Chemicals and Consumables
The right chemicals and consumables, supplied consistently and applied correctly, are what keep a water treatment system performing to design specifications. GWT supplies a full range of process chemicals and consumables for water and wastewater treatment systems across the UAE and MENA region.
Consistent Supply. Correct Application. Sustained Performance.
Water and wastewater treatment systems are process-dependent. Every stage of treatment relies on the right chemical being available in the right quantity at the right time. A gap in supply, an incorrect specification, or an incompatible product can disrupt treatment performance, accelerate equipment wear, and put regulatory compliance at risk.
GWT supplies chemicals and consumables that are selected and verified for compatibility with specific system types, source water conditions, and treatment objectives. Technical guidance on dosing rates, handling, and storage is provided alongside supply to ensure correct application throughout the system’s operational life.
Supply is available on an as-needed basis or through scheduled delivery agreements structured around the client’s consumption patterns and storage capacity.
Process Chemicals
Antiscalants Scale formation on reverse osmosis membranes is one of the primary causes of reduced system output, increased energy consumption, and shortened membrane life. GWT supplies antiscalants formulated for seawater, brackish water, and high-salinity applications. Products are selected based on source water chemistry and system recovery rates to provide effective scale inhibition without over-dosing or chemical waste.
Coagulants and Flocculants Used in pre-treatment and wastewater treatment processes to aggregate suspended solids and colloidal particles for removal by sedimentation or filtration. GWT supplies both inorganic coagulants and polymer-based flocculants suited to a range of source water types and treatment configurations. Correct coagulant and flocculant selection reduces turbidity load on downstream membranes and improves overall treatment efficiency.
Biocides Biological fouling on membranes and within distribution systems reduces treatment performance and creates compliance risks. GWT supplies oxidising and non-oxidising biocides for dosing into feed water streams and for use in clean-in-place procedures. Products are selected for compatibility with membrane materials and system metallurgy to prevent equipment damage during application.
pH Adjustment Chemicals Maintaining correct pH across treatment stages is critical for process efficiency, membrane protection, and compliance with discharge standards. GWT supplies acids and alkalis for pH correction in pre-treatment, post-treatment, and wastewater neutralisation applications. Products are available in formulations suited to both continuous dosing and batch adjustment requirements.
Cleaning and Membrane Cleaning Chemicals Membrane performance declines over time due to scaling, fouling, and biological deposits. Scheduled clean-in-place procedures using the correct cleaning chemicals restore membrane flux and rejection rates, extending service life and maintaining output quality. GWT supplies acid cleaners, alkaline cleaners, and specialised membrane cleaning formulations compatible with the membrane types in the client’s system.
Disinfection Chemicals Used in post-treatment disinfection for potable water systems and in wastewater treatment prior to discharge or reuse. GWT supplies sodium hypochlorite, chlorine dioxide, and other disinfection agents for dosing into treated water streams. Products are supplied with technical guidance on dosing rates and residual targets to meet applicable water quality standards.
Defoamers and Antifoaming Agents Foam formation in biological treatment systems and effluent treatment processes interferes with aeration, settleability, and overall process performance. GWT supplies defoaming agents compatible with the biological and chemical processes in use at the client’s facility.
Neutralisation and Precipitation Chemicals Used in effluent treatment for pH correction, heavy metal precipitation, and chemical oxygen demand reduction prior to discharge. GWT supplies lime, caustic soda, ferrous sulphate, and other reagents for effluent neutralisation and treatment in industrial and manufacturing applications.
Consumables
Membrane Elements RO, nanofiltration, and ultrafiltration membrane elements are the core separation components in pressure-driven treatment systems. GWT supplies replacement membrane elements compatible with the pressure vessels and system configurations in use at the client’s facility. Elements are sourced from verified manufacturers and selected based on the specific feed water chemistry, recovery targets, and output quality requirements of the system.
Filter Cartridges Cartridge filters protect downstream membranes by removing particles and suspended solids from the feed stream. GWT supplies cartridge filters in a range of micron ratings and configurations to suit the pre-treatment requirements of different system types. Regular cartridge replacement on schedule prevents bypass of particles that cause membrane fouling and reduces the frequency of membrane cleaning cycles.
Filter Media Sand, anthracite, activated carbon, and other filtration media used in multimedia filters, activated carbon filters, and iron removal filters. GWT supplies replacement media for scheduled media changes and for systems requiring media top-up or replacement following backwash analysis.
UV Lamps UV disinfection systems require periodic lamp replacement to maintain the UV dose required for effective pathogen inactivation. GWT supplies replacement UV lamps compatible with the UV systems installed at the client’s facility. Lamp replacement on the recommended schedule ensures consistent disinfection performance and avoids compliance risk from reduced UV output.
Dosing Pump Diaphragms and Tubing Dosing system components including diaphragms, tubing, and injection quills are wear items that require periodic replacement. GWT supplies compatible replacement components for the dosing systems in use across its supported installations, reducing the risk of dosing failures and chemical leaks.
Why Source Chemicals and Consumables Through GWT
Verified Compatibility All chemicals and consumables supplied by GWT are selected for compatibility with the specific system, source water, and treatment process. Incompatible products can damage membranes, reduce process efficiency, and create compliance risk.
Technical Guidance Included Supply is accompanied by dosing recommendations, handling guidance, and safety data. GWT’s technical team is available to support correct application and to adjust dosing recommendations when source water conditions or system performance change.
Local Stock and Fast Delivery GWT maintains local inventory of high-demand chemicals and consumables across the UAE and MENA region. This reduces lead times, eliminates long supply chain delays, and ensures facilities are not left without critical materials.
Scheduled Supply Agreements Clients who prefer not to manage procurement independently can structure scheduled supply agreements with GWT. Deliveries are planned around consumption patterns and storage capacity, ensuring continuous availability without overstocking.
