A new mathematical model was developed to predict the cylindrical effect of membrane performance in pressure retarded osmosis process. The transport layers (the draw side boundary and porous membrane) were divided into very thin sublayers with constant mass parameters, among others a radius every sublayer. obtained second-order differential balance equations solved analytically, parameters writ...

Electrical double layer expansion (CDLE) has been proposed as a promising alternative to reverse electrodialysis (RED) and pressure retarded osmosis (PRO) processes for extracting osmotic power generated by the salinity difference between freshwater and seawater. The performance of the CDLE process is sensitive to the configuration of porous electrodes and operation parameters for ion extractio...

Polyethylene terephthalate mesh (PET) enhanced cellulose acetate membranes were fabricated via a phase inversion process. The membrane fabrication parameters that may affect the membrane performance were systematically evaluated including the concentration and temperature of the casting polymer solution and the temperature and time of the evaporation, coagulation and annealing processes. The wa...

Pressure-retarded osmosis (PRO) is a promising membrane technology for harnessing the osmotic energy of saline solutions. PRO typically considered with seawater/river water pairings however greater can be recovered from hypersaline solutions including produced (PW) petroleum industry. One major challenges facing utilization PW its high fouling propensity on membranes. In this unique experimenta...

corn steep water as effluent which arrives in environment from starch processing industry has adverse effects on the environment and also large volume of fresh water is wasted. corn step water is composed of high concentration of proteins, sugar, starch, vitamin and minerals, so it can be used as substrate for production of biological products. hence, corn steep water concentration is important...

Investment in clean energy is demand this century due to abundance of CO2 accumulation the world cause several environmental issues. Therefore, harvesting may assist reducing carbon footprint create a green environment for sustainable living. The salinity gradient one energies with concept mixing both salt concentration water from ocean and fresh river an osmotic pressure power-up generator pro...
