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.

    Core 4-Stage Filtration Process

    0.5 T/H 4-Stage Commercial RO Systems Compact Filtration 5
    ⚙️ Quartz Sand Filtration
    Removes suspended solids, sediment, rust, and large particulates, protecting downstream equipment and preventing clogging.
    0.5 T/H 4-Stage Commercial RO Systems Compact Filtration 6
    ⚙️ Activated Carbon Filtration
    Adsorbs residual chlorine, organic compounds, unpleasant tastes, odors, and color, improving water aesthetics and protecting the RO membrane from oxidation.
    4 (14)
    ⚙️ Precision Cartridge Filtration (5 μm)
    A 304 stainless-steel security filter that captures fine particulates down to 5 microns, serving as the final polishing barrier before the RO high-pressure pump and membrane.
    0.5 T/H 4-Stage Commercial RO Systems Compact Filtration 8
    ⚙️Reverse Osmosis (RO) System
    The core purification stage, fitted with 2 × 4040 high-efficiency RO membrane elements, removing up to 99% of dissolved salts, heavy metals, bacteria, and viruses to produce high-purity permeate.
    0.5 T/H 4-Stage Commercial RO Systems Compact Filtration 9
    ⚙️ Optional — Antiscalant Dosing System
    A metering dosing pump injects food-grade antiscalant into the RO feed water to inhibit CaCO₃, CaSO₄, and silica scaling, extending membrane service life and reducing cleaning frequency. Recommended for feed-water hardness above 3 mmol/L or for continuous-operation scenarios.
