Experimental Study on Filtration of Oily Wastewater Based on Ultrasonic Assisted Backwashing Filter
The oily wastewater was filtered by the experiment of based on ultrasonic assisted backwash,this experiment studied the initial differential pressure of filter elment,studied the impact of differential pressure of filter ement under different backwash time by withnot ultrasonic or ultrasonic backwash,studied the impact of differential pressure of filter elemnt under different ultrasonic power,studied the impact of oil content of filtered fluid under different ultrasonic backwash flows and time,studied the regeneration ability of filter elment by ultrasonic backwash,studied the oil content of filter element by compared withnot ultrasonic and ultrasonic backwash,such as factors.This experimental results showed that well effect was obtained by ultrasonic assisted backwash in filtering oily water and polymer wastewater,under the ultrasonic backwash flows was 65 L/min,the power density was 1.7 W/cm2,the ultrasonic backwash time was 17 min,the better results was obtained by compared ultrasonic assisted backwash and withnot ultrasonic assisted backwash,the filtration efficiency of filter elment was respectively obtained,93.81%and 43.50%.
