Demulsifier is a necessary product for oil, emulsion and other wastewater, and is a water pollution treatment agent developed to treat emulsion oily wastewater. With the improvement and diversification of product requirements in all walks of life, the added material is also complicated, which leads to the sewage is also more difficult to treat, and the general water treatment agent for oily wastewater can not be met. Therefore, the use of demulsifier in these industries is very common, and sewage treatment personnel have been very skilled in the use of demulsifier to treat such wastewater.
The effect of using demulsifier in sewage treatment: by adding demulsifier, the oil and colloidal particles in the wastewater can be quickly separated, so that they lose their repulsive force and attraction. When the stability of the wastewater changes, the oil droplets in the emulsion flocculate into alum flowers and quickly form floc, which can show the effect of oil-water separation and clear supernatant. Demulsifier can quickly reduce the excessive substances such as organic SS, chrominance ammonia nitrogen and heavy metals in the wastewater by flocculation precipitation, and the wastewater treated by the agent can show clear and transparent fruit at the same time, improve the BOD5/COD value of the wastewater, enhance the biodegradability of the wastewater, and provide favorable conditions for the subsequent biochemical system, thereby reducing the pressure of enterprises.
Use demulsifier in just 3 steps:
Demulsifier →PH regulator → Polyacrylamide (PAM)(Note: The use of demulsifier can replace the use of polymerized aluminum gasification (PAC)). Demulsifier can be used in sewage treatment in a variety of industries, such as: oilfield industry, hardware cleaning and processing industry, food processing industry, electrophoresis wastewater, chemical wastewater, mechanical urban sewage and other industries have a good effect.
