    Product Overview

    Liquid bleach and disinfectant for water purification.

    Detailed Description

    Sodium Hypochlorite supplier in Oman - Global Chemicals LLC provides high-quality liquid chlorine for water treatment plants, swimming pools, and industrial facilities in Muscat, Sohar, Salalah. Our sodium hypochlorite ensures effective disinfection with reliable delivery and technical support throughout Oman. Sodium hypochlorite is the most widely used disinfectant in Oman's water treatment infrastructure — applied in PAEW municipal water treatment plants, industrial water treatment, swimming pools, and food processing sanitisation across the country. At 12–15% available chlorine, bulk sodium hypochlorite is dosed by metering pumps into treatment plant clearwells, distribution system boosters, and process water systems. In Oman's extensive desalination infrastructure, sodium hypochlorite is used for pre-treatment biocide dosing to prevent biofouling of RO membranes. Global Chemicals LLC supplies sodium hypochlorite in 25L jerricans, 200L HDPE drums, 1,000L IBC containers, and bulk tanker. On-site hypochlorite generation systems (electrochlorination) available for large-volume users. Technical grade supplied with chlorine assay certificate. Delivery to all Oman governorates.

    Frequently Asked Questions — Sodium Hypochlorite (Municipal Grade)

    Municipal water treatment plants in Oman, including PAEW-operated facilities, use sodium hypochlorite at 12–15% available chlorine for bulk dosing. This concentration is dosed at 0.5–2 mg/L residual chlorine in finished water. Swimming pools typically use 5–8% available chlorine. Industrial applications such as cooling tower biocide dosing use 10–12% grade. In Oman's high-temperature climate (up to 45°C ambient), hypochlorite degrades faster than in temperate climates, so storage time should not exceed 30 days after delivery for maximum potency. Global Chemicals LLC supplies the 12–15% grade with a chlorine assay certificate for every batch.

    Sodium hypochlorite is dosed using chemical metering pumps (peristaltic or diaphragm type) calibrated to inject the correct volume of solution into the treated water stream. In Oman's PAEW water treatment plants, dosing occurs at the clearwell outlet to achieve a minimum 0.2 mg/L free residual chlorine at the point of entry to the distribution network, in accordance with Oman's potable water standards. Larger plants use automated chlorine analysers with feedback control to maintain target residual levels. The 12–15% grade is preferred over dilute solutions (1–5%) because it reduces storage tank volume and pump running time while minimising the sodium content added to finished water.

    Sodium hypochlorite (12–15%) degrades at approximately 10–15% per month at 25°C, but degradation accelerates sharply above 30°C — reaching 20–25% per month at Oman's typical summer ambient temperatures of 38–45°C. Best practice in Oman is to use hypochlorite within 21–30 days of manufacture, store in shaded, cool conditions away from direct sunlight, and keep storage tanks topped up to minimise air exposure. Translucent or UV-resistant HDPE storage tanks are preferred. Global Chemicals LLC supplies fresh-assayed hypochlorite produced from recent electrochlorination runs, with the manufacture date and chlorine assay certificate on each delivery note.

    Global Chemicals LLC supplies sodium hypochlorite in 25L jerricans, 60L HDPE drums, 200L HDPE drums, and 1,000L IBC containers for routine industrial and commercial accounts. Bulk tanker delivery (5–20 tonne loads) is available for major water treatment plants, large industrial facilities, and municipal contractors in Muscat, Sohar, Salalah, and Duqm. All containers are food-contact-grade HDPE compatible with hypochlorite's high pH. Drum exchange programmes are available for regular accounts. Delivery is available to all Oman governorates. Export to UAE and GCC markets on request.

    Yes. Sodium hypochlorite at the correct dosage is approved for drinking water disinfection worldwide, including under Oman's national potable water standards and WHO guidelines. The key requirement is maintaining residual chlorine within the range of 0.2–0.5 mg/L in distributed water — sufficient to kill pathogens while remaining below the taste threshold (typically above 0.6 mg/L). The main by-products of concern are trihalomethanes (THMs), formed when chlorine reacts with naturally occurring organic matter. In Oman's desalinated water supply, which has very low organic matter content, THM formation is minimal. The product supplied must be food-grade or potable water grade with NSF or equivalent certification.
