Antiscalant Polymer
This is a reverse osmosis membrane treatment chemicals . It is highly concentrated polymer chemicals.
RXSOL Antiscalant water additives, used as pretreatment for Reverse Osmosis systems, are highly effective in preventing membrane scaling. Applied Membranes carries a large inventory of RXSOL Antiscalant at competitive prices with technical support. Our design engineers can help you determine the proper dosing for our application. Most products in stock for immediate shipment.
Without some means of upstream scale inhibition, RO membranes and their flow passages will foul due to scale, the precipitation of sparingly soluble salts. Common examples of scale are calcium carbonate (CaCO3), calcium sulfate (CASO4), barium sulfate (BaSO4), and strontium sulfate (SrSO4). Less common but equally problematic are silica (SiO2) and calcium fluoride (CaF) scales.
Dissolved iron salts are stabilized through the sequestration mechanism, in addition, suspended sediments containing iron in the form of Fe (OH) 3, FePO4, FeCO3 will stabilize through the dispersion mechanism. A reagent having such a double action remains effective over a wide pH range (6
RXSOL Antiscalant is an aqueous solution of an organic chemicals. RXSOL Antiscalant is miscible with water in all proportions. It may be applied as the neat product, or as a solution in permeate. RXSOL Antiscalant should be dosed continuously and proportionately to the feed water flow, to maintain the recommended dose level.
The dose level required is dependent on the quality of the saturation indices of the various scales forming species present in the concentrated brine. Proprietary computer software is used to calculate scaling indices and calculate optimum system recovery. Dose level projections and recommendations are available on
request.
Dosage
To prevent precipitation of metal oxides, it is necessary to maintain a constant concentration of RXSOL in the processed system from 2 to 50 mg / dm3. The optimum dose of reagent depends on the amount of sediment in the system and the controlled parameters. When RXSOL-33-3302-020 is used as the sole treatment facility, the reagent dose should be higher than when used together with other reagents.

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.
Key Features and Benefits
- Inhibit scale formation and effectively controls corrosion
- Protects the membrane efficiently
- Enhance the plant operation and equipments life span
- Economical
- 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.

PHYSICAL PROPERTIES:-
Because RXSOL-33-3302-020 is a highly concentrated product,
It is acceptable to use small doses of reagent.
Suspended substances such as dirt, bottom sediments, clay, metal oxides are dispersed, and their possible precipitation decelerates. The strong dispersing power of RXSOL-33-3302-020 allows the reagent to maintain its efficiency in waters with high total salt content, as well as in areas with a low liquid flow rate. Salts of calcium and magnesium, such as CaCO3, CaSO4, CaSO4 · H2O, MgSiO4, are dispersed, and the formation of their sediments is suppressed.

Precautionary measures : Use protective gloves and goggles. If the reagent enters the skin, eyes, rinse with plenty of water, consult a doctor. If a reagent leakage is collected with sand or other absorbent material, rinse the contaminated surface with water. Before use, read the additional information in the Safety Instructions.
