Description
The coagulation process has a special role in water treatment so that many studies have been done on the type of optimum coagulant to remove turbidity. Coagulants include substances used to destabilize and attach charged particles to each other. These particles have a negative or positive electric charge, and the coagulants consumed are usually positive, negative, or non-charged, which neutralize and precipitate suspended particles in water.
Turbidity generating substances in water include clay, viruses, bacteria, folic acid and humic acid; minerals such as asbestos, silicate, and radioactive particles. Jar test is used to select the appropriate coagulant as well as its appropriate dosage under different conditions in the treatment process.
Manufactured coagulants of Abrizan Company by special formulations increase the deposition rate of suspended substances, dimensionality and density of deposited substances, and increase filtration and separation efficiency and improve process quality and dramatically reduce the final turbidity. These coagulants have a variety of cationic, anionic, non-ionic, and polymeric types, which are used because of the electrical charge of the suspended particles and the amount of water turbidity. It should be noted that the company has also produced various types of cationic, anionic and non-ionic polyelectrolytes (auxiliary coagulants) for industries that require higher quality clear water in a considerable volume per time.

Calibration of Using Coagulants:
First, choose the appropriate coagulant, depending on the type of solutes and suspended substances in the feed water, and then dilute the required amount of coagulants with the required amount of soft water and inject 3-20 ppm into the feed water. The blow down time of the system or clarifier should be determined by the amount of deposit material. For concrete, soil, and evaporative lagoons, do scrap of floor and body each one to five years.
It is recommended that you consult with the experts of Abrizan technical department throughout the country for use.
