RoCide IS2

RoCide IS2 liquid is a broad spectrum, non-oxidizing biocide intended for continuous injection and specifically formulated for reverse osmosis (RO) feedwaters. It is slower acting than some other biocides but is more stable for continuous injection. It is based on a 1.5% isothiazolinone mixture. This slow-acting biocide is powerful against microbiological contaminants commonly found in RO applications including bacteria, fungi, and algae. RoCide IS2 is designed to be fed continuously to RO system feedwaters and may be used alone or in conjunction with RoCide DB20. Alternatively, RoCide IS2 can be applied intermittently and is also highly effective as a preservative. It can be used in waters containing high sulfites up to 25 ppm of sulfite or bisulfite.
