Pentair X-Flow Airlift Solution delivers a cost-effective membrane bioreactor (MBR) solution for municipal and industrial wastewater treatment applications. Synergize the crossflow filtration principle at low velocities enhanced with the Airlift process to create sufficient turbulence to solve cake layer build-up and operate at high flux rates. The X-Flow Airlift solution eliminates the build-up of debris at the membrane inlet with the drain step.

Airlift uniquely combines membranes with biological treatment. With carefully selected partners for the biological part, Pentair develops innovative and ready-to-use membrane installations that meet both regulatory and financial KPI’s. 

The need for reusing wastewater, both industrial and municipal, requires top quality membranes which provide directly reuseable water. The ultrafiltration membranes applied can be compared to those used in drinking water plants. Energy consumption is at the level of submerged membrane systems or lower, due to the efficient use of process conditions for flux enhancement. 

Another major advantage of the Airlift technology is that the membrane modules are placed outside the bioreactor in a clean and dry setup. The wastewater itself is inside the membranes rather than outside, thus eliminating the problem of maintaining modules submerged in activated sludge. The membranes are easily accessible and cleaned.
