Industrial Reverse Osmosis System – 750 Litres Per Hour
The industrial reverse osmosis system is designed to produce 750 litres of purified water per hour (4500 GPD) for continuous use in demanding environments. From the start, this system delivers stable performance for factories, laboratories, food processing plants, and commercial bottling operations.
Moreover, the unit is built on a durable stainless steel 304 frame, which helps prevent corrosion and extends service life. As a result, it remains reliable even under constant operating conditions. In addition, its compact skid-mounted design allows for simple installation while saving valuable floor space.

To ensure consistent performance, the industrial reverse osmosis system operates within the following feed water limits:
- Turbidity (SD): less than 5
- Total Dissolved Solids (TDS): below 2000 ppm
- Water temperature: +5 °C to 40 °C
- Free chlorine: 0 ppm
- pH range: 3 to 11
- Iron content: below 0.01 ppm
