Also could be used as flocculation sanitizer in wastewater treatment. Comparison with PHMG: the bacteriostatic effect of PHMB to Straw coli, Saccharomyces cerevisiae and aspergillus niger is higher than that of PHMG. Because of the polymer structure of PHMB, bacteria cannot be resistant to it. And this has also been proved with experiment by international authoritative test organization.
