Experiment Study of Demulsifier on the Oily Wastewater Treatment

Abstract:

Adopts the method of adding demulsifiers into the oily wastewater to increase the droplets size to further improve the efficiency of oil-water separation, and puts forward the corresponding optimized indicators and methods of demulsifiers. The optimized selection of the demulsifiers and its additive dosage was carried out by indoor experiments based on the optimized indicators. Using artificial produced water to test the treatment effect of the optimized demulsifier at different action time. The experiments show that demulsifier S1 with additive dosage of 20mg/l can accordance with the requirements of the processing very well, and as the increase of action time, the average size of droplets increase and the amount of the droplets which under 1μm decrease.
