Filtration of water is one of the conventional techniques implemented worldwide in the 18th century to meet the basic requirements of human kind. Quality and Purity of water is major concern today as water is depleting day by day. Concept of recycle and reuse will only meet the demand when used membrane is being regenerated and reused. For the regeneration purpose, cleaning of surface is mandatory. This article experimentally discusses the cleaning reagent especially NaOH as prominent and acceptable tool for the HPA-250 membrane material to remove the adhere dye particles at different pressure [1 and 2 bar]. Permeate flux calculation provide the conclusive remark as recovery is maximum at higher pressure value [2 bar] as 47.22 % while 31.44 % is flux recovery at 1 bar pressure provided the condition of solute concentration constant.
