MICROTREAT 2100 is a non-oxidizing, liquid, antimicrobial formulation with a broad spectrum of biocidal activity, used in large open cooling systems and similar sized bodies of water. It is designed to prevent the growth of biofilms on heat exchangers and evaporative surfaces and to control the number of planktonic microorganisms in the bulk fluid. It is non-foaming and compatible with non-ionic, cationic and anionic chemicals.
