MBBR and activated sludge mixing techniques can improve the process ability more than 50% and achieve the goal of denitrification and phosphorus removal. Under the condition of without any increase in tank capacity, combine with A2/O, oxidation ditch, SBR and etc process.
Apply to the high concentration organic wastewater treatment, greatly improves performance of the sedimentation of activated sludge and effluent water quality, has the high ability to resist impact load, at the same time to avoid the problem of the sludge bulking, makes running more stable and reliable.
Can deep treatment the waste water, strengthen nitrification and denitrification effect; Improve the removal rate of organic matter and ammonia nitrogen, ensure the effluent water quality
MBBR-SBR combination process, the best from two well-known technologies: activated sludge and MBBR, are combined. This process provides extra advantages that can be described by the unbelievable formula: 1+1=3!
MBBR process is a compact solution requiring little process volume to achieve both reduction of organic material and nitrogen. This process solution is often a cost effective way of upgrading an existing activated sludge system to also comprise nitrogen removal or improve the capacity of the nitrogen removal process.
Thanks to the biofilm solution, the long suspended sludge age normally needed in the AS to achieve nitrification can be reduced. A reduction of the sludge concentration in the AS will also lead to less sludge load on the secondary clarifiers.
Another benefit is that a short sludge age will often reduce the risk of growth of filamentous bacteria and generally, the biological activity is higher in an AS process with low sludge age than in one with a high sludge age. One can therefore achieve high denitrification activity in MBBR combination process.
MBBR combination process can be used both in plants designed for only nitrification or for nitrogen removal with denitrification normally taking place in a denitrification reactor without carriers. It can also be used together with an anaerobic selector for biological phosphorus removal.
Factors that affect the overall design of an upgrade include media type, aeration system, dissolved oxygen concentration, effluent NH3-N concentration, basin configuration and hydraulic profiles through the basin. All these elements are necessary design factors, which have to be considered to create a well working system. Should one of these factors not be considered or designed properly, the overall treatment system could be adversely affected
