Non-Oxidizing Biocide - Liquid
RoCide® IS2 is an extremely effective, non-oxidizing biocide based on a 1.5% isothiazolin mixture. It is a broad-spectrum formulation for use against microbiological contaminants commonly found in RO applications including bacteria, fungi, and algae.
RoCide® IS2 is designed to be fed continuously to the reverse osmosis system feedwater and may be used alone or in conjunction with another Avista biocide; RoCide® DB-20. Alternatively, RoCide® IS2 can be applied intermittently and it is also highly effective as a preservative.
This chemical is formulated specifically for use in RO system feedwaters and is to be used in non-potable applications only.
RoCide® IS2 offers a variety of performance benefits:
- Broad-spectrum biocide that kills bacteria, fungi, and algae.
- Certified by the U.S. Environmental Protection Agency (EPA) for use in reverse osmosis systems.
- Compatible with polyamide and cellulose acetate membranes.
- Degrades rapidly and naturally to comply with strict environmental discharge regulations.
- Can be used in conjunction with other applicable Avista Technologies chemicals.
For continuous dosing, RoCide® IS2 should be injected into the RO feedstream at an initial dose of 15 ppm. This dosage should be continued for one to two weeks. After this period, bacterial counts in the feed and concentrate streams may be used to determine when the dosage can be reduced, typically to 5 ppm or less.
Microbiological control is generally achieved when the concentrate bacteria counts fall below those found in the feedstream (taking the concentration factor into account).
Alternatively, RoCide IS2 can be applied intermittently at 50-100ppm for 4-6 hours per week. It is also highly effective for train preservation with the above dose controlling biological growth in offline trains for extended periods.
