Diversity of Synthetic Dyes from Textile Industries, Discharge Impacts and Treatment Methods

Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. Lastly, we discussed the applied physical, chemical and biological strategies solely or in combination for textile dye wastewater treatments.

⚡ This is an original paraphrased summary — not copied from the abstract. Full paper available at the source link below.

• 1 The increasing demand and excessive costs of natural dye extraction engendered the discovery of synthetic dyes from petrochemical compounds.
• 2 Nowadays, they are dominating the textile market, with nearly 8 × 105 tons produced per year due to their wide range of color pigments and consistent coloration.
• 3 Textile industries consume huge amounts of water in the dyeing processes, making it hard to treat the enormous quantities of this hazardous wastewater.

These innovations can translate to real-world improvements in technology, infrastructure, and everyday tools.
