The permeate quality obtained at 12 bar satisfied the actual process water quality except for COD parameter. However,COD value
of permeate was below 25mg/L which is suitable for process water
and also permeate had excellent quality in terms of other parameters at 28 bar. As aconclusion,it was observed that there sulting
permeate was colorless,free from Suspended solids and total hardness at this transmembrane pressure. In addition,COD,chloride,
sulphate and conductivity removal were obtainedas>97%,82%,
>99% and87%,respectively.
