This project is developed as an upgrade of an existing sewage waste water treatment system at the Palm Jumeira. An existing facility capable of treating 3500 m3/day municipal sewage has to be increased in water treatment capacity to reach17.000 m3/day. Both footprint and current construction are too limited to be able to house this capacity as normal sewage treatment, where a solution is offered to separate the sludge from the treated wastewater by Membrane BioReactor (MBR).

The total scope of this project exists of 20 skids with a dedicated feed pump and 26 membrane elements each.

The technique used to change this plant is called the AirLift MBR Technology of Norit. The technique is particular useful in the case of upgrading existing plants, as the membrane secion responsible for separating the clean water from the sludge is put outside the reactor. As such there are no major changes necessary to the existing site. As a “dry” solution (not being submerged in the reactor), maintenance and cleanability are simply, safe and allow full automation. The Airlift MBR process wil consist of an activated sludge extended aeration biological treatment process combines with an ultrafiltration membrane system for the separation of activated sludge from treated effluent. The UF membrane system is 100% efficient at separating sludge from the mixed liquor suspended solids (MLSS).
