Chitosan flocculant water treatment
WebFlocculants, or flocculating agents (also known as flocking agents), are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles. WebThe process of extracting chitosan from natural raw materials mainly includes three steps: demineralization, deproteinization, and deacetylation. At present, the most common commercial extraction method of chitosan is the chemical method using …
