Product Overview
Engineered for severe industrial salinity challenges, this high-TDS brackish water reverse osmosis system processes feed water from 3,000 mg/L to 10,000 mg/L total dissolved solids. By integrating high-pressure multi-stage pumps, high-rejection membranes, and automated chemical dosing, it overcomes high osmotic pressure to maintain a salt rejection rate above 99.2%. Built on a heavy-duty structural steel skid, it unifies pre-treatment, membrane separation, and PLC controls into a modular footprint to deliver continuous, high-purity water for heavy industry and mining operations.

Core Technology
Precision Antiscalant Dosing
Multi-channel pulse pumps inject scale inhibitors proportional to raw water flow to prevent silica and sulfate crystallization.
Concentration Polarization Control
Optimized spiral-wound feed spacers induce fluid turbulence, disrupting boundary layer salinity buildup.
Hydraulic Stress Balancing
Symmetrical headers ensure uniform pressure and flow velocity across parallel pressure vessels, preventing premature membrane telescoping.
Typical Applications
Mining & Mineral Processing: Desalinating high-salinity mine dewatering effluent for dust suppression and equipment cooling.
Oil & Gas Operations: Processing produced water and high-TDS groundwater for enhanced oil recovery or safe discharge.
Inland Municipal Water: Converting deep-well mineralized sources into compliant municipal drinking water.
Industrial Manufacturing: Supplying high-purity makeup water for high-pressure industrial boilers.
Operational Process Flow
Pre-Filtration: Multi-media and cartridge filters remove suspended solids and turbidity.
Pressurization: Vertical multi-stage pumps overcome high raw water osmotic pressure.
Separation: Polyamide composite membranes filter water molecules while retaining ions in the brine.
Post-Treatment: Permeate passes through pH adjustment or degassing as needed.
Hardware Configuration
Pumping & Filtration: Stainless steel high-pressure pumps with VFDs; FRP/steel pre-treatment vessels with pneumatic valves.
Membrane Array: 304/316L stainless steel pressure vessels with 8-inch high-pressure composite membrane elements.
Control Architecture: PLC with color touch screen interface and inline digital sensors for real-time monitoring.
