The review also touches upon advanced oxidation processes (AOPs) and technology integration:
: Bio-aerogel particles and engineered biochar.
: Efficiency is heavily dictated by the pH of the solution , initial dye concentration, temperature, and adsorbent dosage. For instance, a lower pH (around 6) was found optimal for certain bagasse-based treatments. Emerging Technologies Mentioned
: Synthetic dyes are often carcinogenic, mutagenic, and toxic . Traditional treatment methods, like using commercial activated carbon, are often too expensive for large-scale industrial use. Key Findings & Methods Evaluated
: Fly ash, coal, and malt bagasse (the latter showing up to 94% removal efficiency for methylene blue).
The textile industry is a major global economic driver, but its production stages—specifically —create significant environmental hazards due to the discharge of large volumes of colored wastewater. This review evaluates modern methods to mitigate these issues.
Below is a detailed review of the core themes, findings, and technical insights from this specific work.
: The study explores adsorption , ion exchange, irradiation, coagulation, and membrane-based filtration.
