ROCARE A31

Premium Membrane Antiscalant

DESCRIPTION:

ROCARE A31 is a premium broad spectrum antiscalant comprising of synergistic blend of specialized dispersants and scale inhibitors for Reverse Osmosis Membrane.

BENEFITS:

• Broad spectrum antiscalant designed to inhibit inorganic scale formation in membrane separation processes
• Inhibits calcium carbonate scale upto an LSI of 3
• Effectively inhibits formation of Calcium sulfate, Calcium phosphate, Calcium fluoride, Barium sulfate, Strontium sulfate and Silica
• Stabilizes metal ions to prevent metal oxides precipitation and disperses existing metal oxides / hydroxides, silt and clay particles
• Excellent scale control for very high silica water upto 400 ppm

TYPICAL PROPERTIES:

Appearance                : Clear, colourless to yellow liquid

Odor                            : Characteristic Odour

pH (as is) @ 25⁰C       : ≤ 2

Specific Gravity          : 1.15 ± 0.05

Water Solubility           : Completely soluble

APPLICATION:

ROCARE A31 is normally fed continuously prior to the final cartridge filter. It should be injected by chemical dosing pump from a dilution tank or directly from the drum to the feedwater line.

Recommended minimum dosage is 2 to 5 ppm and to maximum of 10 to 12 ppm , subject to inlet water quality in respect of TDS , Calcium and Silica.

Please use acid compatible materials for chemical tanks , pump and piping.

 

ROCARE A21

Broad Spectrum Membrane Antiscalant

DESCRIPTION:

ROCARE A21 is a broad spectrum antiscalant comprising of blend of dispersants and scale inhibitors for Reverse Osmosis Membrane effectively controlling deposition of inorganic scales.

ROCARE B41

Non Oxidizing Membrane Biocide

DESCRIPTION:

ROCARE B41 is a fast acting, non oxidizing biocide. It is environmental friendly as it is non persistent and degrades to naturally occurring products. It provides efficient and cost effective microbiological control.

BENEFITS:

• Effective control of most biofoulants
• Effective control of bacteria, fungi and algae in industrial membrane system

TYPICAL PROPERTIES:

Appearance                : Clear to pale yellow liquid

Odor                            : Characteristic mild pungent odour

pH Undiluted              : 3.0 – 5.0

Specific Gravity          : 1.15 ± 0.05

Water Solubility           : Completely soluble.

APPLICATION:

ROCARE B41 should be added to system inlet water or before any other contamination area ahead of the reverse osmosis unit.  ROCARE B41 should be added with a metering pump on an intermittent basis depending on the severity of contamination and the guidelines specified by the membrane manufacturer.

ROCARE B41 may be fed continuously to the membrane system feed water at the rate of 10 to 100 ppm.  Once treatment is completed, rinsing with feed water should continue until conductivity values in permeate are at or below values before treatment with ROCARE B41.  Badly fouled systems must be cleaned before treatment is begun.

For off-line system disinfection, add 50-170 ppm ROCARE B41 to the off-line cleaning feed tank and re-circulate for 30 minutes to 3 hours.  Frequency of addition should be every 5 days or as needed.

During and for 30 for minutes to 1 hour following chemical addition, permeate and concentrate streams must be diverted to waste.

Please use acid compatible materials for chemical tanks , pump and piping.
