• Modifications of support layer were conducted using a commercial PTFE/PP bi-composite membrane. • Macro punctures of support layer were designed based on the porosity of the support layer. • Porosity of support layer and sizes of macro punctures affected the fluxes of the modified membranes. • The or

Direct contact membrane distillation (DCMD) module was operated with three flat sheet commercial membranes (PTFE/PP 1.0, PTFE/PP 0.45, and PTFE/PE 0.45) under various operating conditions. High flux was observed when the PTFE/PP 1.0 membrane was used and there was no membrane wetting when the feed con

Biofouling due to microbial growth on the RO membrane adds significant osmotic pressure and causes frequent chemical cleaning which reduces the life of RO membrane. Biocides such as chlorine, ozone, and UV have been used to control microbial growth correlated to the biological fouling of the RO memb

Concentrate staging which is one of the configurations of reverse osmosis membrane system has made hybridization of different types of membranes such as sea and brackish water reserve osmosis membranes possible. And the essence of hybridization of membranes is to equilibrate permeate and lower energ
