The effects of different pH value and SAF dosage on the sedimentation behavior of SiC in the slurry were studied using 10% (in mass) polyvinyl alcohol (PVA) water solu- tion as a medium.

Diameter of magnetic-responsive particles is tested by SEM and gravitaional sedimentation,Diameter of responsive particles as function of sedimentation constant and magnetorheological behaviors are analysised,At the same time,the magnetization characteristic and tribological characteristic are studied.

Loosely bound EPS(LEPS) and tightly bound EPS(TEPS) were extracted by ultrasonic and cation resin in turn,and the influence of two type EPS and their surface characters to the settleability of activated sludge were investigated.

Coalification ranking affected to settling performance of slurry water;

The settling performance of digested red mud pulp during sweetening process was investigated with Weipa ore from Australia and Al(OH)3 as additions.

In this experiment,the effects on settling performance of granular sludge in the ASBR have been investigated at the ranges of MLSS 9.

This paper analyses EPS's effect on floceulation,settleability,dewaterability and metal absorbing in sludge treatment system.

The experiments of sludge settleability and filtration performance show that the mixture of three agents at the ratio of 1 ∶2 ∶0.

Based on biochemical methane potential (BMP) and toxicity assay on anaerobic biomass at different concentration of polyquaternary amine, an appraisal was conducted on anaerobic biodegradability of polyquaternary amine, and comparison was made on the effect of various polyquaternary amine concentration on specific methanogenic activity (SMA) and settleability (SVI) of anaerobic biomass.

The targets of the study are as follows: synthesizing Fe_3O_4 nano-particles; study on effect of Fe_3O_4 nano-particles on settling ability and dewaterability of sludge and their function mechanism, effect of co-.
