CONDUCTIVITYUsed as an approximate measurement of mineral content. Units commonly used as micromhos/cm.ELEMENTOften times referred to as membrane. Can be used interchangeably. This refers to thefiltration material that fits inside the pressure vessel.FLUXPermeate flow through a membrane. Generally calculated as liters/m 2 /hour (lmh).FOULINGRefers to the flux decline of an element.INTERCONNECTORThis device connects two spiral elements together or an element to the permeate end cap.MEMBRANETerm used to refer to the semi-permeable material by which the separation process takesplace.MEMBRANE CUTOFFTerm used to describe the molecular weight size, which becomes too large to passthrough a specific membrane. The molecules, which are larger than the cutoff willbe retained or rejected whereas the smaller ones will pass through (permeate).MODULEA device which contains the elements, such as a ceramic module or plate and framemodule.PERMEATEThe material which passes through the membrane.22
PERMEATE END CAPThis device is generally located on the downstream end, but not always, of the vessel andthe permeate exits through it.PERMEATE TUBEA tube at the center of a spiral wound element of which the permeate flows into and thusexists the element. The interconnector also connects into this. Sometimes referredto as the center tube.RECIRCULATING PUMPSometimes called a booster pump. In a recirculation loop the pump is necessary forcreating an optimum cross flow across the membrane surface.RECOVERYGenerally described as a percentage. Used with reverse osmosis systems. Calculated as the permeate flREJECTIONGenerally described as a percentage of salt rejection in a reverse osmosis membrane.Calculated as the percentage of salt which is held back by the membrane. R=1-(C p /C b ), whereR = RejectionC p = concentration in permeateC b = concentration in retentateRETENTATEOften times called the concentrate. This material is held back by the membrane and isthus concentrated.VESSELOften times called the pressure vessel. This tube contains the spiral element inside it.23
