What is the difference between coagulation and flocculation?
Coagulation and flocculation are two essential processes used in water treatment to remove impurities and particles from water. While they are related and often used in conjunction, they serve slightly different purposes: Coagulation: Coagulation is the initial step in water treatment, where chemical coagulants are added to the water. The most common coagulants are Aluminum Sulfate (alum) and ferric chloride. These chemicals are added to destabilize the charged particles (colloids) present in the water. The coagulants work by neutralizing the electrical charges on these particles. Particles in water typically have a negative charge, and the coagulants introduce positively charged ions. This neutralization reduces the electrostatic repulsion between particles, allowing them
