RO Antiscalant efficiently helps in controlling Iron fouling by sequestration

RO Antiscalant serves as a liquid antiscalant that helps in treating the Reverse Osmosis Membrane System manufactured by Chemtex Speciality Limited. It manifests as an effective antiscalant that serves in maintaining the inorganic scales of magnesium, calcium, strontium, iron, fluoride and silica.

Reverse Osmosis (RO) may be regarded as the procedure which involves the deionization and demineralization of water by making it pass through a semi-permeable membrane under osmotic pressure used in reverse osmosis. By utilizing the reverse osmosis membrane for filtration of heavily soiled water, generally tend to result into some serious issues that may lower the capacity of the membrane. Usually, there are three major problems that require constant attention namely –Degradation, Scaling and Fouling of Reverse Osmosis membranes.

These concerns result in abating the system output as they tend to diminish the wastewater purity. Scaling usually occurs on RO membranes when the concentration of the scale-forming substances surpasses the saturation threshold, thereby resulting in addition of solids within the RO feed water. Chemical substances that are considered under scalants are barium sulfate, calcium carbonate, calcium sulfate, strontium sulfate and reactive silica. These substances are too difficult to be removed from RO membranes owing to their low solubility in water. Scaling hinders the performance efficacy of the membranes in decreasing the solids concentration and causes more frequent cleanings.

To avoid encountering these kinds of circumstances, the RO Membrane should be treated with Antiscalants before the initiation of the process of Reverse Osmosis. Chemtex Speciality Limited has been in the foray of manufacturing a wide range of RO Antiscalant since they have ventured into the chemical industry in 1970. The range of RO Antiscalant they cater includes Low pH, High pH, Neutral pH, High Silica RO Antiscalant, etc.

When used continuously, RO Antiscalant, formulated by Chemtex, aids in ensuring beyond 80% reduction in scaling tendencies. RO Antiscalant efficiently helps in controlling Iron fouling by sequestration thereby reducing the frequency of membrane cleaning. It appears to be a very efficient antiscalant for waters with Langelier Saturation Index upto +2.7, Iron upto 1.4ppm in reject, Silica upto 175ppm (or mg/l), High SDI. RO Antiscalant aids in controlling the capacity of RO close to design, and assists in minimizing membrane cleaning cost and shutdowns. It accounts for effective scale inhibition with high recovery rate. It is effective at low chemical dosage thus appears to be economical.
