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.

Core 5-Stage Filtration Process
⚙️ Quartz Sand Filtration
Removes suspended solids, sediment, rust, and large particulates to protect downstream components and prevent clogging.
⚙️ Activated Carbon Filtration
Eliminates chlorine, organic compounds, unpleasant tastes, odors, and residual color, improving water aesthetics and protecting the RO membrane from oxidation.
⚙️ Antiscalant Dosing System
Precision-metered antiscalant injection prevents calcium carbonate, calcium sulfate, and silica scale formation on the RO membrane surface, maintaining consistent membrane performance and extending service life—an efficient alternative to ion-exchange softening for medium-hardness feed water.
⚙️ Precision Cartridge Filtration (5 μm)
A final polishing stage before RO, removing fine particulates and protecting the high-pressure pump and membrane elements from fouling.
⚙️ Reverse Osmosis (RO) System
The core purification stage, removing up to 99% of dissolved salts, heavy metals, bacteria, and viruses, producing high-purity water suitable for drinking, food processing, and industrial processes.

Benefits for Your Business
• High-Purity Water Output: RO technology ensures consistent water quality, suitable for drinking, laboratory, and industrial applications.
• Extended Equipment Lifespan: Softening and pre-treatment protect the RO membrane from scaling and fouling, reducing maintenance costs.
• Space-Efficient Design: The all-in-one skid package saves valuable floor space compared to separate units, with all components pre-assembled and pre-tested.
• Reduced Operational Cost: Antiscalant dosing eliminates the need for salt regeneration and resin replacement associated with traditional softeners, lowering ongoing consumable costs.
• Simple Operation: Push-button controls with clear gauge readings require minimal training, making the system accessible to operators without specialized water treatment expertise.
• Versatile Applications: Ideal for drinking water production, food & beverage processing, schools, hotels, small-scale manufacturing, boiler feed, and agricultural irrigation.
