Textile Dyeing & Denim Wash

Textile dyeing operations face paramount challenges all around the world. As huge water consumers, it surely is demanding for textile plants to adapt to the new demands and requirements coming from authorities, and most importantly, from the general society, which is the more and more concerned with the industry’s environmental footprint. Thus, changing existing plants or building new ones are measures of utmost urgency when it comes to creating feasible wastewater treatment solutions for the textile dyeing industry. Care must then be taken when choosing optimal wastewater treatment solutions.

Textile companies may go from simply rejecting wastewaters into municipal sewer systems or may want to comply with the most stringent demands, such as ZLD (Zero Liquid Discharge). The latter is more and more popular among large textile producing countries. Yet, no matter the chosen alternative, new technologies always have to be introduced, as the traditional approach to treat wastewaters from the textile industry is no longer compatible with the new demands and requirements. So, new technologies, such as AOP (Advanced Oxidation Processes) – in which electrocoagulation and perozonation are included, alone or together – may be key technologies to introduce in revamping, retrofits, and even in new plants. They help the textile industry reach the challenging new rejection limits, complying with most stringent regulations, and allow for efficient and profitable wastewater reuse, adding great value to the whole process.
