Treatment of industrial textile wastewater by means of forward osmosis aiming to recover dyes and clean water.

ABSTRACT: The textile industry is one of the largest water consumers, and, as a result of its activity, it generates tons of wastewater. In this research, forward osmosis has been employed to tackle the critical need of treating textile wastewater. The HFFO2 membrane (Aquaporin) was used to process large volumes of real cotton dyeing wastewater, wool dyeing wastewater, and several types of textile end-of-pipe wastewater. In all cases, the permeate flux was between 6 and 8 L·h^{- 1} m^{- 2} during the major part of the process. The recovery of clean water from each wastewater surpassed 90 %, whereas the membrane rejected more than 87 % of total dissolved solids. As a result, textile dyes were concentrated on the feed side of the membrane, which enables their recovery and potential reu
