WebMethod according to claim 8, characterized in that at low load only the second jet pump (6) designed for low load is operated. Method according to Claim 8 or 9, characterized in that during operation of only the second jet pump (6) a backflow of anode gas through the first jet pump (4) is prevented with the aid of at least one non-return valve (18). WebA nozzle increases the fluid flow velocity, while a diffuser decreases the velocity. Nozzles are essential for controlling the exit velocity of a fluid flow, while diffusers improve distribution and residence time in wastewater treatment plants. Nozzles are for speeding up fluids to create high velocities with low-pressure drops.

WebThe principle of diffuse ceiling ventilation is to supply fresh air to the occupied zone from perforations or slots in the suspended ceiling panels, see Figure 1 [1]. Due to the large opening area of the supply inlet, the air enters the occupied zone with very low velocity and no fixed direction, therefore given the name of ‘diffuse’. http://www.diva-portal.org/smash/get/diva2:8911/FULLTEXT01.pdf ra2302
