Applications of RXSOL 3935

1. Cooling Water Treatment

Microbiological growth in cooling-water systems can lead to slime, biofilm, biological fouling, reduced heat-transfer efficiency, and corrosion under deposits.

RXSOL 3935 can be incorporated into a properly designed cooling-water treatment program to help control microorganisms and maintain system cleanliness.

2. Once-Through Cooling Systems

Once-through cooling systems can also experience microbiological fouling. Sodium hypochlorite-based oxidizing treatment can help control biological growth when applied according to system requirements and applicable regulations.

3. Reverse Osmosis Pretreatment

Microbial growth can cause serious biofouling of RO membranes. RXSOL 3935 can be considered for upstream microbiological control where compatible with the overall RO pretreatment program.

Because many polyamide RO membranes are sensitive to free chlorine, adequate dechlorination is generally required before treated water reaches the membrane. The treatment system should therefore be designed and monitored accordingly.

4. Wastewater Treatment

RXSOL 3935 can be used in selected wastewater-treatment and disinfection applications where oxidizing microbiological control is required.

Treatment dosage depends on factors such as organic load, pH, temperature, contact time, water quality, and the required disinfection performance.

5. Water Disinfection

Sodium hypochlorite-based products are widely used for disinfection of suitable water streams. Proper dosing and contact-time control are important to achieve the required microbiological reduction while managing residual chlorine.
