Conventional and zero liquid discharge treatment plants for textile wastewater through the lens of carbon footprint analysis

Effluent treatment plants act as the last line of defense against the discharge of pollutants from industrial effluents. The higher resource consumption, variety of dyes, and auxiliary chemicals used for textile manufacturing classify it as a highly polluting industry. Standards for color, organics,...
