Abstract
A membrane bioreactor includes a tank, a porous pre-filtering element mounted in the tank for conducting a primary filtration of wastewater, at least one membrane module mounted in the tank and disposed downstream of the porous pre-filtering element for conducting a secondary filtration of the wastewater, and a turbulent flow-forming unit. The membrane module cooperates with the porous pre-filtering element or another membrane module to define a compartment therebetween for receiving the wastewater pretreated by the porous pre-filtering element. The turbulent flow-forming unit is associated with the compartment for generating turbulent flow in the compartment.

A membrane bioreactor, comprising:
- a tank adapted to receive wastewater therein;
- a porous pre-filtering element mounted in said tank for conducting a primary filtration of the wastewater;
- a membrane module mounted in said tank and disposed downstream of said porous pre-filtering element for conducting a secondary filtration of the wastewater pretreated by said porous pre-filtering element, said membrane module cooperating with said porous pre-filtering element to define a compartment therebetween for receiving the wastewater pretreated by said porous pre-filtering element;
- and
- a turbulent flow-forming unit associated with said compartment for generating turbulent flow in said compartment.
A membrane bioreactor comprising:
