Water treatment chemicals encompass a broad portfolio of products essential for producing safe drinking water, treating industrial effluent, conditioning boiler and cooling systems, and maintaining desalination plant performance. Key product categories include antiscalants and scale inhibitors, coagulants and flocculants, pH adjustment chemicals, membrane cleaning agents, oxygen scavengers, and disinfectants such as chlorine, chloramine, and chlorine dioxide.

The UAE and Saudi Arabia operate the world's largest desalination capacities, with facilities like Ras Al Khair, Jubail, Jebel Ali, and Taweelah consuming thousands of tonnes of treatment chemicals annually. Beyond desalination, the region's expanding industrial base, mega-construction projects, and tightening effluent discharge regulations are increasing demand for sophisticated water treatment programmes. Treated sewage effluent (TSE) reuse is growing rapidly under sustainability mandates.

When sourcing water treatment chemicals, procurement teams should prioritise suppliers with demonstrated experience in the GCC's unique water chemistry, which includes high salinity, high temperature, and elevated biofouling potential. Request performance guarantees tied to measurable KPIs such as membrane flux maintenance, treated water quality, or blowdown reduction. Evaluate total cost of treatment per cubic metre, not just chemical unit price. Look for suppliers offering integrated service packages including monitoring, dosing equipment, and regular technical reporting.

Frequently Asked Questions — Water Treatment Chemicals

What antiscalants are used in SWRO desalination plants in the GCC?
GCC SWRO plants primarily use phosphonate-based and polycarboxylic acid-based antiscalants to prevent calcium carbonate, calcium sulphate, barium sulphate, and silica scaling on membranes. Product selection depends on the specific scaling risk identified through water analysis and projection software like ROSA or TorayDS. Most major antiscalant brands have local stock in the UAE and Saudi Arabia.
How large is the water treatment chemicals market in the UAE and Saudi Arabia?
The GCC water treatment chemicals market is valued at several billion dollars annually, driven by desalination, industrial water treatment, and wastewater reuse. Saudi Arabia alone operates over 30 desalination plants. Procurement opportunities exist across government utilities like SWCC, NWC, DEWA, and ADDC, as well as private industrial water treatment programmes. Tenders are typically issued through e-procurement portals.
Do water treatment chemical suppliers need specific approvals to supply government utilities in the GCC?
Yes, suppliers to government utilities must typically be registered as approved vendors. In Saudi Arabia, SWCC and NWC maintain approved vendor lists with specific qualification requirements. In the UAE, DEWA, ADDC, and SEWA have their own vendor registration processes. Products may need NSF/ANSI 60 certification for potable water contact and must comply with local health authority regulations.
What chemicals are used for CIP cleaning of RO membranes in the GCC?
RO membrane cleaning in GCC desalination and industrial plants typically uses alkaline solutions (sodium hydroxide at pH 11-12) for organic and biological fouling, and acidic solutions (citric acid or hydrochloric acid at pH 2-3) for inorganic scale removal. Specialty membrane cleaners with surfactants and chelating agents are used for stubborn fouling. Cleaning frequency depends on normalised performance data and is typically performed every 1-6 months.
