A LOW-PRESSURE, REVERSIBLE AIRLIFT MIXING SYSTEM FOR USE WITH A MEMBRANE AERATED BIOFILM REACTOR

摘要

The invention relates to the design of an enclosure for a membrane aeration module, which incorporates a reversible, low-pressure, air-lift pump to encourage a vertical water flow through and between the membranes in the module. These enclosed membrane modules are suitable for use in membrane aerated biofilm reactors, which are used to treat water or wastewater.
