Water challenges require integrated solutions.
No two facilities have exactly the same source water, process conditions, available space, water-quality targets or discharge requirements. GLS develops customized systems by combining proven treatment technologies with practical engineering, manufacturing and operational expertise. Our solutions cover the complete water cycle — from source-water treatment and purification to wastewater reuse and resource recovery.
Reliable fresh water from seawater and brackish sources.
Freshwater scarcity should not limit the performance or development of your facility. GLS designs and supplies reverse-osmosis desalination systems that convert seawater and brackish water into dependable supplies for drinking, hospitality, industrial processing and other applications.
Customized for the source and application
Our desalination packages are configured around:
- Raw-water salinity and quality
- Required production capacity
- Intended use of the treated water
- Recovery and energy-efficiency targets
- Available space
- Pretreatment requirements
- Post-treatment and remineralization needs
- Local operating conditions
SWRO systems treat high-salinity seawater through carefully engineered pretreatment, pressurization, membrane separation, control and post-treatment processes. Applications include coastal resorts, islands, industrial sites, marine facilities and locations with limited freshwater access.
BWRO systems treat groundwater or other sources with lower salinity than seawater. They can deliver high recovery rates and efficient production when properly matched to the raw-water characteristics.
- Intake and pretreatment
- Filtration or ultrafiltration
- Cartridge filtration
- High-pressure pumping
- Reverse-osmosis membranes
- Instrumentation and controls
- Cleaning systems
- Optional post-treatment
- Installation and commissioning
- Operations and maintenance
Safe, clean water designed for its intended use.
GLS combines pretreatment, ultrafiltration, reverse osmosis and advanced purification processes to remove suspended solids, dissolved contaminants and microorganisms. Our systems are designed for consistent water quality, efficient use of space and dependable operation.
Applications
- Potable water production
- Hotels and resorts
- Commercial buildings
- Villas and residential developments
- Industrial facilities
- Municipal and community water
- Offshore and remote operations
Depending on the source and target quality, a system may include:
- Screening
- Coagulation and clarification
- Activated filter media
- Ultrafiltration
- Reverse osmosis
- Nanofiltration
- Disinfection
- Remineralization
- Storage and distribution
Water engineered to protect production.
Water quality directly affects boilers, chillers, heat exchangers, membranes, production equipment and finished-product consistency. GLS designs industrial water systems that reduce scaling, fouling, corrosion, energy waste and unplanned maintenance.
Solutions include
- Boiler-feed water
- Cooling and chiller water
- Demineralized water
- High-purity process water
- RO pretreatment
- Industrial filtration
- Chemical dosing
- Condensate and water recovery
- System upgrades and optimization
Properly integrated treatment can help:
- Protect downstream assets
- Extend membrane and equipment life
- Reduce chemical consumption
- Improve heat-transfer efficiency
- Reduce backwash-water demand
- Maintain production reliability
- Lower lifecycle operating costs
Treat wastewater for compliance, reuse and long-term efficiency.
Industrial and municipal wastewater can contain suspended solids, fats, oils, grease, colour, organic matter, microorganisms, dissolved contaminants and other substances that require treatment before discharge or reuse. GLS integrates physical, chemical, biological and membrane processes into systems designed for each wastewater stream.
Treatment capabilities
- Screening
- Equalization
- Coagulation and flocculation
- Dissolved air flotation
- Biological treatment
- Membrane bioreactors
- Tertiary filtration
- Sludge thickening
- Sludge dewatering
- Disinfection
- Water reuse
DAF introduces micron-sized bubbles that attach to contaminants and lift them to the surface for removal. The process is particularly effective for suspended solids, fats, oils, grease, colour and algae. It can accelerate separation, reduce space requirements and improve downstream treatment.
MBR technology combines biological wastewater treatment with membrane filtration. The process produces high-quality effluent in a compact footprint and is well suited to wastewater recycling in hotels, commercial buildings, municipal systems and industrial facilities.
Turn treated wastewater into a dependable resource.
Water that was once discharged can often be treated for reuse in landscaping, cooling, process applications, cleaning and other non-potable uses. GLS develops reuse systems that reduce freshwater demand, lower discharge volumes and strengthen long-term water security.
A reuse system may integrate biological treatment, membrane filtration, reverse osmosis, disinfection and storage, depending on the intended application.
From wastewater treatment to resource recovery.
The future of water infrastructure is not limited to removing contaminants. It includes recovering water, nutrients, salts and energy that would otherwise be lost. GLS works toward a circular model in which wastewater becomes a source of useful materials and reclaimed water.
Recovery opportunities
Our engineers assess the technical and commercial potential of recovery as part of the broader treatment process.
Reduce sludge volume and simplify handling.
Sludge treatment is an essential part of efficient wastewater operations. GLS supplies thickening and dewatering systems designed to reduce sludge volume before transport, disposal or further processing.
Our enclosed thickening systems reduce volume prior to dewatering. They are designed for straightforward operation, reliable performance and cleaner working conditions.
GLS dewatering units remove water from sludge to make it easier and more cost-effective to handle, transport and dispose of. Applications include municipal and industrial wastewater-treatment facilities.
