This paper summarized the effect of influent category,dissolved oxygen(DO),pH,solids-retention time(SRT) and loading rate(Ns) on the composing of EPS,and analysed the effect of EPS on surface characteristics(hydrophobicity and Zeta potential),flocculating and settling,dewatering,adsorption and regeneration of activated sludge.

Study on the flocculation performance of hydroxymethylation melamine modified polyacrylamide flocculant;

This paper studied the treatment of iron-wastewater by using flocculation and sedimentation under static condition.

The fundamental cause of generating influence on the settling velocity by ions is flocculation of fine sediment.

The turbidity of wastewater can be reduced to below 10mg/L by the process of flocculating settling and filtration.

In normal atmospheric temperature and pressure,after original wastewater of COD_(cr)180000mg/l was treatmented used alkaline hydrolysis,SBR of efficient and low power consumption and flocculating settling methods,it was came up to a set emission standard of organophosphorus pesticide industrial wastewater for every technical .

Aluminum flocculants have an important role in the flocculation and settling of fine sediment, and are often used to clear muddy water and treat agricultural waste water.
