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

Abstract: 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 reutilization in a subsequent dying process, along with the reclaimed water. The HFFO2 membrane was efficiently cleaned by a backwash process, restoring the initial water flux. These results indicate the suitability of forward osmosis to reuse dyes and water from textile wastewater, reducing the environmental impact of this industry and favoring its sustainability.
