Reverse Osmosis (RO) Water Treatment Plant – 3000 GPD /500 LPH
Approx. Suitable for 600–1200 Persons
Product Overview
The 3000 GPD (approximately 500 LPH) Reverse Osmosis Water Treatment Plant is a commercial-grade potable water purification system designed to produce safe, hygienic, and high-quality drinking water for medium-scale daily consumption.
This RO system is engineered to remove high TDS, dissolved salts, heavy metals, harmful chemicals, bacteria, and viruses from borewell, tube-well, or municipal water sources. It is ideal for supplying purified water to schools, colleges, offices, factories, mosques, hostels, restaurants, hospitals, and residential communities serving around 600–1200 people, depending on usage pattern.
A 1252 FRP pressure vessel is used in the pre-treatment stage, allowing higher filtration media volume and better contact time, which significantly improves raw water conditioning and protects RO membranes for long-term stable performance.

System Components & Process Flow
Pre-Treatment Section
Raw Water Feed Pump
Supplies consistent flow and pressure to the system
Pressure Sand Filter – 1252 FRP Vessel
Removes sand, dirt, turbidity, and suspended solids
Activated Carbon Filter (ACF)
Eliminates chlorine, color, odor, and organic impurities
Protects the RO membrane from chemical damage
Micron Cartridge Filter (5–10 Micron)
Final fine filtration before the RO membrane
RO Purification Section
High-Pressure RO Pump
Generates the required pressure for membrane operation
RO Membrane Housing with RO Membrane(s)
Removes dissolved salts, heavy metals, bacteria, viruses, and microbes
Pressure Gauges & Flow Meters
Continuous monitoring of inlet pressure, permeate flow, and reject flow
Post-Treatment & Storage
RO Product Water Storage Tank (capacity as per site requirement)
UV Sterilizer / Ozone System (Optional but Recommended)
Final disinfection to ensure microbiological safety
Optional Polishing Filter
Enhances the taste and visual clarity of drinking water
Working Principle (RO Process)
Raw water first passes through sand, carbon, and cartridge filters to remove physical and chemical impurities.
Pre-treated water is then pressurized and passed through a semi-permeable RO membrane, which allows only pure water molecules to pass.
Permeate water is collected as drinking water, while reject water containing concentrated impurities is discharged.
Application Areas
Offices & corporate buildings
Factories & industrial units (drinking water supply)
Schools, colleges & training centers
Mosques, madrasas & religious institutions
Restaurants, canteens & food courts
Residential compounds & housing projects
Key Benefits
Produces safe and potable drinking water
Efficient removal of high TDS and chemical contaminants
Protects health by eliminating bacteria and viruses
1252 vessel ensures better pre-treatment efficiency
Improves water taste, odor, and clarity
Reliable system for medium to large user groups
Operation & Maintenance
Regular backwashing of sand and carbon filters
Periodic replacement of cartridge filters
RO membrane life is typically 2–3 years (based on water quality)
CIP (chemical cleaning) as per performance trend
Routine monitoring of TDS, pressure, and flow rates
Important Design Notes
Raw water testing (TDS, iron, hardness, turbidity, chlorine) is mandatory before final installation
An additional iron removal or softener unit may be required if the iron or hardness is high
Actual output and recovery depend on raw water quality
