Economic study for blend membrane production

Abstract Background In this work, an economic study for production reverse osmosis (RO) membrane from a blend of polyvinylchloride (PVC) with cellulose acetate (CA) was investigated. The model predicting RO performance developed based on laboratory experimental data. conducted to investigate the feasibility producing polyvinylchloride/cellulose (PVC/CA) using large-scale batch casting machine and fabricated in workshop National Research Centre, Egypt. Results cost prepared technique reached 36 $/m 2 flat sheet polymeric which cheaper than sheets commercial membranes. original capital investment will be recovered 7.5 years estimation lifetime 25 years. Conclusions revealed that establishing small factories produce membranes is promising create reasonable profit.
