Innovative sustainable solutions for detoxifying textile industry effluents using advanced oxidation and biological...

Area of Science:

• Environmental Science
• Chemical Engineering
• Toxicology

Background:

• Textile dye wastewater presents significant environmental and health risks due to incomplete treatment.
• Conventional methods often fail to eliminate persistent toxicity and byproducts.
• There is a critical need for advanced detoxification technologies.

Purpose of the Study:

• To review and consolidate advancements in textile wastewater detoxification over the past 15 years.
• To introduce the Net Toxicity Outcome (NTO) metric for evaluating treatment efficacy.
• To propose a multi-level ecological assessment framework for sustainable wastewater management.

Main Methods:

• Critical review of Advanced Oxidation Processes (AOPs) and biological treatment integration.
• Introduction and application of the Net Toxicity Outcome (NTO) metric.
• Development of a multi-level ecological assessment framework.

Main Results:

• Integrated AOPs and biological treatments show superior detoxification compared to standalone methods.
• Standalone treatments like UV-assisted ozonation can increase toxicity.
• The NTO metric provides a standardized approach for comparing diverse treatment technologies.

Conclusions:

• Integrated bio- AOPs and biological systems offer effective solutions for textile wastewater detoxification.
• The NTO metric and ecological assessment framework are crucial for selecting optimal and sustainable treatment strategies.
• Actionable insights are provided for researchers, industry, and policymakers to improve textile wastewater management.
