During the operation of water-based ink printing plants, wastewater containing water-based ink is generated, which needs to be treated appropriately to meet discharge standards. The following are sewage treatment equipment that water-based ink printing factories may need to equip:

Printing plants using water-based ink do indeed require wastewater treatment. This is because water-based ink wastewater has some special properties, such as high COD (chemical oxygen demand), high chromaticity, and difficult biodegradation. If directly discharged into the environment, it will cause serious pollution to water bodies, threatening human production and life as well as the ecological balance of nature.
