Application: Retrofitting An Existing MBR Plant

Membrane bioreactors (MBRs) with submerged membrane modules are an attractive choice for the next generation of wastewater treatment plants. The technology offers improved effluent quality and a substantially smaller footprint compared to the combination of a conventional wastewater treatment plant followed by filtration or ultrafiltration (UF).

Many MBR owners have become concerned with the membrane's proprietary nature, which is critically important to the MBR process. The membrane filtration modules used in MBR applications are typically designed with either hollow fibers or flat sheet panels and may not be compatible with other brands. Furthermore, electromechanical equipment supporting the membrane operation can take many forms and modes of operation, exacerbating compatibility issues between different membrane manufacturers.
