Application and Development of Green Scale Inhibitor: A Mini-Review

Green scale inhibitor has the characteristics of high-efficiency, multifunctional, non-toxic and biodegradable, so it is widely used in water treatment. Some scale inhibitors such as polyaspartic acid type, polyepoxysuccinic acid type and poly Valley are reviewed in this paper. By investigating green scale inhibitors, it is proposed that the complexes of amino acid scale inhibitors and their copolymers should be the focus of future research. The development direction of new green scale inhibitors is pointed out, which provides reference and basis for the research and development of new water treatment scale inhibitors in the future.
