Paper Mill Circulating Water Demulsifier
In China, the amount of industrial wastewater discharged by the paper industry accounts for 1 / 6 of the total amount of industrial wastewater, and the amount of the wastewater is large and the pollution range is wide, so it is urgent to treat the wastewater. The following is about the specific role and advantages of demulsifier in the treatment of paper wastewater:
1. Processing function
Demulsifier can specifically separate emulsified oil and colloidal flocculation in precipitated water. Papermaking wastewater often contains a large amount of emulsified oil and colloidal substances, which not only make it difficult to treat the wastewater, but also affect the environment. Emultacast can destroy the stability of these substances and separate them from the water, thus realizing the effective purification of wastewater.
Demulsifier also has the function of deep treatment. In the process of papermaking wastewater treatment, multi-stage treatment is often needed to meet the standard. Demulsifier can play an important role in the deep treatment stage, further remove the trace amount of suspended matter in wastewater, and improve the treatment effect of wastewater.
2. Advantages
A.the addition amount is small, the removal of oils, colloids, surfactants fast.
B. the cutting fluid, film washing agent, high concentration of cleaning waste liquid, can be treated to the wastewater clear recycling standards.
C.Emulsion breaker can greatly reduce COD, color degree, heavy metal, total phosphorus and other effects.
3. Attentions
The selection and use of demulsifier needs to be adjusted and optimized according to the actual situation of papermaking wastewater. Different papermaking processes and wastewater components may lead to differences in the treatment effect of emulsions.
When using the emulsion breaker, it is necessary to follow the relevant standard operating procedures to ensure the safety of the operators and the stability of the environment.
