2. 2 Food and Beverage Reverse Osmosis Equipment Typical Food and Beverage Reverse Osmosis applications: Can and bottle wash water Sterilizers/pasteurizers Concentration of food or beverage liquids Integral in the treatment of domestic water to produce bottled water The end use of the RO will dictate its design. In some applications the permeate is the desired component and in others the reject is the desired component. www.LayneWater.com
3. 3 Industrial Reverse Osmosis Definitions Osmosis Pure water diffuses from the dilute side to the concentrated side of a semipermeable membrane. Reverse Osmosis High pressure is applied to the concentrated side of the membrane and pure water flows to the dilute side. Net Driving Pressure The pressure applied to the membrane to create the reverse osmosis. Typically 200 – 450 psi. www.LayneWater.com

5. 5 Reverse Osmosis for Food and Beverage RO Element types Spiral wound Hollow fiber Large tube Flat plate www.LayneWater.com
6. 6 Reverse Osmosis Equipment for Food & Beverage RO Array How the elements are grouped together Series Parallel www.LayneWater.com
7. 7 Reverse Osmosis for Food and Beverage RO Stage A series of elements linked together such that the reject (concentrated) water from stage 1 becomes the feed water for stage 2. This is done to reduce wastewater and to increase the total recovery from the RO array. www.LayneWater.com
