Reverse Osmosis (RO) Water Treatment Plant – 18000 GPD / 3000 LPH

Reverse Osmosis (RO) Water Treatment Plant – 18000 GPD / 3000 LPH

Approx. Suitable for 9600–12000 Persons

Product Overview

This high-capacity 18000 GPD (~3000 LPH) RO Water Treatment Plant is engineered for very large-scale potable water supply, capable of serving 9600–12000 users with consistent, safe, and reliable water output.

The system uses a 36×72 (3672) FRP pressure vessel for pre-treatment, providing exceptionally large media volume for superior turbidity removal and chemical conditioning. This ensures optimal feed water quality, protects RO membranes, and maintains steady performance even under extended peak-hour operations.

Ideal for large industrial zones, universities, hospitals, mega residential colonies, public water distribution hubs, and major religious complexes, this system combines robust pre-treatment, high-efficiency RO separation, and post-treatment options for a complete potable water solution.

System Components & Process

Pre-Treatment Section

1. Raw Water Transfer Pump

   • Provides consistent feed pressure and flow

2. Pressure Sand Filter – 3672 FRP Vessel

   • Removes sand, silt, turbidity, and suspended solids

3. Activated Carbon Filter (ACF)

   • Eliminates chlorine, odor, color, and organic contaminants

   • Prevents oxidative damage to RO membranes

4. Micron Cartridge Filter (5–10 Micron)

   • Ensures fine particulate removal before RO membranes

RO Separation Section

5. High-Pressure RO Pump

   • Delivers feed water at the required pressure for RO operation

6. RO Membrane Housings with High-Rejection Membranes

   • Effectively removes dissolved salts, heavy metals, bacteria, and viruses

7. Flow Meters & Pressure Gauges

   • Real-time monitoring of performance and safety

Post-Treatment & Storage

8. RO Product Water Storage Tank (size as per site design)

9. UV Sterilizer / Ozone Disinfection (Optional)

   • Final microbial safety barrier for potable water

10. Polishing Filter (Optional)

• Enhances taste, clarity, and acceptability

Working Principle

• Raw water is conditioned through sand and carbon filtration, removing physical and chemical stressors.

• Pre-treated water passes through RO membranes, allowing only purified water molecules to pass.

• Permeate water is collected for drinking, while reject water containing concentrated impurities is safely discharged.

Typical Applications

• Mega industrial complexes & factories

• Universities, colleges & large hostels

• Hospitals & healthcare campuses

• Large mosques & religious institutions

• Residential townships & community housing

• Public water supply stations

Key Advantages

• High-volume, continuous potable water production

• 3672 FRP vessel ensures maximum pre-treatment efficiency

• Reduces membrane fouling and pressure fluctuations

• Long membrane lifespan and stable performance

• Lower downtime and maintenance requirements

• Designed for large-scale institutional and community use

Operation & Maintenance

• Scheduled backwash of sand and carbon filters

• Cartridge filter replacement based on differential pressure

• RO membrane life is typically 2–3 years (feed water dependent)

• Periodic CIP cleaning to restore membrane efficiency

• Monitoring of TDS, flow, and operating pressures

Design & Selection Guidelines

• Raw water analysis (TDS, iron, hardness, chlorine, turbidity) is mandatory

• Pre-treatment (iron removal/softener) may be required, depending onthe  feed water quality

• Performance depends on adherence to operating & maintenance protocols

Standard Supply Scope

• Skid-mounted RO system with MS powder-coated frame

• 3672 FRP pre-treatment pressure vessel with graded filter media

• RO membranes with SS membrane housings

• High-pressure pump, flow meters & pressure gauges

• Cartridge filter housings & UV/ozone system (if included)

• Electrical control panel, valves, piping & fittings
