Toluene diamine (TDA) is a main carcinogenic aromatic pollutant in some industrial wastewater. In this study, the reverse osmosis with DSS-HR98PP as the membrane was employed for the removal of TDA in an aqueous environment. The Box–Behnken Design (BBD) of the experimentwas used to consider the effect of operational variables such as pressure, pH and the feed volu...
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...
