Synergy of textile dyeing wastewater treatment along with water reclamation using membrane-enabled approach

The textile industry is being the major consumer of water, salts, dyes, and toxic chemicals and generates effluents during various unit operations containing significant quantities of unutilized resources. The discharged untreated effluent leads to deleterious environmental effects as well as contaminate the natural freshwater reservoirs. A novel treatment technology needs to be developed with a high potential of handling the complex textile dyeing effluent as well as high capability of quality water reclaimable potential. The new emerging membrane-based sustainable technology can be cost-effective as well as eco-friendly remediation alternatives for textile wastewater treatment, along with superior treated water quality reclamation especially under some scenarios where bioremediation often fails. The membrane-integrated hybrid treatment systems (such as membrane bioreactor, electrodialysis, membrane distillation, and forward osmosis) have the potential to achieving minimal/zero liquid discharge during the treatment of textile dyeing effluent. The present book chapter thus elucidates the contribution of membrane-based treatment technologies for resource recovery (water) while treatment of textile wastewater.
