Bioréacteur à membrane
MBR

Le terme « bioréacteur à membrane » (MBR) est généralement utilisé pour définir les processus de traitement des eaux usées dans lesquels une membrane sélective permanente, par ex. la microfiltration ou l'ultrafiltration est intégrée à un processus biologique - un bioréacteur de croissance en suspension.

APG-Neuros - Pioneer manufacturers in MBR facilities

APG-Neuros one of the first manufacturers to provide high speed turbo blowers in MBR wastewater treatment facilities, working with MBR manufacturers such as GE, Evoqua (formally Siemens) and KOCH, currently APG-Neuros has more than 110 units in operation in MBR application.

Treatment Process

MBRs differ from ‘polishing’ processes where the membrane is employed as a discrete tertiary treatment step with no return of the active biomass to the biological process. All commercial MBR processes available today use the membrane as a filter, rejecting the solid materials which are developed by the biological process, resulting in a clarified and disinfected product effluent.
A membrane bio reactor is essentially a version of the conventional activated sludge (CAS) system. While the CAS process uses a secondary clarifier or settlement tank for solid/liquid separation, an MBR uses a membrane for this function. This provides a number of advantages relating to process control and product water quality.
