Study and Application of Stability of Natural Organic Polymer Coagulants

Abstract

The natural organic polymer coagulants have attracted much attention due to their safety, non-toxicity, good biodegradability and abundant sources of raw materials. However, the instability of coagulants has restricted their further development and application. In this paper, the main types of coagulants, the research of unstable performances and improvement measures are reviewed. Meanwhile, the applications in water treatment are introduced. Finally, the development prospects of coagulants are prospected in order to provide new ideas for the further study of natural organic polymer coagulants.
