PROTREAT 363 is a high-performance broad spectrum isothiazolinone-based microbiocide designed for effective control of microbial growth in industrial water systems such as cooling towers, recirculating cooling systems, and holding tanks. It works at very low concentrations to inhibit the growth of bacteria, algae, and fungi, helping to improve system hygiene, reduce foul odours, and maintain optimal water quality. This microbiocide is suitable for use in a variety of industrial applications where microbial contamination can impact system performance or contribute to corrosion and biofilm formation. Regular dosing as part of a water treatment program helps protect equipment and enhance overall efficiency.
