Top Reverse Osmosis Plant (RO Plant) manufacturers in Pune | Shree Water Tech
SHREE WATER TECH is a leading Reverse Osmosis Plant Manufacturer, Supplier and Exporter based in Pune. A Reverse Osmosis Plant (RO Plant) is an advanced water purification system that uses semi-permeable membranes to reduce dissolved salts, minerals, contaminants, and other impurities from water. Reverse osmosis is widely used for producing purified water from municipal, borewell, brackish, surface, and industrial water sources.
RO technology works by applying pressure to feed water and forcing it through a specialized membrane. The membrane allows water molecules to pass while restricting many dissolved substances. The resulting streams are known as permeate and concentrate.
Depending on the application, an RO system can be combined with water softening, ultrafiltration (UF), activated carbon filtration, demineralization, disinfection, and post-treatment systems. Learn more about us.
What is a Reverse Osmosis Plant?
A Reverse Osmosis Plant is a water-treatment system designed to separate dissolved contaminants from water using pressure-driven membrane filtration.
In a conventional RO process, feed water is pressurized and supplied to the RO membrane. A portion of the water passes through the membrane as purified permeate, while the remaining stream carries concentrated contaminants away as reject or concentrate.
The main purpose of reverse osmosis is to reduce dissolved substances such as salts and minerals and produce water suitable for drinking, industrial processing, manufacturing, and other applications.
The actual removal performance depends on membrane selection, feed-water chemistry, pressure, temperature, recovery, and pretreatment.
How Does a Reverse Osmosis Plant Work?
As Reverse Osmosis Plant Manufacturers, Suppliers and Exporters based in Pune, an RO Plant we supply generally operates through the following sequence:
1. Feed Water Supply
Raw water is collected from the selected source and transferred to the RO pretreatment section using a suitable feed pump.
2. Pre-Treatment
Pretreatment reduces suspended solids, chlorine, hardness, and other substances that could affect membrane performance. Depending on the source water, this may include Pressure Sand Filter, Activated Carbon Filter, water softener, UF, or chemical dosing.
3. Cartridge Filtration
A cartridge filter provides fine particulate filtration before the high-pressure pump and membrane section. It helps protect the RO membranes from remaining suspended particles.
4. High-Pressure Pumping
The feed water is pressurized to the level required for the selected RO membrane and water chemistry.
5. Membrane Separation
Pressurized water enters the RO membrane assembly. Water passes through the membrane as permeate, while a concentrated stream containing a higher proportion of rejected contaminants leaves as concentrate.
6. Permeate Collection
The purified permeate is collected and transferred to a treated-water tank or post-treatment system.
7. Post-Treatment
Depending on the application, post-treatment can include UV disinfection, ozone, mineralization, pH correction, or additional polishing.

- Textile Industry: RO plants are used to produce low-TDS water for textile processing, dyeing, washing, and finishing operations. Treated water can help maintain consistent process conditions and support water-recycling programs.
- Chemical Industry: Chemical manufacturing facilities use RO systems where reduced dissolved solids are required for process or utility water. RO can also be incorporated into broader water-treatment trains with filtration and demineralization.
- Power and Utility Plants: RO is commonly used as a pretreatment stage for demineralized water and boiler-feed-water systems in power and utility applications. It helps reduce the dissolved ionic load before downstream polishing equipment.
Reverse Osmosis Plant Capacity
RO Plant capacity is commonly expressed in LPH (Litres Per Hour). The appropriate capacity depends on water consumption, required production, operating hours, feed-water availability, and recovery requirements.
Common system capacities include:
| Capacity | Nominal Production Rate |
|---|---|
| 50 LPH | 50 litres/hour |
| 100 LPH | 100 litres/hour |
| 250 LPH | 250 litres/hour |
| 500 LPH | 500 litres/hour |
| 1,000 LPH | 1,000 litres/hour |
| 2,000 LPH | 2,000 litres/hour |
| 3,000 LPH | 3,000 litres/hour |
For larger applications, industrial and municipal RO systems above 2,000 LPH can be engineered according to project requirements.
Actual permeate production depends on feed-water temperature, pressure, salinity, membrane condition, recovery rate, and pretreatment quality.
Factors to Consider When Selecting an RO Plant
The first consideration should be a detailed feed-water analysis. Important parameters include TDS, hardness, turbidity, pH, temperature, silica, iron, manganese, alkalinity, chlorine, and microbiological characteristics where applicable.
Other factors include required permeate quality, daily water demand, peak consumption, recovery target, available space, power supply, pretreatment requirements, membrane selection, concentrate management, automation level, and future expansion.
Selecting the system solely by nominal capacity can result in improper sizing if feed-water chemistry is not considered.
Reverse Osmosis Plant Cost
The cost of an RO Plant depends on its capacity, membrane configuration, feed-water quality, pretreatment requirements, automation, construction material, recovery target, and installation scope.
A domestic system has a different cost structure from a commercial or industrial RO plant because industrial systems require larger pumps, membrane assemblies, and pretreatment equipment, instrumentation, and control systems.
The overall project cost may include pretreatment equipment, pumps, membranes, membrane housings, filters, electrical panels, instrumentation, piping, storage tanks, installation, commissioning, and post-treatment equipment.
Operating costs should also account for electricity, filter replacements, membrane cleaning, chemicals, membrane replacement, and concentrate management.
RO Plant Installation & Maintenance
RO installation begins with site assessment and equipment positioning. Feed-water and product-water connections are established along with concentrate discharge or recovery arrangements.
Electrical connections, control panels, pumps, instruments, and automated valves are then commissioned and tested.
Routine maintenance includes:
- Replacing cartridge filters
- Monitoring inlet and outlet pressure
- Checking permeate flow
- Monitoring product-water TDS or conductivity
- Inspecting pumps
- Cleaning membranes when required
- Checking pretreatment equipment
- Inspecting valves and piping
- Calibrating instruments
- Monitoring recovery performance
Consistent pretreatment and timely membrane cleaning can help maintain stable RO performance.

FAQ's
Reverse Osmosis Plants are water-treatment systems that use semi-permeable membranes and applied pressure to separate water from many dissolved salts, minerals, and other contaminants.
The main purpose of RO is to reduce dissolved substances from water and produce a purified permeate stream suitable for the intended application.
RO systems can broadly be categorized according to application and feed-water characteristics, such as domestic RO, commercial RO, brackish-water RO, and industrial RO systems.
RO Plants are used for drinking-water purification, process-water treatment, industrial water production, desalination-related applications, and water-recovery systems.
RO provides very fine membrane separation and is widely used for dissolved-salt reduction. UF primarily removes suspended solids, colloids, and larger molecular contaminants, while NF provides intermediate separation and can reduce selected dissolved components.
