Chitosan flocculant water treatment
WebChitosan is a weak base and is insoluble in water and in organic solvent. However, it is soluble in dilute aqueous acidic solutions (pH<6.5), which can convert glucosamine units into soluble form R–NH+ 3.Chitosan is inexpensive, biodegradable and nontoxic for mammals(Qin et al.,2006). Chitosan molecule has the ability to interact with WebIn particular, the development of chitosan-based materials as useful coagulants and flocculants is an expanding field in the area of water and wastewater treatment. Their coagulation and flocculation properties can be used to remove particulate inorganic or organic suspensions, and also dissolved organic substances. This paper gives an …

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. WebJul 5, 2024 · Through adsorption, bridging, and enmeshment effects, flocculants can dispose of suspended particles, colloids, and dissolved organic matter, and promote agglomeration by making “bridges” between these flocculants, causing them to agglomerate and precipitate out of solution.
