Antiscalant RO 5300

RO antiscalant

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 feedwater 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. 

A high-performance Antiscalant for RO systems formulated to prevent scale formation and fouling on membrane surfaces. It effectively controls calcium carbonate, calcium sulfate, barium, and strontium scales, even at high recovery rates. The product maintains optimal membrane performance and extends RO membrane life. Suitable for brackish water, seawater, and wastewater reclamation RO systems.

The typical dosage range is between 2 to 5 ppm or Typical dosage range is between 2 and 6 mg/L.

Dilution:

This product is formulated to be injected neat. However, if a dilution is required, use demineralized or RO permeate water. If neither of these is available, softened water may be substituted. The dilution for Vitec 1000 should not result in a solution strength of less than 10%. This guidelin will protect the effectiveness of the internal bacteriostat which inhibits bacterial growth in the drum and feed tank.Maximum dilution is temperature related as shown below.

• Compatible with the polyamide and cellulose acetate RO membranes of the leading manufacturers.

Antiscalant RO is a liquid antiscalant designed to inhibit scale in cellulose acetate and polyamide membrane separation systems. The formulation contains a 35% by weight solution of poly acid that has a tight molecular weight range of 2000.

This product is designed for use in waters that do not have a high potential for colloidal and silt fouling of RO membrane surfaces (i.e. groundwater applications).

Antiscalant RO  can be injected neat or diluted and a site‐specific dosage can be determined.
 

Application:

Antiscalant RO  performance is achieved when the chemical is injected downstream of multimedia filters and upstream of cartridge filters. For maximum effectiveness, Antiscalant RO should be added prior to the static mixer or cartridge filter housing. For potable  the maximum dosage is 10 mg/L. Maximum dilution is 10% with RO permeate or DI water
