Process of Jar Water Plant

Pre-Treatment – Pretreatment is most important part of Reverse Osmosis System, The life of reverse Osmosis Membrane depend on Pretreatment. In a reverse osmosis contact pre-treatment refers to the various physical and chemical water treatment processes that take place upstream of the reverse osmosis plant. The typical Pre-treatment usually includes the Multi-grade Filter, Pressure Sand Filter, Granular Activated Carbon Filter and Water Softener. But Pre Treatment depends on source water quality. To design perfect Pretreatment it must require to raw water analysis.
RO System-The application of reverse osmosis to the solution of problems in water treatment requires an understanding of the basic mechanisms involved in the process, the limitations of reverse osmosis and the pre-treatment requirements. Reverse Osmosis (RO) is the process in which water is forced by pressure through a semi-permeable membrane. Water passes through the membrane while the dissolved and particulate materials are left behind. When pressure is applied to the concentrated solution, water is forced through the membrane from the concentrated side to the diluted side. The spiral membrane is constructed of one or more membrane envelopes wound around a perforated central tube. The permeate (product water) passes through the membrane into the envelope and spirals inward to the central tube for collection. Reverse Osmosis utilizes the unique properties of a semi-permeable membrane to allow fluid to pass while restricting the flow of dissolved ionic material. With pressure applied to impure water on the side of such membrane materials, pure water will pass through, leaving most of the impurities behind. The rejection of the dissolved ionic material is a function of both molecular weight and ionic charge. For example, we can expect a nominal 90% rejection of sodium chloride, which means that the product water passing through the mem
