This is a reverse osmosis membrane treatment chemicals . It is highly concentrated polymer chemicals. Antiscalant RXSOL-33-3302-230 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 RXSOL-33-3302-230 can be injected neat or diluted and a site‐specific dosage can be determined using software program.
Antiscalant RXSOL-33-3302-230 offers a variety of critical performance and application benefits:
- Inhibits RO membrane scaling caused by the following:
- Compatible with the polyamide and cellulose acetate RO membranes of the leading manufacturers.
The typical dosage range is between 2 to 5 ppm or Typical dosage range is between 2 and 6 mg/L.. A site‐specific dose can be determined using computer program. Like any injected chemical, over or underdosing may cause unnecessary membrane system fouling. Please contact the Avista customer service department for customized dosing instructions.
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.

230 performance is achieved when the chemical is injected downstream of multimedia filters and upstream of cartridge filters. For maximum effectiveness, Antiscalant RXSOL-33-3302-230 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
Standard regional pack sizes are listed below and custom packaging can be provided worldwide. This product should be protected from freezing.

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.
Key Features and Benefits
- Inhibit scale formation and effectively controls corrosion
- Protects the membrane efficiently
- Enhance the plant operation and equipments life span
- Easy in usage and handling
It reduces the risk of scaling and eliminates the use of hazardous acids,resulting in efficient plant operation with highest possible conversion rate.
It is a very effective antiscalant . It is also compatible with RO CHEMICALS series of coagulant and flocculants (polyelectrolytes). Our RO Antiscalant (HIGH PH) is effective in minimizing scaling in presence of foulants like Calcium Carbonate, Sulfate salts of Calcium, Barium, Strontium and Magnesium, Calcium Fluoride, Iron and Silica.
Key Features and Benefits
- Effective scale inhibition
- Alkalinity builder
- High recovery rate
- Low Chemical dosage
- Cost Effective
- Effective Iron fouling control by sequestration
- Reduced frequency of membrane cleaning
- Compatible with all types of membranes
- Completely organic and biodegradable
Application and Dosage
Our RO Antiscalant (HIGH PH) is dosed directly to the RO feed water tank or feed water line (after pretreatment) at the minimum recommended dosage of 1ppm and maximum dosage at 15ppm, subject to inlet water quality and parameters is respect of Calcium Hardness, Iron, TDS, Alkalinity, pH and silica content.
In case of high iron content of about 0.5 to 1.0ppm, the dosing has to be increased by 10-15ppm for stabilizing Calcium.
At about 10-15ppm dosage our RO Antiscalant (HIGH PH) is capable of fully inhibiting iron and calcium, and silica up to 166ppm. For higher silica content RXSOL ANTISCALANT should be used.
