Coagulation Water Treatment. Coagulation water treatment is the process of destabilization by charge neutralization. Once neutralized, particle no longer repel each other and can be brought together. Coagulation is necessary for the removal of the colloidal-sized suspended matter.
Types of Coagulants used in Water Treatment Process
Sodium aluminate. Another widely used types of coagulants is sodium aluminate. Sodium aluminate is prepared from aluminium oxide stabilised with caustic soda; it is used with aluminium sulphate to coagulate very cold waters which would not coagulate successfully with aluminium sulphate alone.
Coagulation is a conventional step of water purification and bio-coagulants are new horizon to go green. Cicer arietinum, which is known as chickpea and Moringa oleifera seed can be used for the...
Chemical Coagulants Used In Water Treatment | SNF
Inorganic coagulants are particularly effective on raw water with low turbidity and will often treat this type of water when organic coagulants cannot. Once added to water, the inorganic coagulants form aluminium or iron precipitates. These absorb impurities in the water as they fall, serving to clean the water.
The treated water pH is 7.0-7.2 after getting a “boost” from hypo addition for disinfection, since disinfection with sodium hypochlorite actually raises the pH of the finished water. Ferric coagulants also work well over a wide pH range and often can be used at the higher end of the range, say from 7.5 to 8.0.

Seán Moran, in An Applied Guide to Water and Effluent Treatment Plant Design, 2025. Coagulants. The most commonly used coagulants are metallic ions with a high charge density, though there are also now some organic coagulants, similar to flocculants but with lower molecular weight.
Coagulation is a conventional step of water purification and bio-coagulant is a new horizon to go green. Cicer arietinum, which is known as chickpea, can be used for the treatment of surface water.

Tacelene Chem 4118 is a liquid coagulant based on polyamines used in water clarification. They may be used independently or supplemented with inorganic coagulants or with coagulants aids based on polyacrylamide. Tacelene Chem 4118 is efficient in removal of organics and oil from process water.
ULTRAFLOC 3200 is a aluminium chlorohydrate coagulant blend designed to provide superior coagulation for clarification of raw water and effluent water. ULTRAFLOC 3200 has the advantage of having little or no effect on water pH. ULTRAFLOC 3200 is generally dosed as product with in line dilution at the dosing point.
Coagulation and Flocculation for Raw Water
Coagulation and Flocculation for Raw Water Nalco offers a comprehensive suite of organic and inorganic blended coagulants and organic flocculants. We can work with you to optimize the performance of your treatment program, including chemicals and equipment, which can dramatically minimize your overall costs and maximize return on investment.
coagulation dosing in drinking water Many water quality parameters provide information relevant to coagulation. These include pH, temperature, conductivity, turbidity, suspended solids, UV absorbance, colour, TOC, alkalinity, total-P, surface charge/zeta potential, and ortho-P concentration.

- Can powder polyacrylamide flocculants be fed to sewage?
- Powder polyacrylamide flocculants couldn’t be directly feed to the sewage. It is necessary to dissolve it in water first and then use its water solution to treat the sewage. The water to dissolve the granular polymer should be clean (such as tap water), rather than sewage. The water at the normal temperature is workable, no need to be heated.
