Industrial Reverse Osmosis Equipment: Reverse Osmosis Design

  1. 1. 1<br />Industrial Reverse Osmosis: Effective Reverse Osmosis Equipment Design for Food and Beverage Applications<br />www.LayneWater.com<br />1<br />
  2. 2. 2<br />Food and Beverage Reverse Osmosis Equipment<br />Typical Food and Beverage Reverse Osmosis applications: <br />Can and bottle wash water<br />Sterilizers/pasteurizers <br />Concentration of food or beverage liquids <br />Integral in the treatment of domestic water to produce bottled water<br />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.<br />www.LayneWater.com<br />
  3. 3. 3<br />Industrial Reverse Osmosis Definitions<br />Osmosis<br />Pure water diffuses from the dilute side to the concentrated side of a semipermeable membrane.<br />Reverse Osmosis<br />High pressure is applied to the concentrated side of the membrane and pure water flows to the dilute side. <br />Net Driving Pressure<br />The pressure applied to the membrane to create the reverse osmosis. Typically 200 – 450 psi.<br />www.LayneWater.com<br />
  4. 4. Reverse Osmosis Design for Food and Beverage<br />Four main components to an RO system<br />Element<br />Array<br />Stage <br />Pass<br />4<br />www.LayneWater.com<br />
  5. 5. 5<br />Reverse Osmosis for Food and Beverage<br />RO Element types<br />Spiral wound<br />Hollow fiber<br />Large tube<br />Flat plate<br />www.LayneWater.com<br />
  6. 6. 6<br />Reverse Osmosis Equipment for Food & Beverage<br />RO Array<br />How the elements are grouped together<br />Series<br />Parallel<br />www.LayneWater.com<br />
  7. 7. 7<br />Reverse Osmosis for Food and Beverage<br />RO Stage<br />A series of elements linked together such that the reject (concentrated) water from stage 1 becomes the feed water for stage 2.<br />This is done to reduce wastewater and to increase the total recovery from the RO array.<br />www.LayneWater.com<br />
  8. 8. A Two Stage RO System for Food and Beverage<br />www.LayneWater.com<br />
  9. 9. Reverse Osmosis Equipment for Food & Beverage<br />RO Pass<br />An arrangement of elements where the permeate from pass 1 becomes the feed water of pass 2.<br />This is done to produce a final product that is more pure than what can be achieved using only one pass.<br />9<br />www.LayneWater.com<br />
