Reverse Osmosis Systems
Reverse Osmosis Systems are high-precision water purification solutions that deliver deep water filtration for residential and light commercial use. Reverse Osmosis Systems rely on professional RO membrane filtration technology to thoroughly filter tap water, effectively removing fine sediment, heavy metals, residual chlorine, viruses and bacteria that ordinary filters cannot intercept, producing pure, safe drinking water for daily cooking and drinking.
These systems adopt a complete multi-stage filtration structure combined with precise water flow control, ensuring thorough purification without compromising water quality stability. Built with reliable food-grade materials and fully sealed pipelines, they effectively prevent secondary pollution and ensure long-term hygienic operation. The integrated structural design is compact and easy to install, with user-friendly filter replacement that simplifies daily maintenance work for ordinary households.
Reverse Osmosis Systems adapt to standard household water pressure and voltage with stable water purification flux. The high-quality RO membrane ensures accurate filtration precision and long service life, fully complying with international drinking water standards. Most models feature intelligent water shutoff and filter reminder functions, bringing safe, efficient and worry-free water purification for long-term home use.

Skid-mounted 3-Stage  Softening Commercial RO Systems
This compact, skid-mounted three-stage water softening & pre-treatment system is built for reliable continuous or scheduled operation. It integrates three independent filter tanks on one common skid: quartz sand filter, activated carbon filter, ion exchange softener. This all-in-one pre-treatment unit effectively removes sediment, rust, chlorine, organics and water hardness, protecting downstream RO, boilers, heat exchangers and pipelines from scaling and fouling.

It is widely used as pre-treatment for reverse osmosis systems, boiler feed water, circulating water, hotel & domestic water, food processing, light industry and commercial water supply projects. Flow rate and tank material are fully customizable to match your raw water conditions and project capacity requirements.
0.5 T/H Two-Stage Industrial RO Systems Water Purification
This compact, skid-mounted water treatment system is engineered for 0.5 m³/h (500 L/h) rated permeate flow, built for reliable continuous or scheduled operation. Combining pre-treatment (quartz sand, activated carbon, ion-exchange softening), precision filtration, and two-stage reverse osmosis (RO) into a single integrated unit, it delivers ultra-high-purity water with conductivity as low as 2–10 μS/cm, ideal for laboratory, pharmaceutical, food & beverage, electronics, and high-purity industrial applications.

Perfect for facilities requiring consistent, high-quality purified water with low dissolved solids—such as laboratories, dialysis centers, cosmetics manufacturing, bottled water production, and boiler feed systems—the system ensures reliable, ultra-pure water on demand.
3 T/H Reverse Commercial RO Systems Water Treatment
This compact, skid-mounted water treatment system is engineered for 3 m³/h (3,000 L/h) rated permeate flow, built for reliable continuous or scheduled operation. Combining five core stages—quartz sand filtration, activated carbon treatment, antiscalant dosing, precision filtration, and reverse osmosis (RO)—into a single integrated unit, it delivers high-purity water ideal for commercial, light industrial, food & beverage, and boiler feed applications.

Perfect for facilities requiring a steady supply of purified water, such as drinking water plants, food processing workshops, schools, hotels, and industrial manufacturing lines, the system ensures consistent, high-quality water on demand.
0.5 T/H 4-Stage Commercial RO Systems Compact Filtration
This compact, skid-mounted water treatment system is engineered for a rated permeate flow of 0.5 m³/h (500 L/h). It integrates four core treatment stages—quartz sand filtration, activated carbon adsorption, precision cartridge filtration, and reverse osmosis (RO)—into a single mobile frame. An optional antiscalant dosing system can be added to protect the RO membranes against mineral scaling, making the system versatile for municipal tap water, groundwater, and lightly brackish water sources.

Ideal for small commercial, light industrial, laboratory, and drinking-water applications, the system delivers consistent high-purity water with fully automated operation and minimal operator attention.
1 T/H Fully Enclosed Water Purification Commercial RO Systems
This fully enclosed, cabinet-type water treatment system is engineered for a rated permeate flow of 1 m³/h (1,000 L/h), built for scheduled and non-continuous operation. Housed in a 304 stainless steel cabinet with lockable doors and mobile casters, the unit integrates pre-treatment and reverse osmosis (RO) into a single, compact footprint.

The standard 4-stage configuration combines quartz sand filtration, activated carbon adsorption, PP cartridge filtration, and RO. A simplified 2-stage configuration (PP cartridge + RO) is available for good-quality municipal feed water, while pre-treatment can be further customized for challenging source water.

An integrated pressure tank stabilizes system pressure and delivers purified water on demand, while the intelligent RO controller with digital display, pressure gauges, and rotameters provides real-time monitoring and fully automated operation. The enclosed design protects all internal components from dust, moisture, and unauthorized access
1000LPH Compact Two-Stage Filtration Commercial RO Systems
This compact skid-mounted PP + RO water treatment system has a rated capacity of 1m³/h (1000 L/h), designed for intermittent and scheduled operation. It adopts a two-stage purification process: PP security filtration followed by reverse osmosis (RO). The simplified structure is built for users with relatively good raw water quality, to produce stable high-purity water for small commercial, light industrial and laboratory applications.

It is well suited for sites with fixed daily operating hours, such as cafes, small workshops, schools and boiler feed water systems, supplying purified water on demand.
500LPH Compact Two-Stage Commercial RO Systems Filtration System
