Reverse Osmosis Diaphragm Valve

Reverse osmosis (RO) is a water purification technology that uses a partially permeable membrane to remove ions, molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.

On the filtered water side, the valve application is a high-purity water application and on the effluent side, the application includes suspended solids. Both of these are ideal applications for Diaphragm vlaves.

Applications

  • High-purity water
  • Effluent Streams/control
