The required dosage of Nalco 77352 depends on water chemistry and site-specific parameters. Your Nalco representative will recommend the optimum dosage necessary to ensure maximum program performance according to your specific system conditions. The product is typically fed via a closed system, defined as a system in which fluid is moved from a closed storage vessel into treated media without exposure to the atmosphere except through normal venting or pressure relief devices.
NALCO 77352 is a specialized industrial chemical product manufactured by Ecolab, designed primarily for microbial control in water treatment systems. It is commonly used as a cooling water biocide to prevent fouling and ensure maximum system efficiency. Because this product is a powerful industrial biocide, obtaining and understanding the —now officially known as the SDS (Safety Data Sheet) —is critical for safe operation, handling, and environmental compliance.
