Reverse Osmosis (RO) is a process of physical separation of dissolved solids and minerals present in water. This technology uses the principle of osmosis, wherein the mineral concentration of raw water is reduced by applying high pressure through a semi-permeable membrane.
Water is passed through following different stages for process of filtration & separation in packaged drinking water plant process.
To Control Micro-Organism in raw & treated water, To remove algae from raw Water.
To remove suspended matter from the water. By means of Multi size Graded sand filled in the Vessel of stainless steel material. Which is natural process of filtration adopted by the nature.
To remove Color, Odor and Smell from the water. By means of using Activated Natural carbon. By absorbing contaminated particles of Oil & Grease from the raw water. To control the BOD & COD in the raw water.
To prevent the desalting element from scale deposition.
To remove the micron particles from the raw water. By means of using disposable candles having Perfect micron size of porosity for filtration.
To create the osmotic pressure in raw water. By using pump.
To desalt the raw water i.e. to reduce the total dissolve solids. By using Semi permeable Membrane filter elements, Where ion filtration process is carried out by applying pressure in the water. So finally we will get Low salt water with low total dissolve solids and High purity. Here will Have to drain the water at one side to Wash the Membrane filter elements continuously because of filtration process there is nothing to be polluted in the system.
To remove back pressure in R.O. Membrane elements. It is only storage of the treated Water.
To filter the water from 1 micron to 0.2 microns to achieve the crystal clear filtered mineral water.
To kill the bacteria from fine water.
Finally healthiest bacteria free ,crystal clear and with required Quantity of ions , purified & bacteria free drinking water will be send to packing.
