Sodium Hypochlorite Supplier in Gujarat, India

Sodium hypochlorite (NaOCl, 10–12% available chlorine) from Drashti Chemicals supplies disinfection for municipal water, cooling tower bio-control, and ETP final treatment across Gujarat. Liquid bleach degrades with heat and time — Drashti rotates stock weekly and stamps production date on every drum so your store receives material with maximum available chlorine, not shelf-aged weak solution.

Grade selection: standard 10% for cooling towers and general disinfection; 12% for plants wanting lower shipping volume; low-salt grade when TDS addition to RO feed is a concern. Available chlorine degrades roughly 0.5–1% per week at 30 °C — size your tank to 2-week supply maximum. Request COA showing available chlorine, free alkali, and iron — iron catalyses decomposition.

Dosing guidelines: cooling tower blowdown control at 1–3 mg/L free chlorine residual; ETP final discharge disinfection at 5–10 mg/L contact dose with 30-minute retention; potable water 2–5 mg/L with dechlorination downstream. Never mix with acid — toxic chlorine gas release. Dose pumps must be PVC or PTFE — hypochlorite attacks SS316 above 500 ppm. Drashti provides dosing chart with first bulk order.

Packaging: 35 kg carboys, 50 kg HDPE drums, tanker loads for 5 KL+ monthly. MOQ one drum; bulk quote on request with scheduled tanker to Bharuch, Vadodara, and Ahmedabad. MSDS and COA per dispatch. Store shaded, below 25 °C, away from acids and organics. GST 24AGLPC6288M1ZX.

Hypochlorite vs. TCCA or calcium hypochlorite: liquid hypochlorite is ready-to-dose without dissolution; TCCA and Ca(OCl)₂ suit remote sites without liquid storage bunds. Hypochlorite vs. chlorine gas: hypochlorite eliminates gas cylinder handling risk but adds sodium load. For textile ETP, hypochlorite oxidises colour at high dose — pair with metabisulphite dechlorination before biological stage.
