The MBBR Bio Media has been extensively tested and implemented into numerous wastewater plants worldwide for decades. The AMB Bio
Media has proven to be superior to any known MBBR bio media, and can handle pH variation, shock loading, cold temperature, and drastically reduce plant size. The AMB Bio Media has a proven record of stabilizing most plants with wastewater upgrade MBBR technology.

Moving Bed Biofilm Reactor (MBBR) processes improve reliability, simplify operation, and require less space than traditional wastewater treatment systems.
Okay. This one is on the engineers. The idea of a fixed-film process is that the biofilm stays in the tank. This is what sets the MBBR biological process apart from traditional activated sludge processes. On occasion, there have been reports of the carrier media getting out of the reactor. Inside an MBBR biofilm reactor, there is supposed to be a sieve screen mounted to the outlet that prevents this from happening. But, if the sieve is not sized correctly (or installed correctly in some cases), the media can slip through. This problem can be avoided entirely if you partner with a good company with competent designers that make sure to double check things like making sure the mesh openings in the sieve aren't bigger than the carriers.
This is an advanced biological reactor for aquaculture and aquarium wastewater treatment. MAT Moving Bed Biofilm Reactor (MBBR). Moving Bed technology presents several operational advantages, compared to other conventional LSS biological treatments. Smaller biological reactor volumes and smaller secondary settling surface are needed in order for bacteria slime to settle and nourish.
For denitrification, anoxic Moving Bed Biofilm Reactor MBBR tanks are used. The anoxic tank is similar to aerobic Moving Bed Biofilm Reactor MBBR tank described above except that no oxygen is supplied. The tank contains no diffusers and the media is kept in suspension in the reactor through submersible mixers. Other feature such as the screen is the same as aerobic reactor although the design may be slightly different.

MBBR Technology
The media on which the biofilm develops are carefully designed with high internal surface area having density slightly less than the water so that it can easily float. The most commonly used solid surface for attached growth processes are; stones, clinker, sand, activated charcoal, ceramic, metals, plastic sheets, and foams. There are different types of media which can be used as a media for the microbial growth. Specific surface area (SSA) is the main factors that contribute the biomass characteristic in water treatment and as well as the total performance of IFAS and MBBR system. Table shows the types of carriers available in the markets and being apply in laboratory and pilot plant study for both MBBR and IFAS system. In MBBR and IFAS system, aeration is used to provide DO for the biomass and also to create the cross flow velocity to scour the biomedia surface . The high crossflow activities that are generated at the biomedia surface tend to shear off the deposited materials and thus reduce the hydraulics resistance of the fouling layer. An optimum value of air flow rate was identified beyond which further increases had no effect. The similar phenomenon was also verified by some researchers. Wang (2012) investigated the effect of hydrodynamic on biomedia and concluded that the treatment filtration rate sharply increased at aeration intensity below the critical aeration intensity. |

Moving Bed Biofilm Reactor (MBBR) There are varieties of biomedia used in river water purification technologies which are available in the local and international water industry market nowadays, and the types of biomedia can be characterized by considering the types of treatment system. Different types of biomedia have their unique performance based on certain treatment conditions. Apart from biomedia removal efficiency and physical characteristics at the allocated design flow, other important aspects that affect the decision in selection of biological carriers for MBBR and IFAS are frequency of maintenance and cost. Biomedia should be able to provide a habitation for the growth of the attached microorganism which is called biofilm layer, either fixed or freely moving inside the river purification system. Based on previous studies, Biomedia in MBBR and IFAS have been widely tested only for domestic sewage or industrial wastewater including aquaculture wastewater. However, approaches of this kind carry with them various well known limitations. There have been no controlled studies which compare differences between biomedia physic-chemical and biological performance for river water treatment plant in local tropical river condition. However, the research concluded so far are compiled herein and reported for the first time to acquire a better perspective and insight on the subject with a view of meeting the news approach. To this end, the most feasible technology could be the combination of advanced biological process (bioreactor systems) including Moving Bed Biofilm Reactor (MBBR) and Integrated Fixed Activated Sludge (IFAS) system. |
