RPI-4500A

Summary

Product identification

ROPUR RPI-4500A is a scale inhibitor specially designed for RO systems.

General

RPI-4500A is a stabilized solution of organic phosphonates and polyacrylates. It is effective against calcium, strontium, and barium sulphate scales, as well as calcium carbonate scales. It also prevents silicate scale formation. RPI-4500A is suitable for use with polyamide, cellulose acetate, and polyether membranes with anionically charged surfaces.

Application and Dosage

• Use: Highly efficient scale inhibitor for cellulose acetate and polyamide membranes. No interaction with membrane material.
• Dosage Control: Proportional to feed water flow using standard metering pumps.
• Fitting Materials: PE, PP, or coated steel.
• Dilution: Can be diluted with water in any ratio. Injecting undiluted or as a solution up to 10% is recommended. Diluted solutions must be consumed within 48 hours.
• Dosage Level: 1 – 8 ppm as delivered, depending on operating conditions and water composition.
• Handling: Easy to handle, no aggressive components. pH is slightly acidic.
• Container Cleaning: Clean containers with a 10% sodium bisulphate solution periodically to avoid biological fouling.

Physical Properties

• Appearance: Clear, slightly yellow liquid
• Density: 1.14 – 1.17 g/cm³
• pH-value: 4.0 – 4.3
• Freezing point: -10 °C
