Water-based ink wastewater treatment remains part of the water pollutants from the textile dyeing and finishing industry. As a new and typical type of dyeing and printing wastewater within the dyeing and finishing industry, its prominent characteristics are high CODcr, high color intensity, and poor biodegradability.
1) Water-based inks are mainly used in low-end printed materials such as books and magazines, corrugated paper printing industries with low requirements, flexographic printing fields such as product packaging in tobacco factories, wineries, pharmaceutical factories, cosmetics companies, children’s toy companies, and composite paper packaging for milk and beverages, as well as other cardboard packaging industries.
2) During the production and application of water-based inks, a certain amount of water-based ink wastewater is generated due to equipment cleaning.
3) The main source of wastewater from water-based inks in application areas is ink replacement.
