Explore
Water Treatment & Desalination
Our company specializes in designing and constructing cutting-edge seawater desalination systems that provide sustainable solutions for communities around the world.
Explore
Minimum & Zero Liquid Discharge
High-recovery treatment trains that shrink or eliminate liquid discharge, turning brine into reusable water and solids.
Explore
Ultrapure Water
Water purified to the extreme — free of ions, organics, particles and gases — for semiconductors, pharmaceuticals and power generation.
Explore
PFAS & Emerging Contaminants
Separate and destroy “forever chemicals” and micropollutants to meet the new generation of water-quality limits.
Explore
Recycling & Reuse
By implementing advanced filtration, reverse osmosis, and other specialized techniques, we ensure that process water is purified for reuse in various manufacturing processes.
Explore
Waste-to-Energy
Turn the organic load in industrial wastewater and sludge into biogas, electricity and heat — cutting treatment costs and emissions at the same time.
ExploreNext-generation technologies
Built for the hardest water
Advanced brine concentration, high-recovery membranes, selective contaminant removal and advanced oxidation — pushing recovery further while cutting energy use and discharge.
OARO
Osmotically Assisted Reverse Osmosis
Membrane-based brine concentration that uses a saline sweep stream to take reverse osmosis far beyond its conventional osmotic-pressure limit.

HDH
Humidification–Dehumidification
Thermal desalination that evaporates water into a carrier air stream and condenses it as distillate — recovering clean water from extremely saline and difficult brines.
Learn more
CCRO
Closed Circuit Reverse Osmosis
High-recovery reverse osmosis in which the concentrate circulates in a closed loop and the pressure follows the rising osmotic pressure, cycle by cycle.
Learn more
SCR
Selective Contaminant Removal
Targeted removal of the specific contaminants that matter — without treating the entire water matrix.
Learn more
AOP
Advanced Oxidation Processes
A family of oxidation processes that generate highly reactive hydroxyl radicals to destroy persistent organic pollutants — selected to suit the water and the target compounds.
