How RXSOL 3935 Works

RXSOL 3935 uses sodium hypochlorite chemistry to provide available chlorine in aqueous systems.

Depending on pH, available chlorine exists primarily as hypochlorous acid and hypochlorite ion. Hypochlorous acid is an effective antimicrobial species that can oxidize and disrupt essential cellular components of microorganisms.

This oxidation mechanism helps control microorganisms in properly managed industrial water-treatment systems.

Benefits of RXSOL 3935

A sodium hypochlorite-based oxidizing biocide such as RXSOL 3935 offers:

• Effective microbiological control

• Oxidizing biocide action

• Liquid-form chemical dosing

• Control of slime-forming microorganisms

• Helps reduce biological fouling

• Suitable for automated dosing systems

• Useful for cooling-water treatment

• Applicable to selected wastewater disinfection systems

• Suitable for selected RO pretreatment applications

• Practical alternative to gaseous chlorine in appropriate applications

RXSOL 3935 for Cooling Towers

Cooling towers and recirculating cooling-water systems can provide favorable conditions for microbiological growth.

If uncontrolled, microorganisms may contribute to biofilm, slime, biological deposits, fouling, and under-deposit corrosion.

RXSOL 3935 can be used as part of an integrated cooling-water treatment program designed around system conditions, microbiological monitoring, water chemistry, and the required oxidant residual.

RXSOL 3935 for RO Pretreatment

RO membrane systems require effective pretreatment to minimize fouling and maintain membrane performance.

Where sodium hypochlorite is used for microbiological control before RO, the residual free chlorine must be controlled because polyamide RO membranes can be damaged by oxidizing agents.

A suitable dechlorination stage should be incorporated where required, and residual chlorine should be monitored before the water enters the RO membranes.

RXSOL Membrane Antiscalant ALKA 191T is a high-performance threshold antiscalant designed to stabilize a wide range of supersaturated salt solutions, helping to prevent scale formation and maintain efficient RO system operation.

It incorporates  to improve the reliability of scale control by ensuring accurate and consistent dosing, thereby enhancing membrane protection and system performance.

 

 

RO antiscant

Scaling is caused in membranes because the level of hardness salts in the water becomes highly concentrated as it passes through the RO unit. In smaller units scale formation can be prevented by base exchange softening the make-up water but for larger systems that is very expensive. We have developed a range of easy to handle, cost effective RO Antiscalant which increase the solubility of the hardness salts so they remain in solution rather than forming scale on the membrane. Our cost effective RO antiscalants will inhibit a wide range of foulants including: calcium carbonate, calcium sulphate, barium sulphate, strontium sulphate, calcium fluoride, silica and iron.

RO Antiscalants are dosed directly to the RO feed water tank or feed water line (after pretreatment) at the recommended dosage of 1-3 mg/L and maximum dosage at 8mg/L, subject to inlet water quality and parameters is respect of Calcium Hardness, Iron, TDS, Alkalinity, pH and silica content. Maximum dilution should be 10% with RO or DI water for temperature less than 30 deg C. For higher temperature the dilution ratio can increase.
