Polymerization rates of silica at various concentrations and pHs have been studied via nephelometry. The ability and potency of ultrasonic radiation on the coagulation process in aqueous samples with and without silica colloidal particles have been extensively investigated. Factors affecting the rate and filtration volume such as silica concentration, time of radiation, temperature, and fre...

introduction: colloidal materials and suspended solids cause turbidity in water. to remove turbidity, clarification method is used that includes processes of coagulation, flocculation, and sedimentation. due to the long duration of coagulation process, coagulant aids are applied. despite the favorable efficiency of synthetic polyelectrolytes as a coagulant aid, due to their harmful effects on h...

Following biological treatment, wastewater continues to have endotoxic active materials. However, because there is a trend of potable reuse and because endotoxic active materials potentially have harmful effects on human health, their removal from water is crucial. Lipopolysaccharide endotoxin has hydrophobic groups, and their removal using a coagulation-flocculation alternative is believed to ...

The processes of coagulation and flocculation using high molecular weight long-chain polymers were applied to treat mine water having fine flocs of which about 93% of the total mass was less than 3.02 microm, representing the size distribution of fine particles. Six different combinations of acryl-type anionic flocculants and polyamine-type cationic coagulants were selected to conduct kinetic t...

Coagulation-flocculation is a critical treatment to reduce operational problems at Drinking Water Treatment Plants (DWTPs), created by episodes of cyanobacterial blooms in surface waters. There need for the search good coaguflocculants that avoid release intracellular toxins safer sustainable production. Clay-polymer interactions were examined development efficient composites their use as Micro...
