Abstract: A mobile device for biological treatment of bioreactor-type wastewater with a submerged membrane enabling treatment of greywater and blackwater has an inlet duct for effluent to be treated and an outlet duct for treated and filtered water connected to a permeate pump. The device includes a container, the interior volume of which has a parallelepiped appearance with two large vertical lateral sides, and a membrane filter having an assembly of parallel, planar filtration membranes also with a vertical appearance. The membranes are connected to a downstream collector collecting the filtered water and connected to the outlet duct. The permeate pump ensures a transmembrane flow less than the subcritical flow. At least one diffuser of fine air bubbles is located at the base of each column. Each diffuser is connected to a regulating solenoid valve and to pump, ensuring therein an airflow greater than or equal to 10 Nm3/h per diffuser.
