Wastewater treatment plant PURE - MBR®

Field of Application The continuous-flow systems as conventional wastewater treatment technologies are widely known. The membrane bioreactor version of this, called the PURE-M®, is coupled with a highly efficient phase separation. The advantage of the membrane separation is that there is no need for the construction of a secondary-clarifier unit. Moreover excellent effluent quality parameters are ensured. Advantages and parameters: continuous flow continuous treated water discharge small space requirements due to its load capacity Purified water concentration of suspended solids negligible There is no need to construct secondary clarifier The system can be expanded further, outer membranes can be built in if necessary The membranes are outfitted with cleaning systems Description of the technology The dissolved organic materials in the wastewater are transformed by the microorganisms into carbon dioxide, water and biomass under suitable nutrient and oxygen supply. After the nitrification and denitrification - which can take place in the same pool or in separate spaces - the purified waste water is removed from the system through the membranes. Regarding the placement of membranes there are two options; they are placed in separate basins or in the biological basin. Continuous or intermittent aeration is required for this technology via fine bubble deep aeration units. The quantity of the input oxygen can be controlled via measurements by an oxygen probe; aeration is programmable for denitrification and for lowest energy consumption.
