RO Purification System

RO Purification System RO purification system for purifying water to get drinking water. The main technical flow is : Raw water tank--- Raw water pumpQuartz sand filter--- Active carbon filter--- RO module--- Product water tank Introduction of pretreatment and RO module Pre-treatment is important when working with ROmembranes due to the nature of their spiral wound design. The material is engineered in such a fashion to allow only one way flow through the system. As such the spiral wound design doesn't allow for backpulsing with water or air agitation to scour its surface and remove solids. Since accumulated material cannot be removed from the membrane surface systems they are highly susceptible to fouling (loss of production capacity). Therefore, pretreatment is a necessity for any RO system. The RO membrane assembly consists of a pressure vessel with a membrane that allows feedwater to be pressed against it. The membrane must be strong enough to withstand whatever pressure is applied against it. RO membranes are made in a variety of configurations, with the two most common configurations being spiral-wound and a hollow-fiber. Reverse osmosis is a process that is often used for water. It works by using pressure to force a through a , retaining the on one side and allowing the pure to pass to the other side. This is the reverse of the normal process, which is the natural movement of from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied.
