Chitosan and its derivatives in wastewater treatment application

Abstract

Chitosan, a versatile and environmentally friendly biopolymer derived from chitin, has emerged as a promising material for wastewater treatment applications. Its unique properties, such as biodegradability, biocompatibility, and adsorption capacity, make it an attractive option for addressing the growing challenges of water pollution. This paper provides a comprehensive review of the use of chitosan and its derivatives in various aspects of wastewater treatment. It explores the synthesis and modification of chitosan to enhance its effectiveness, discusses its mechanisms of action, and highlights its applications in coagulation, flocculation, adsorption, and membrane processes. The paper also delves into the challenges and future prospects of chitosan-based wastewater treatment, emphasizing the potential role of this natural polymer in sustainable water management. The wastewater from common effluent treatment plant (CETP) was used for treatment and significant results are obtained.
