Treatment Process of Demlsifier for Polishing Wastewater

Treatment Process of Demlsifier for Polishing Wastewater

Polishing wastewater emulsion breaking agent is a kind of chemical agent specially used to treat emulsified oil and suspended matter in polishing wastewater. Its main function is to realize the separation of oil and water by destroying the stability of emulsion, so as to reduce the concentration of pollutants in wastewater and facilitate the subsequent treatment.

Characteristics of polishing wastewater demulsifier

Efficient removal of pollutants: can remove 95% of COD in wastewater, significantly reduce the pollution load of wastewater.

Low dosage and cost: the dosage of emulsion breaker is less, but the treatment effect is significant, which can save more than 65% of the treatment cost.

Easy to operate: only a small amount of agents to achieve rapid defactomy and flocculation precipitation, simple operation, high efficiency.

Environmental friendly: demulsifier is environmentally friendly and will not introduce secondary pollution.

Usage method

Adjust the pH value: adjust the pH value of polishing wastewater to about 7-8 to facilitate the role of demulsifier.

Add the emulsion: add the emulsion to the wastewater and stir evenly to make it fully contact with the emulsified oil and suspended matter in the wastewater.

Flocculation and precipitation: add an appropriate amount of polyacrylamide (PAM) and other flocculants to accelerate the flocculation and precipitation of suspended matter.

Solid-liquid separation: through the sedimentation tank or filter press and other equipment, the separated oil and suspended matter will be removed, to achieve the purification of wastewater.

Application advantages

Rapid weaning: can quickly destroy the stability of emulsified oil, to achieve oil and water separation.

Strong adaptability: suitable for a variety of complex wastewater components, including wastewater containing heavy metal ions, oils and surfactants.

Does not affect subsequent treatment: the wastewater after lactation can be directly entered into biochemical treatment or other advanced treatment processes.

Matters need attention

Wastewater composition analysis: the specific composition of wastewater should be analyzed before use to select appropriate demulsion agent.

Optimization of dosage: according to the emulsification degree of wastewater and the concentration of pollutants, determine the best dosage of emulsion breaking agent.

Environmental condition control: the performance of demulsifier may be affected by environmental conditions such as temperature and pH value, so ensure that it is used under appropriate conditions.

Through the rational use of emulsions, it can effectively solve the emulsification problem in polishing wastewater, improve the efficiency of waste water treatment, and reduce the treatment cost.
