Info

Defoamer IntoleranceUse of anti-foaming agents is not recommended since they can cause irreversible loss offlux.* If use of anti-foaming is necessary, please consult a Niro representative.No chemical that has not been approved by Niro should be used for membrane cleaningor shall come in contact with the membranes.∗ A common component of anti-foaming agents in silicon, which is the primary causeof the flux loss. Silicon is also found in many lubricants, which also should not comein contact with the membranes.20
DEFINITIONSBefore the discussion goes too far, it would be helpful to define a few terms, which areoften times used in the membrane filtration field. By no means do we wish toinclude all related terms, but just a few which are pertinent to the discussion and tothe successful operation of the NIRO system.A.T.D. (Anti-telescoping device)The device is located on the downstream end of the spiral element to prevent the leavesfrom telescoping or being pushed downstream. Often times the A.T.D. andinterconnector are built as one.B.O.D. (Biological Oxygen Demand)Generally expressed as BOD 5, this is the quantity of oxygen required to decomposeorganic material, expressed as parts per million (PPM).BACK PRESSUREThe system operating pressure which is measured at the concentrate end of the element.BACK PRESSURE VALVEThe valve which the concentrate is throttled through. Often times referred to as theconcentrate flow control valve.BOOSTER PUMPSee recirculation pump.CENTER TUBESee permeate tube.CIPClean in place: A method for cleaning the system without disassembly.CONCENTRATESee retentate.21
