english 1. Papermaking industry
Papermaking wastewater contains a large amount of suspended pollutants such as fine fibers, fillers, lignin, etc. DAF flotation equipment can effectively remove these suspended matter, purify the wastewater, realize the recycling of water resources, reduce pollution to the environment, and recover useful substances such as fibers to reduce production costs.
2. Food processing industry
Wastewater generated during food processing usually contains organic matter such as oil, protein, and starch. DAF flotation equipment can generate tiny bubbles by introducing air into the wastewater, so that these organic matter attach to the bubbles and rise to the water surface with the bubbles, thereby achieving solid-liquid separation and purifying the wastewater.
3. Petrochemical industry
Petrochemical wastewater has complex components and contains a variety of pollutants such as oils, phenols, and aromatics. DAF flotation equipment can first separate the floating oil and part of the dispersed oil in the wastewater through flotation, reduce the burden of subsequent treatment processes, and improve the efficiency and stability of the entire sewage treatment system.
4. Printing and dyeing industry
Dyeing and printing wastewater has the characteristics of high chroma, high organic content, and strong alkalinity. DAF flotation equipment can make dyes and other colored substances form flocs after adding appropriate flocculants and coagulants, and remove them through flotation separation, thereby reducing the chroma and organic content of wastewater and creating conditions for subsequent deep treatment.
5. Pharmaceutical industry
Pharmaceutical wastewater contains a variety of organic pollutants and microorganisms. DAF flotation equipment can remove suspended solids and some organic matter in wastewater through flotation, improve the water quality of wastewater, provide good water inlet conditions for subsequent biological treatment or other deep treatment processes, and ensure that wastewater meets discharge standards.
