The Role of Environmental Variables in Waste Stabilization Ponds' Morphodynamics

Paolo Perona

In management of helminth infections and transmission, the correct prediction of sludge accumulation patterns in waste stabilization ponds (WSP) is important as sedimented eggs are associated with sludge depth. However, sedimentation in WSP is complicated ...

Ozonation of municipal wastewater effluent containing metal sulfides and metal complexes: Kinetics and mechanisms

Urs von Gunten

Ozonation can be applied to mitigate the discharge of organic micropollutants from municipal wastewater treatment plants (WWTPs) to the aquatic environment. The toxicity of metals also present in WWTP effluents strongly depends on their speciation. Therefo ...
