Chlorine is cheap, effective, and completely unsuitable for RO membranes. It oxidises polyamide layers within days, silently destroying the very membranes it is meant to protect. Innova Corporate (India) manufactures a Peracetic Acid Based RO Disinfectant that solves this problem — a powerful oxidising biocide that kills microorganisms without attacking the membrane. It is engineered for the demanding water conditions of Doha's industrial and desalination sector.
The formulation is a synergistic blend of peracetic acid and hydrogen peroxide, stabilised for consistent performance in high-temperature, high-salinity environments. Unlike chlorine-based disinfectants, it decomposes into harmless by-products — water, oxygen, and acetic acid — leaving no toxic residue in the permeate. This makes it suitable for potable water, food and beverage, and pharmaceutical-grade RO applications. It is widely used in desalination plants, oil and gas facilities, and food processing units across Mesaieed, Ras Laffan and Al Wakrah.
Shock Dose: For immediate system disinfection, use a concentration of 5–10% v/v.
Continuous Dose: For round-the-clock microbial control, maintain a maximum of 2.5 ppm on feed water.
Sanitization Procedure: First sanitize the system with permeate water. Circulate the peracetic acid solution, followed by a flush with a High pH membrane cleaner for 30 minutes. Allow a soak time of 1–2 hours for deep penetration. Finally, flush the system thoroughly with permeate water before returning the plant to normal service.
Plants across Doha's industrial and utility sector rely on this disinfectant as a standard part of their RO hygiene programme. Common applications include:
Storage & Safety: Peracetic acid is a strong oxidiser. Store in original vented containers in a cool, well-ventilated area away from heat and direct sunlight. Please consult the Material Safety Data Sheet (MSDS) and Technical Data Sheet (TDS) for specific handling and safety protocols.
