Polymers for Coagulation and Flocculation in Water Treatment

The classification of the synthetic organic polymers used in water and wastewater treatment operations is based on the ionic charge present, e.g. cationic, anionic and non-ionic polyelectrolytes. Cationic polyelectrolytes formed the largest number of polymeric coagulants that have been used in CF operations.

application progress of enhanced coagulation in water treatment

Application progress of enhanced coagulation in water treatment

The BSF process improves the sedimentation speed and overflow rate, reduces the footprint of the system, and greatly reduces the cost of coagulation treatment. Many researchers have conducted in-depth research. For example, Desjardins 17 conducted comparative experiments in three different water treatment plants, and the results showed that the amount of coagulant was the key parameter that

Analysis and optimization of coagulation and flocculation process | Applied Water Science - Springer

The coagulation flocculation is considered the most important process in water surface treatment. Coagulation allows by the injection and the scattering of chemical (coagulants) during relatively intense mixing to destabilize naturally occurring particles and macromolecules and/or to precipitate additional particles (Mackenzie and Cornwell 1991 ).

a review on application of flocculants in wastewater treatment

A review on application of flocculants in wastewater treatment

? Flocculants are divided into three groups: chemical, natural and grafted flocculants. ? Methods of wastewater treatment: coagulation¨Cflocculation and direct flocculation. ? Flocculating efficiency of bio-flocculants is comparable to chemical flocculants. ? Flocculating mechanisms: charge neutralisation, bridging and electrostatic patching.

Challenges and Opportunities of Biocoagulant/Bioflocculant Application for Drinking Water and Wastewater Treatment and Its Potential for Sludge

For wastewater treatment, the cost of using chemical coagulants/flocculants per m 3 also varies, i.e., USD 0.10 when using alum and USD 0.15 when using ferric chloride to treat meat processing effluent [], USD 19 to treat palm oil mill effluent by using alum [].

Full article: Characterization of alum floc in water treatment by image analysis and modeling - Taylor & Francis Online

Public Interest Statement. In this article, we introduce a low-cost camera application, which is suitable for characterization of alum floc in water treatment processes. The application is capable to produce different floc describing parameters to produce parameter such as floc size or floc number by image analysis.

Sterilization by flocculants in drinking water treatment

Coagulation-flocculation and sterilization in drinking water treatment were simultaneously achieved via dosing PAC and PDMDAAC in a cost-effective way. Two flocculants played the different roles in the treatment. PAC played role of coagulation, charge neutralization, but PDMDAAC with quaternary ammonium groups was responsible for flocculation
