RO Services

As part of its sustainable and high-quality infrastructure initiative, Pallavi Green Project (OPC) Private Limited is implementing a Reverse Osmosis (RO) Water Purification System to ensure the consistent supply of high-purity water for domestic, commercial, or industrial applications.

RO systems play a critical role in treating hard water, brackish water, or water with high TDS (Total Dissolved Solids), making it safe and suitable for human use, process applications, and sensitive equipment.

Scope of Work

1. Raw Water Quality Assessment

• Analysis of feed water (TDS, pH, hardness, turbidity, etc.)

• Recommendation of pre-treatment stages based on input water parameters

2. Design and Engineering

• System Capacity: Based on daily water demand (e.g., 1000 LPH, 5000 LPH, etc.)

• System Type: Single pass or double pass RO depending on water quality requirement

• Recovery Rate: Designed for optimal water recovery (typically 60–75%)

3. Major Components

• Pre-Treatment Units:

  • Pressure Sand Filter (PSF)

  • Activated Carbon Filter (ACF)

  • Softener (if required)

  • Micron Cartridge Filter (5 & 1 micron)

• High Pressure Pump

• RO Membrane Assembly: TFC membranes suitable for low or high TDS

• Post-Treatment Systems: UV disinfection or pH adjustment, if needed

• Control Panel: Manual or PLC-based control with TDS monitoring and auto-flush

4. Installation and Commissioning

• Fabrication and erection of skids, pipework, and electricals

• Hydrotesting, flushing, and membrane installation

• Trial runs and performance testing with reporting

Standards and Compliance

• Conforms to:

  • IS 10500 (Drinking Water Standards)

  • WHO and BIS standards for potable water

  • RO system design as per industry best practices

Automation and Monitoring

• Online TDS meter and pressure gauges

• Flow indicators for permeate and reject streams

• Optional SCADA/PLC system for full automation with data logging

Operation and Maintenance

• Regular backwashing and chemical cleaning schedule (CIP)

• Membrane replacement cycle based on performance

• Optional AMC (Annual Maintenance Contract)

• User training and O&M manual provided

Applications

• Potable water supply for domestic use

• Process water for HVAC, flushing, or industrial use

• Makeup water for boilers, cooling towers, or water features

Environmental Considerations

• RO reject water disposal via soak pit or neutralization tank

• Option for RO reject reuse (gardening, toilet flushing) with secondary treatment

• Compliance with environmental discharge norms

Deliverables

• Detailed layout and P&ID drawings

• RO plant design calculations

• Test certificates and performance reports

• O&M manuals and training documentation

• Commissioning and handover report

Conclusion

The RO system implemented for Pallavi Green Project (OPC) Pvt. Ltd. is designed to deliver reliable, high-quality water with efficient resource use and environmental safety. It forms a vital component of the project's commitment to health, sustainability, and operational excellence.
