500 LPH RO Skid With Raw Water Pump
The 500 LPH RO skid delivers up to 500 litres per hour of clean, treated water. All components sit securely on a single steel frame, arriving fully assembled and ready for quick installation. This skid-mounted design reduces setup errors and ensures reliable performance for commercial and light industrial use.
The built-in raw water pump provides steady water from tanks, boreholes, or municipal sources, keeping the RO skid’s output stable and consistent.
Frame and Integrated Design of the 500 LPH RO Skid
This skid-mounted RO system mounts pretreatment units, pumps, membranes, and controls on a single frame. Factory assembly ensures proper alignment, reducing vibration and connection issues. The compact frame also makes transport, placement, and servicing simple.
Since the system comes pre-piped and pre-wired, setup is faster, saving labour and reducing installation time.
Pretreatment Stages for Protection
Before water reaches the RO membranes, it flows through pretreatment filters installed on the skid. These filters remove sediment, chlorine, and hardness, protecting membranes and the high-pressure pump. Pretreatment components include sand and carbon filters, a water softener, and a precision filter.
Components Mounted on the 500 LPH RO Skid
All key parts are mounted neatly on the skid frame:
- Raw water feed pump
- Sand and carbon pretreatment filters
- Water softener and precision filter
- High-pressure pump
- RO membranes for salts and impurities
- Manifolds, valves, and gauges
- Electrical control panel
This skid-mounted RO unit operates smoothly and remains organised.
Benefits of the 500 LPH RO Skid
The 500 LPH RO skid delivers reliable water output while remaining easy to operate. It handles varying feed water conditions, reduces maintenance, and its compact skid design saves space while keeping components accessible.
Applications
Ideal for guesthouses, hostels, workshops, small factories, and commercial facilities. Works with borehole, tank, or municipal water supplies. Its strong frame supports both drinking water and process water needs.
Maintenance Tips
Check pretreatment filters regularly and replace them when necessary. Monitor pressure gauges to identify issues early. Proper care ensures long-term, dependable operation.
