Reverse Osmosis

dfghde
Reverse Osmosis removes up to 99% of total dissolved solids. OSMOTECH RO membranes deliver hygienic drinking water by reducing concentration of Arsenic, Barium, Cadmium, Chromium, Chromium (Trivalent), Copper, Cysts, Turbidity, Fluoride, Lead, Radium 226/228, Selenium, and TDS.
RO involves sorting out water from a solution of dissolved solids by forcing water through a semi- permeable membranes. As pressure is applied to the solution, usually by a pump, water and other molecules with low molecular weights (less than about 200 grams per mole) pass through micro pores in the membranes. Larger molecules are hold by the membranes. 
Most RO technology uses a cross flow process to allow the membranes to continually clean itself. As some of the fluid passes through the membranes the rest continues downstream, sweeping the rejected species away from the membranes.

Reverse Osmosis Process

Applications of RO

  • Boiler Feed Water Treatment: RO is used to reduce the solids content of waters prior to feeding into boilers for the power generation and other industries.
  • Pharmaceutical: Reverse osmosis is an approved treatment process for the production of grade water for pharmaceutical applications.
  • Food & Beverage: Water used to process food products and to produce beverages is often treated by a reverse osmosis system.
  • Metal Finishing: RO systems have been successfully applied to a variety of metal finishing operations including several types of copper, nickel and zinc electroplating; nickel acetate seal; and black dye.
