Dyeing and printing wastewater can only be treated through a combination of processes. While developing these processes, it’s also crucial to achieve recycling and reuse, striving for zero wastewater discharge. (1) Conditioning: For wastewater with significant variations in water quality and quantity, the conditioning tank should have a longer retention
1. Drinking water treatment generally involves purification, chlorination, and sometimes the addition of fluoridation agents. Treated water is collected by gravity or pumping into reservoirs and distributed through water towers or surface facilities. After use, the wastewater is typically discharged into the sewer system and treated at sewage treatment plants
Raw material washing wastewater: This is the largest part of food processing wastewater, usually accounting for 60%-70% of the total wastewater. When washing raw materials such as vegetables, fruits, and meat, a large amount of wastewater containing mud, sand, peels, and minced meat will be generated. This type of wastewater
