Coagulants Used in Water Treatment

Coagulants are chemicals used in water treatment to remove impurities and solids from water. Coagulants work by causing small particles to clump together and settle at the bottom of the water supply, which can then be filtered out.

Function Better When Raw Water is Alkaline

The effectiveness of coagulants in water treatment is influenced by the pH of the water. Coagulants function better when raw water is alkaline. This is because the coagulant reacts with the alkalinity in the water to form a gelatinous mass, which is more effective in removing impurities from the water.

When the raw water is acidic, the coagulant has a reduced ability to function effectively. This is because the acidic water reduces the effectiveness of the coagulant, making it less effective in removing impurities from the water.

Neutral or slightly alkaline water is the ideal pH for coagulants to function effectively in water treatment. This pH range allows the coagulant to react with the alkalinity in the water to form a gelatinous mass, which is effective in removing impurities from the water.

Cracking of Filters

If the raw water is too acidic or too alkaline, it can cause problems with the filters in the water treatment process. Acidic water can cause the filters to crack, while alkaline water can cause the filters to clog.

Therefore, it is important to maintain the proper pH range in raw water to ensure the effectiveness of coagulants in water treatment and to prevent damage to the filters.
