Below are the essential machines and equipment required to establish an RO Water Plant.
The purification process begins with storing raw water collected from sources such as:
A Raw Water Storage Tank ensures a continuous supply of water to the purification system.
A Raw Water Pump transfers water from the storage tank to the filtration system while maintaining the required pressure for smooth plant operation.
The Multi Grade Sand Filter removes suspended solids, sand, dirt, rust particles, and other large impurities from raw water.
This is the first stage of water filtration and helps protect downstream equipment from damage.
After sand filtration, water passes through the Activated Carbon Filter.
This filter removes:
It also improves the overall quality of water before it enters the RO Membrane.
If the source water contains high hardness, a Water Softener is installed before the RO system.
It reduces calcium and magnesium content, preventing scale formation on the RO Membranes and increasing their lifespan.
Before entering the RO Membrane, water passes through a Micron Cartridge Filter, which removes very fine suspended particles.
This protects the RO Membrane from clogging and improves purification efficiency.
The High Pressure Pump generates the pressure required for the Reverse Osmosis process.
Without sufficient pressure, the RO Membrane cannot effectively separate dissolved salts and impurities.
The RO Membrane is the heart of the entire purification system.
It removes:
This process produces clean and safe drinking water.
Many commercial plants also include a UV Sterilizer.
Ultraviolet light destroys bacteria, viruses, and microorganisms without using chemicals, providing an additional level of safety.
An Ozone Generator disinfects purified water and helps increase its shelf life, especially in bottled drinking water production.
Ozonation also helps maintain water quality during storage.
After purification, the treated water is stored in Food Grade Stainless Steel Storage Tanks before filling.
These tanks help maintain hygiene and prevent contamination.
Before filling, bottles and 20-litre jars must be cleaned properly.
A Bottle or Jar Washing Machine removes dust, dirt, and microbial contamination, ensuring hygienic packaging.
The purified water is filled into:
Automatic Filling Machines improve accuracy, reduce wastage, and increase production speed.
After filling, bottles are sealed using a Bottle Capping Machine.
Proper sealing prevents leakage and contamination while increasing product shelf life.
A Labeling Machine applies labels containing important information such as:
Professional labeling enhances brand identity and consumer trust.
For wholesale distribution, a Shrink Wrapping Machine bundles multiple bottles together for safer transportation and professional packaging.
The purification process in an RO Water Plant follows multiple stages to ensure safe drinking water.
Water is collected from a suitable source such as a borewell, municipal supply, or other approved source.
Water passes through the Multi Grade Sand Filter, where suspended solids, sand, and larger particles are removed.
The Activated Carbon Filter removes chlorine, odor, color, and organic impurities.
If hardness is high, water is softened before entering the RO system.
Fine suspended particles are removed using a Micron Cartridge Filter.
Water passes through the RO Membrane, which removes dissolved salts, bacteria, viruses, heavy metals, and other contaminants.
Purified water is further disinfected using UV Sterilization and Ozonation to ensure microbiological safety.
Purified water is stored in hygienic Stainless Steel Tanks before packaging.
Finally, the treated water is filled into jars, bottles, or pouches, sealed, labeled, and packed for distribution.
The land requirement depends on the plant capacity and production volume.
