| REVERSE OSMOSIS PLANT |
Reverse Osmosis is a high pressure membrane process that rejects practically all undissolved and dissolved impurities present in water. The permeate dissolve in very low concentration in organic salts. In order to understand the process of reverse osmosis we need to look first at the process of osmosis.
Osmosis is a natural process involving fluid flow across a semi permeable membrane barrier. Plant and animal cells are covered on the outside by a semi permeable membrane that allows water and nutrients to permeate into the cell and rejects macro molecule. The process is selective in the sense that the solvent passes through the membrane at a faster rate than the dissolved solids. The difference of passage rate results in solvent solids separation. The direction of solvent flow is determined by its chemical potential, which is a function of pressure, temperature, and concentration of dissolved solids. |

Application of an external pressure to the salt solution side equal to the osmotic pressure will also cause equilibrium. Additional pressure will raise the chemical potential of the water in the salt solution and cause a solvent flow to the pure water side, because it now has a lower chemical potential. This phenomenon is called reverse osmosis.
We design and manufacture the Reverse osmosis plant according to the need for tap water, brackish water & sea water application. The production range starts from 100 LPH (Liter per hour) to 100 M3 per hour for 400 TDS to 45,000 TDS.
- Produce high-quality dematerialized water
- Most modern membrane technology
- Modular design
- Low water-rejection rate
Low operational and maintenance costs Reverse Osmosis manufactured plants are used to produce high-quality dematerialized water, especially where the client looks to minimize the use of chemicals which are the regenerates associated with the more conventional dematerialized ion exchange process. R O Plant is used extensively in the food and beverage industry (especially the brewing industry), pharmaceutical and the electronics industries. uses a computerized programme for studying the water chemistry so as to select the most suitable membrane configuration and in order to provide a plant which gives a low water-rejection rate. Further help is provided to the client to make use of, often by further treatment, of the reject water. Range of R O units utilizes the most modern membrane technology and consists of a modular design.

In its simplest presentation Reverse Osmosis and Ultra Filtration system is a membrane process. That acts a molecular filters to remove (Permeable to water not salt and separating pure water and salt solution, by applying external pressure) dissolved mineral, organic, inorganic and heavy metals. It will also remove microbial matter including bacterial spores and viruses, which cannot remove by any ion exchange technique from water and wastewater.
Reverse Osmosis has emerged as a serious alternative to chemical treatment systems due to a number of reasons. The minimal use of chemicals makes it environmentally desirable. Reverse Osmosis is a simple process and the operational and maintenance costs are lower. It has higher production capacity to space ratio via-a-via other technologies. Ion exchange processes, on other hand, incur high resin replacement costs, substantially higher regeneration costs and inordinate downtime costs due the need for replacing ion exchange columns. |
While the biggest operating costs for ion exchange systems are regeneration chemicals, the major cost component in RO is energy i.e. electrical power to operate the RO feed pump.
We design the plant according to the need for tap water, brackish water & sea water application. Our production range starts from 100 LPH (Liter per hour) to 100 M3 per hour for 400 TDS to 45,000 TDS.
Two of the most cost effective ways to enjoy great tasting water in your home are with a bottled water cooler or with a home reverse osmosis (RO) system. In simple terms, reverse osmosis is the process by which water molecules are forced through a semi-permeable membrane under pressure. Reverse Osmosis systems provide filtered water everywhere, from homes and commercial applications like restaurants and hotels, to breweries and car washes, and even the space shuttle! |

Water Vatika’s RO systems typically filter water using the following steps:
- Raw tap water first flows through a sediment filter to remove dirt, rust and other solid objects.
- The water then flows into a carbon filter that takes out 98% of the chlorine and organic chemicals.
- The next stage is the reverse osmosis membrane which separates 70-99% of the dissolved contaminants from the water molecules. These removed impurities are rinsed down the drain producing the final product, “pure water”.
- This water is stored in a reservoir tank typically located underneath the kitchen sink and is accessed with a separate faucet.
- When you open the valve the water is filtered one last time with a carbon block “polishing filter” right before it reaches your glass.

Using a quality RO membrane as a strainer is typically much better than a faucet mounted filter alone. Under magnification the pores of a RO membrane are undetectable, while the pores of a pleated filter are easily seen. Reverse Osmosis treatment generally removes a more diverse list of contaminants than other systems. RO can remove nitrates, sodium, and other dissolved inorganic and organic compounds.
Water Vatika puts clean, refreshing water right in your kitchen. With a range of compact and attractive designs, our systems fit conveniently in out-of-the-way places.
