||The paper gives results of an evaluation of high-temperature hyperfiltration for recycle of both water and chemicals in five operating textile manufacturing processes: an atmospheric dye beck, a pressure beck, an open-width preparation range, a dye range, and a rope preparation range. Reuse of the (hot) permeate has been demonstrated in every instance. Thus, up to 9 X 10 to the 13th power Btu/yr may be conserved in the U.S. textile industry by direct recycle of the hot wastewater. Control of toxic emissions by membranes was evaluated by examining data existing in the literature: a very limited amount of textile wastewater data indicates feasibility of control of organic compounds of moleculare weights = or > 90. The potential economic payout is good, with recovery of specific chemicals and energy being paramount. A conceptual layout for closed-cycle operation of a continuous range indicates that some chemicals in the waste and a majority of the energy can be conserved by recycling.
