Name: Reverse Osmosis System
Brand: JX Filtration

Description

JX Filtration offers a full range of reverse osmosis systems from compact 0.5 t/h units to large industrial plants exceeding 100 m³/h, with flexible customization options to suit various feed water sources and purity requirements across electronics, pharmaceutical, food and beverage, chemical, and municipal applications—high-rejection, automated, and built for continuous operation.

A reverse osmosis system is a membrane-based water purification plant that uses pressure to force water molecules through a semi-permeable membrane while rejecting dissolved salts, colloids, organic matter, and microorganisms. The membrane pore size is approximately 0.0001 micrometers—about 5,000 times smaller than bacteria—enabling removal of 97%–99% of dissolved impurities and achieving water purity of 10–50 ppm or lower.

Working Principle

Pre-treatment: Raw water is first treated to remove suspended solids, residual chlorine, and hardness that could damage the RO membrane. A typical train includes multimedia filtration (quartz sand/anthracite, turbidity ≤1 NTU), activated carbon adsorption (chlorine removal >90%), and softening resin (hardness <17.1 mg/L as CaCO₃).
High-Pressure Membrane Separation: Pre-treated water is pressurized by a multistage centrifugal pump to the operating pressure required by the membrane—typically 10–25 bar for brackish water and 55–70 bar for seawater. Water molecules permeate through the membrane layers and are collected via the permeate spacer into the central tube, while dissolved salts, heavy metals, bacteria, and pyrogens remain on the feed side and are discharged as concentrate.
Post-Treatment (Optional): Depending on the target water quality, systems can be equipped with UV sterilization, EDI (electrodeionization) for deep desalination, or mineralization units to adjust final water characteristics.

Advantages

High desalination rate – Removes 97%–99% of dissolved salts, colloids, organic matter, and microorganisms; seawater-grade membranes achieve salt rejection up to 99.8%
No chemical additives – Physical separation process requiring no chemical dosing for basic desalination, environmentally friendly and safe
Complete pre-treatment integration – Multimedia filtration, activated carbon adsorption, and softening systems included to protect membranes and extend service life
Intelligent PLC control – Multi-parameter sensing for SDI, conductivity, and pressure; automatic chemical cleaning capability extends membrane life to over 5 years
Two-stage configuration available – Mid-stage booster pump increases recovery rate to 75% for higher efficiency
Modular skid-mounted design – Compact footprint with all components pre-piped and pre-wired for rapid installation and commissioning
Corrosion-resistant construction – 304 stainless steel tanks and piping standard; optional 316L for aggressive feed water
Customizable capacity and configuration – From 0.5 t/h pilot units to 100+ m³/h industrial plants, with single-pass or two-pass arrangements
