may be removed from a wastewater stream in a hydro cyclone. A grit chamber is basically an open channel at the discharge (outlet) end of which a weir or such other obstruction is placed so as to maintain a constant liquid velocity in the channel irrespective of the liquid...
The fluidized bed UASB performance was studied in this experiment as a primary unit the anaerobic unit the advantage of better generated sludge characteristics and smaller tank volume. The reactor performance was investigated for the treatment of domestic wastewater with unexpected industrial water flows ...
