How Effective Is Coagulation?

How Effective Is Coagulation?

Feb 08, 2022 · Coagulation is the chemical water treatment process used to remove solids from water, by manipulating electrostatic charges of particles suspended in water. This process introduces small, highly charged molecules into water to destabilize the charges on particles, colloids, or oily materials in suspension.

Based on the results of the dairy farm water, MNSs showed the best performance at a 75% ratio of MNPs to coagulants. Therefore, only three ratios (i.e., 0, 75, and 100%) were used for testing. MNSs were formed in situ at a ratio of 75% MNPs to coagulants. The coagulant concentration was maintained at 20 ppm.
