Question 1

Who supplies water treatment chemicals in bulk in Oman and the GCC?

Accepted Answer

Global Chemicals LLC stocks the full municipal and industrial water treatment range in Muscat — PAC (poly aluminium chloride, liquid 10–18% and powder 30%), aluminium sulphate, calcium and sodium hypochlorite, chlorine tablets (TCCA), caustic soda, soda ash, antiscalants, biocides, and flocculants — with same-day Muscat delivery, next-day Sohar/Nizwa, and scheduled GCC export lanes to the UAE and Saudi Arabia. Every batch ships with CoA and GHS SDS; JSRS registration covers supply to PDO and OQ water operations.

Question 2

PAC or alum — which coagulant should a water treatment plant use?

Accepted Answer

PAC (poly aluminium chloride) outperforms aluminium sulphate in most Gulf applications: it works across a wider pH window (5–9 versus alum's narrow 5.5–7.5), consumes far less alkalinity, produces denser faster-settling floc, and leaves lower residual aluminium — decisive advantages on Oman's alkaline, high-TDS source waters. Alum remains the lower-cost option for well-buffered waters with simple turbidity loads. Typical PAC dosing is 5–50 ppm as product depending on raw-water turbidity; jar testing confirms the optimum, and our technical team runs dose trials with customer samples.

Question 3

What chlorine dose is required for potable water disinfection?

Accepted Answer

Standard practice targets a free chlorine residual of 0.2–0.5 mg/L at the furthest point of the network. Breakpoint dosing depends on ammonia and organic load — typically 1–3 mg/L applied dose for treated water and up to 5+ mg/L for raw well water. Calcium hypochlorite 65–70% granules suit remote sites and tanker disinfection (1.5 g per 1,000 L gives roughly 1 mg/L); sodium hypochlorite 12.5% suits dosed systems with metering pumps; TCCA tablets provide slow-release residual in storage tanks. Use our online chlorine dosing calculator at /tools/dosing-calculator to convert between products and target residuals.

Question 4

Do you supply antiscalants and chemicals for desalination plants?

Accepted Answer

Yes — antiscalant formulations for RO seawater and brackish-water trains dosed at 2–5 ppm ahead of the membranes, plus the supporting chemistry: sodium metabisulphite for dechlorination, citric and sulphamic acid descalants, membrane cleaners, caustic soda and soda ash for post-treatment pH correction and remineralisation support, and calcium hypochlorite for intake shock dosing. We serve municipal desalination operators and private RO plants across Oman and export to GCC water utilities with full documentation.
