Reverse Osmosis Water Plant

Product Details:


Product Description

Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution, when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective" the membrane should not allow large molecules or ions to pass through the pores (holes), but should allow the solution (such as the solvent) to pass freely. Reverse osmosis is used to purify Water and remove salts and other impurities in order to improve the color, taste or properties of the fluid. RO or Reverse Osmosis is the best hyper filtration technique which clarifies the brackish water, seawater by removing the salt, fluids, discharge, dissolvable solvents, dyes, bacteria and other harmful constituents.

Treatment Process of RO plants:

Fluid systems RO plants work on the basis of Cross-filtration method, through which a percentage amount of feed water is rejected as the removal of solids during the filtration process. The whole process works through the combination of temperature and pressure. There are two elements while RO plants processing which are system recovery and product quality.

Working Procedure:

Reverse osmosis is water purification process in which pre-treated & filtered water is connected to the high-pressure pump where pressure is developed and fed to the RO membrane. Reverse Osmosis membranes work on the Cross flow Filtration method where the salts get rejected partially and deliver pure water. Purified water is referred to as product and waste water is referred to as concentrate or reject. The percent of water delivered as product is called the recovery. The ratio of recovery& output parameters depend upon the feed water quality, type of membrane, temperature and total RO unit design considerations.

Units in Reverse Osmosis Plant & its significance:

1) Raw Water Pump:

Raw water is water found in the environment that has not been treated and does not have any of its minerals, ions, particles, bacteria, or parasites removed. Raw water includes rainwater, groundwater from infiltration wells, and water from bodies like lakes and rivers. Raw water pump is way to transfer the water into the engine through a seacock fitting and pumping it through the engine's water jacket.

2) Pressure Sand Filter (PSF):

Here the water is filtered by Pressure sand filter for removal of suspended matters and turbidity.

3) Activated Carbon Filter (ACF):

Activated Carbon Filter is used to adsorb chlorine, organics, tri-halo methane (THM), taste, odor, and color from Water & Wastewater. Activated carbon is a charcoal that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. Activated carbon works via a process called adsorption having efficiency up to 90% whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate.

4) Micron Cartridge Filter (MCF):

These are pressure vessels Fitted internally with spun or pleated cartridge element which removes micron sized particles.  Cartridge filters require low maintenance and oversight. Use to remove microorganisms and biological chemical from water.

5) Anti scaling Dosing System:

It helps in preventing membrane from hardness.

6) High Pressure Pump:

High Pressure pump is provided for supplying the feed water to RO system at high pressure of 10- 12 kg/cm2.

7) Desalination system by RO membrane element:

Here Reverse Osmosis System rejects 90- 95% of Total Dissolved Solids.

8) Storage of treated unit:

To store treated pure water in tank

A single pass reverse osmosis system typically removes 97% of the total dissolved solids (TDS) and 95% of naturally occurring organics. The water recovery and average membrane flux usually ranges from 65 to 80% recovery and 14 to 18gfd respectively with both being dependent on the water chemistry.

1) Boiler water Treatment:

​Industries that rely on steam as a driving force for turbines, an energy source for heating, or product processing know that suspended and dissolved solids in a steam generator case scale and can lead to tube failure.  Poor boiler feed water quality increases energy consumption, reduces steam quality and purity, and can reduce both production rates and product quality.

2) Pharmaceutical Industry:

For pharmaceutical manufacturing, potable water supplied by a local municipality is not nearly pure enough.  Their product specifications require water free of bacteria and organics, with dissolved solids levels that are 10,000 times lower than those found in potable drinking water. The first step in reducing the suspended solids levels is reverse osmosis where 98% of the influent water salts can be removed.

3) RO systems for Industrial & mining waste retention ponds

A number of industries collect excess process water and rainwater contaminated by pollutants into catchment basins. During storm events these basins can be in danger of overflowing and creating an environmental impact by polluting nearby surface and groundwater. Portable reverse osmosis systems are used to reduce the volume of water in these basins, thereby allowing the facility to discharge clean unpolluted water while retaining the contaminants in the basin.

Other applications of Reverse Osmosis Plant:

1) Cooling Tower Water Treatment Plant
2) Utility & Process Water
3) Drinking Water
4) Horticulture for high end crop
5) Dialysis
6) Laboratories
7) Water For injection (WFI)
8) Water for electrical conductor circuits
9) Wastewater recycling
10) Zero Liquid discharge system
11) Food & Beverage processing, cosmetics industries.
