How to precipitate colloidal particles?
View：0 Add Time：2025-07-05
In order for colloidal particles to precipitate, measures need to be taken to promote their mutual contact and coalescence into large particles. This can be achieved through techniques such as coagulation, flocculation, and coagulation. Agglomeration method is to add positively charged coagulants to wastewater to eliminate electrostatic repulsion between colloidal particles and promote particle aggregation. Common coagulants include aluminum sulfate, ferrous sulfate, alum, and ferric chloride. Through these methods, colloidal particles can aggregate and precipitate with each other.
