500LPH Compact Two-Stage Commercial RO Systems Filtration System
This compact skid-mounted PP + RO water treatment system has a rated capacity of 0.5m³/h (500 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.

Core 2-Stage Filtration Process
⚙️ PP Precision Cartridge Filtration
The pre-treatment protection stage. The PP filter cartridge intercepts suspended solids, sediment, rust and fine particles in raw water, to prevent large contaminants from entering and damaging the RO membrane, reducing the risk of membrane fouling.
⚙️ Reverse Osmosis (RO) System
The core purification stage. It removes up to 99% of dissolved salts, heavy metals, bacteria and viruses from the feed water, delivering consistent high-purity water for drinking, laboratory analysis and industrial production processes.
