500 LPH RO System with FRP Membrane Housings

The 500 LPH RO System produces up to 500 litres of purified water per hour, making it ideal for commercial and light industrial applications. It actively removes dissolved salts, suspended particles, and unwanted impurities, which ensures stable and consistent water quality.

Moreover, this industrial reverse osmosis unit uses durable components that support daily operation. As a result, it delivers reliable performance when treating borehole or municipal water with moderate TDS levels.

How the Reverse Osmosis System Works

First, feed water flows through pretreatment filtration, which reduces sediment and protects the RO membranes. Next, a high-pressure pump raises the water pressure to the required operating range.

After that, the system pushes water through RO membranes that separate salts and contaminants from clean product water. Meanwhile, pressure gauges and flow meters provide clear performance readings. Consequently, the system consistently produces low-TDS water while controlling reject flow efficiently.

Key Features and Benefits

  • Industrial reverse osmosis design ensures steady purification
  • FRP membrane housings resist corrosion and pressure stress
  • High-efficiency RO membranes improve salt rejection
  • Flow meters support accurate product and wastewater monitoring
  • Pressure gauges enhance safe system control
  • Compact stainless-steel frame simplifies installation

Installation and Maintenance Guidelines

To achieve optimal performance, installers should add suitable pretreatment before the RO system. Additionally, regular checks on pressure, flow rate, and water quality help maintain efficiency.

Over time, routine flushing and timely filter replacement extend membrane life while lowering operating costs.

Why Choose This Industrial RO Unit

This reverse osmosis system delivers a strong balance between capacity, efficiency, and durability. Therefore, it suits businesses that need dependable purified water without complex operation or heavy maintenance requirements.
