Annotation

To intensify the process of membrane separation of oil emulsions, the membrane element is sub jected to constant exposure to ultrasonic vibrations with a frequency of 35 kHz. In the separation of oil emul sions, a decrease in the productivity of the membranes from 22 to 40 times is found, due to the accumulation of oil particles in the near-membrane layer. As a result of the action of ultrasound on the membranes, an increase in specific productivity of up to 30% for microfiltration membranes and up to 45% for ultrafiltration membranes is observed. The impact of ultrasound prevents the aggregation of oil particles and the formation of a gel layer. After separation of the oil emulsion by polymeric membranes, the concentration of oil products decreases. The retention capacity of microfiltration membranes for oil products ranges from 79 to 88% and the retention capacity of ultrafiltration membranes from 91 to 99%. Under the influence of ultrasound, fric tion forces arise between the particles of oil and the dispersion medium, which leads to a decrease in the par ticle size, which increases the likelihood of particles slipping through the pores of the membrane. The decrease in the retention capacity for microfiltration membranes averages 3% and for ultrafiltration mem branes by 0.6%.
