Sterilex® Ultra-Kleen Solution 1 Liquid Biocide

Sterilex® Ultra-Kleen Solution 2 Liquid Biocide

Product Description

EPA Reg. #63761-3

Sterilex Ultra-Kleen  Solution 1 & 2 Liquid Biocide is low-foaming, EPA registered, hybrid non-oxidizing biocide, oxidizing biocide, and biofilm removal agent. Based on our proprietary PerQuat® technology, Sterilex Ultra- Kleen Solution 1 & 2 Liquid Biocide acts as a biocide and biofilm removal agent that rapidly eliminates resistant organisms, biofilm, mold, and algae from industrial water systems, where alternatives such as chlorine, peracetic acid, and chlorine dioxide are not effective. Sterilex Ultra-KleenSolution 1 & 2 Liquid Biocide is effective against sulfate-reducing and slime-forming bacteria and can be used for both rapid remediation as well as ongoing system control applications. When used in cooling tower systems with a pH ≥ 8.5, Solution 1 is used alone. In closed loop systems or if the pH is < 8.5, the two Sterilex Ultra-Kleen Liquid Biocide Solutions are mixed together at the time of use.
