with the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. the novel concept of photovoltaic powered ...

akin type (asymmetric) reverse osmosis membranes undergo an irreversible osmotic dehydration upon coming into contact (skin side) with salt solutions. the extent of consequent changes (in appearance; decrease in linear dimension, water flux and salt rejection) are dependent on the salt concentration. these observations are correlated with the expected morphological changes taking place during d...

Reverse osmosis is an essential technological separation process that has a large number of practical applications. The mathematical simulation significant for designing and determining the most effective modes membrane equipment operation deep understanding processes in units. This paper attempt at systematization generalizing results investigations dedicated to reverse simulation, which was p...

Semiconductor industry requires ultrapure chemicals to manufacture microelectronic devices. Hydrogen peroxide is one of the most demanded chemical by the semiconductor industry and ultrapurification processes are needed to achieve the electronic grade requirements for this chemical. Among all the ultrapurification alternatives, reverse osmosis emerges as the most desirable option according to e...

The purpose of this study was to determine the comparative environmental impacts of coupled seawater desalination and water reclamation using a novel hybrid system that consist of an osmotically driven membrane process and established membrane desalination technologies. A comparative life cycle assessment methodology was used to differentiate between a novel hybrid process consisting of forward...

Long-term reverse osmosis tests were conducted with electroplating wastes on a new membrane referred to as NS-100. This membrane consists of a polyurea layer, formed by the reaction of tolylene diisocyanate with polyethylenimine, deposited on a porous polysulfone support film. The membranes were tested as liners within 0.5411. diameter fiber glass tubes. A total of 2360 hr of continuous reverse...
