Chlorine management in Kerala is more complicated than in most Indian states, because the water itself changes character through the year. During the monsoon months, surface water sources across the Western Ghats carry heavy organic loads — leaf litter, soil particles, microbial matter washed down by rainfall. Municipal treatment plants respond by raising chlorine doses to maintain disinfection, sometimes pushing residual chlorine in the distribution network above 2 ppm. In the dry months, the same sources drop to lower organic loads and chlorine residuals fall accordingly. For industrial RO plants drawing on municipal supply in Kochi, Trivandrum, Kozhikode or Kollam, this seasonal swing means the dechlorination requirement changes month to month, and a fixed dosing routine that works in January may fail badly in July. Innova Corporate (India) supplies RO Dechlorination Chemical in Kerala formulated for this kind of variability — a stabilized liquid that neutralizes free chlorine and chloramines on contact, across a wide range of feed chlorine levels.
The stakes in Kerala are particularly high because many of the state's industrial RO plants serve sensitive downstream processes. Seafood processors in Kochi and Alappuzha exporting to EU and US markets, dairy plants in Thrissur and Ernakulam running continuous CIP cycles, pharmaceutical units producing purified water for sterile manufacturing — for all of these, a single chlorine breakthrough that damages the TFC membrane is not just a maintenance cost. It shows up as falling rejection rates, rising permeate TDS and quality failures that can trigger batch rejections and regulatory consequences. Polyamide membranes that contact free chlorine above 0.1 ppm for sustained periods suffer irreversible oxidation, and the damage only becomes visible weeks later when performance has already drifted. Dechlorination done properly, with a chemistry that reacts reliably and completely, is the only way to prevent this outcome.
What makes our formulation practical for Kerala conditions is its stability in warm, humid ambient temperatures. Sodium bisulfite powder, the conventional choice, loses reducing strength over time and is difficult to dose accurately in variable feed conditions. Our stabilized liquid holds full activity across its shelf life and reacts with chlorine almost instantaneously, so the dechlorination step keeps pace with whatever chlorine level the municipal supply delivers. Plants in coastal districts where saline intrusion complicates feed water chemistry also benefit from the formulation's tolerance to elevated TDS — the reaction proceeds cleanly without the interference that affects simpler reducing agents.
The dosage depends on the residual chlorine levels and contact time. Typically, the dosage ranges from 3 ppm to 15 ppm for Kerala water conditions.
Always wear proper safety gear, including splash goggles, lab coats, gloves, and vapor respirators. In case of skin contact, wash immediately with water. Store in original containers in a cool, dry place at your Kerala facility, away from direct sunlight and heat sources. Recommended storage temperature is between 5°C to 40°C. Keep containers tightly sealed when not in use, and store away from incompatible materials such as strong oxidizers. Refer to the MSDS for comprehensive safety data.
*Note: As a company policy, Innova Corporate recommends consulting our service engineers in Kerala for precise dosage requirements based on your specific water chemistry. The product has a shelf life of 12 months from the date of manufacturing when stored under recommended conditions.
