An enhanced membrane bioreactor aeration ladder flat membrane fouling effect

Description: An enhanced membrane bioreactor aeration ladder flat membrane fouling effects belonging and water reuse technology in the field of environmental engineering in sewage treatment. Characterized in that the flat film is disposed on both sides of the film surface is inclined at an angle to form a trapezoidal cross section is a flat membrane, the membrane module is fixed to the ladder frame plates, placed in the bioreactor, the water under the effect of a suction pump. Trapezoidal cross section flat membrane is set to promote the occurrence of air bubbles with the inclined flat plate multiple collisions, and the tail flow swirl of bubbles in the membrane surface of greater instantaneous shear force, to improve the aeration efficiency and erosion can be effectively slowing the rate of membrane fouling, thereby enhancing the stability of the system, extend the life of the membrane, reducing the use of chemical cleaning agents, significantly reducing operating costs membrane bioreactor process, promoting widespread application of membrane bioreactor.
