Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules and larger particles from drinking water.
Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water.
Low Pressure Reverse Osmosis Membrane that can provide RO quality water up to 2,900 gallons per day at a 15% recovery rate. It can operate at feed pressures ranging from 145 psi to 600 psi with 99.2% salt rejection. This element features the thickest feed spacer(34 mil) available in the industry today to lessen the impact of fouling. This offers the highest quality water for small and mid-size commercial systems purifying less than 10 gallon per minute(2300 L/h) of RO water and is the industry standard for reliable operation and production of the highest quality water in commercial applications.

PRODUCT NOTES:
- Proper start-up of reverse osmosis water treatment system is essential to prepare the industrial membrane elements for operating service and to prevent membrane damage due to overfeeding or hydraulic shock.
- Before initiating system start-up procedures, membrane pre-treatment, loading of the membrane elements, instrument calibration and other system checks should be completed.
- During prolonged system shutdowns, it is recommended that the membrane elements be immersed in a preservative solution. This is to prevent biological growth.
