Industrial Reverse Osmosis Equipment: Reverse Osmosis Design Presentation Transcript

  • 1. 1
    Industrial Reverse Osmosis: Effective Reverse Osmosis Equipment Design for Food and Beverage Applications

  • 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.

    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.

    Reverse Osmosis Equipment for Food & Beverage
    RO Array
    How the elements are grouped together
    Series
    Parallel

  • 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.

  • 9. Reverse Osmosis Equipment for Food & Beverage
    RO Pass
    An arrangement of elements where the permeate from pass 1 becomes the feed water of pass 2.
    This is done to produce a final product that is more pure than what can be achieved using only one pass.
