Why doesn't garbage stick together in water? An explanation of how flocculation works with coagulants.

■What is floc? Floc refers to a mass of particles formed by the precipitation of chemicals added as coagulants in water treatment. This floc exhibits coagulation reactions against suspended solids, organic matter, bacteria, and coloring components in the water, resulting in purification effects. ■Why do they stick together when coagulants are added? Debris in water typically has a negatively charged surface, which causes it to repel each other and makes it difficult to stick together. By adding coagulants, this repulsion is neutralized, allowing the debris to clump together into larger masses, making them heavier and easier to settle. ■What happens to the floc afterward? The large floc that has grown is separated through sedimentation in a settling tank, as well as removed from the water through flotation separation and filtration. Coagulants include inorganic coagulants that neutralize charges and gather fine particles, and polymer coagulants that further bridge and grow these into larger floc, which are used in stages. ■How is coagulation treatment utilized? Coagulation treatment is a fundamental technology widely used in various water treatment settings, such as wastewater treatment and drinking water treatment. It is important to adjust the type and amount of coagulant based on the type and concentration of contaminants. Please feel free to consult with us first.
