Roles of baffles in waste stabilization ponds
Water Science and Technology, 1997 Performance of baffles in waste stabilization ponds (WSP) comprising laboratory-scale ponds with different number of baffles was evaluated. This study was aimed at promoting waste stabilization ponds practice for wastewater treatment in tropical countries by reducing the land area requirement through the use of baffles which increased the biofilm and ...

Waste stabilization ponds: Past, present and future [PDF]
Desalination and Water Treatment, 2009 The ‘past’ of waste stabilization ponds (WSP) is due to early experience and design codes in the USA and also to two pioneering researchers, Oswald and Marais. The ‘present’ of WSP dates from the mid-to-late 1970s and is characterized by large numbers of full-scale systems in France, Germany and the USA.

Cotreatment of sewage and septage in waste stabilization ponds
Water Science and Technology, 2002 A one year study was carried out in a waste stabilization ponds system where septage and sewage are cotreated. The system consists of two septage ponds which operate alternately followed by two ponds in series which receive the combined effluent. The septage ponds also act as evaporation ponds for the accumulated sludge.
