Reverse osmosis (RO) is a membrane-technology filtration process for removing several types of large molecules and ions from solutions. During the process, it applies pressure to the solution when it is on one side of selective membrane. The solute retains on the pressurized side of the membrane and the pure solvent passes to the other side. The membrane must allow the solution to pass freely through the pores, but not large molecules or ions.
Reverse osmosis purifies water and removes salts as well as other impurities to improve its taste, color, taste and properties. This hyper filtration technique removes dyes, salt, dis solvable solvents, and harmful constituents from the brackish water, seawater.
Types of RO systems
The RO plant/ system is divided into three categories according to the use and market requirements:
- Residential RO plant/ system
- Industrial RO plants/ system
- Commercial RO plants/ system

Our range of RO systems include those systems that are designed and engineered for small lab applications, medium sized commercial applications, large industrial applications, and trailer-mounted mobile systems for emergency and temporary applications. The continued research & development and standard product development devoted to RO system engineering and many installations around the country made our customers put faith in EFPL for their demanding liquid separation and purification requirements making use of RO technologies. The RO plant does not remove natural nutrients from the water and maintain its health. RO systems are also customized to make them suitable for marine applications. These systems purify a large amount of water at once.
Treatment Process of RO plant:
Fluid systems RO plant works on Cross-filtration method in which a percentage of water is rejected in the filtration process while removing the solids. The complete process combines pressure and temperature. In the RO plant processing, there are two elements, product quality and system recovery.
Reverse osmosis (RO) is water purification process in which pre-treated and filtered water is connected to the high-pressure pump that develops pressure and fed it to the RO membrane. RO membrane works on the Cross flow Filtration method that partially rejects the salts and delivers pure water. Purified water is regarded as product and waste water is regarded as concentrate or reject. The amount of water delivered as a product is known as the recovery. Quality of feed water, membrane type, temperature, and complete RO unit design are some of the factors that are considered to determine the ratio of recovery & output parameters.
Units in RO Plant & its significance:
Raw Water Pump:
Raw water is untreated water found in the environment and does have ions, bacterial, minerals, particles, and parasites. Raw water is ground water and rainwater. Raw water pump is used for transferring water into the engine through a seacock fitting and pumping it through the water jacket of the engine.
Pressure Sand Filter (PSF):
Pressure sand filter is used to filter the water and remove suspended matters and turbidity.
Activated Carbon Filter (ACF):
The water and wastewater are filtered by the Activated Carbon Filter and odor, taste, color are improved. Charcoal is treated with oxygen to form activated carbon that has millions of tiny pores between the carbon atoms. It works via adsorption process that has efficiency up to 90% whereby pollutant molecules in the liquid to be treated are collected inside the pore structure of the carbon substrate.
Micron Cartridge Filter (MCF):
The low maintenance cartridge filter has pressure vessels fitted internally with spun/ pleated cartridge element that removes micron sized particles. It removes biological chemical and microorganisms from water.
Anti scaling Dosing System:
It is designed to prevent membrane from hardness.
High Pressure Pump:
- High Pressure pump supplies feed water to RO system at a pressure of 10- 12 kg/cm2.
- Desalination system by RO membrane element:
- RO system removes 90- 95% of Total Dissolved Solids.
Storage of treated unit:
It stores treated pure water.
RO system removes 97% of total dissolved solids (TDS) and 95% of naturally occurring organics in a single pass. The water recovery and average membrane flux ranges from 65 to 80% recovery and 14 to 18gfd respectively. The water recovery as well as membrane flux are dependent on the water chemistry.

Boiler water Treatment:
Industries that rely on steam as an energy source, a driving force understand that dissolved and suspended solids in a steam generator causes scale and lead to equipment failure. Poor feed water quality of increases energy consumption, and reduces stream purity & quality and results in reduced product quality and production rates.
Water from local municipality is not ideal for pharmaceutical manufacturing. Water free of bacterial and organics dissolved solids levels that are 10,000 times lower than those in potable drinking water is suitable for the product specifications. RO is the first step in reducing the suspended solids levels, in which 98% of the influent water salts are removed.
RO systems for Industrial & mining waste retention ponds
Industries collect pollutants contaminated rain water and excess process water into catchment basins. The storm events can cause these basins to overflow and pollute nearby surface water and ground water. Portable reverse osmosis systems can efficiently reduce the volume of water in these basins and allow the facility to discharge clean unpolluted water while retaining the contaminants in the basin.
Other applications of Reverse Osmosis Plant:
- Water For injection (WFI)
- Water for electrical conductor circuits
- Wastewater recycling
- Zero Liquid discharge system
- Cooling Tower Water Treatment Plant
- Utility & Process Water
- Drinking Water
- Horticulture for high end crop
- Food & Beverage processing, cosmetics industries.
