“…The media is kept within the reactor volume by an outlet sieve or screen, which may be vertically mounted, rectangular mesh sieves, or cylindrical bar sieves, vertically or horizontally mounded. The media most often used is made of high density polyethylene (density 0.95 g/cm3) and shaped as a small cylinder with a cross on the inside of the cylinder and 'fins' on the outside [21,22]. Suhr and Pedersen [23] compared nitrification performance in submerged fixed bed biofilters (FBB) and moving bed biofilters (MBB).…”

“…Another advantage of MBBR arises here; its filling fraction in the reactor is subject to preferences. Recommended filling fractions should be less than 70% so that the biofilm carrier suspension can move freely [9]. Like the activated sludge system, MBBR uses the whole reactor, but does not require sludge cycle.…”

Abstract. The pilot-scale experiment in moving bed biofilm reactor (MBBR) with a capacity of 433 L was carried out for this study with real life situations, it was decided that the complete research work must be done under as realistic conditions as possible, i.e. with real municipal wastewater, chemical free and with local commercially available products such as carriers for biofilm reactor. The reactor was start-up in 30/9/2013 up to date, Effluent from clarifier of STP used as influence of MBBR for polishing. MBBR is using continues down flow to polish effluent municipal wastewater from a faculty of new building engineering community in UKM to get the water free from main pollutant parameters, for reuse in the irrigation or discharge to the river. Laboratory experiments will conduct with different hydraulic retention time (HRT), filling ratio of plastic (Enviro Multi Media) in the MBBR about 5%. Aerobic reactors used the majority of the decaying organic material. An average removal rate of 41.75%, 32.85%, 24.80% and 35.77% of initial chemical oxygen demand (COD) were achieved under a HRT of 24hr, 12hr, 6hr and 2hr, respectively. The model simulated results showed good agreements with experimental results. The model could be employed in the design of a full-scale MBBR process for simultaneous removal of organic carbon from effluent STP.

“…Air blower and ventilation then needs to be installed. Moving bed bioreactor (MBBR) can be either operated as an aerobic process (nitrification) or anoxic and anaerobic processes [51].…”

Designing aquaculture production units will require decisions on which treatment to include, e.g., the intensification of the system, and then a decision on a technical solution for each treatment function selected to implement. To complicate matters, each technical solution is not unique to each treatment function, but has a multiple effect on the system. This interaction of a technical solution to multiple treatment functions will play a part in the decision making process. Previous work by the authors has made a taxonomy of all technical solutions for the treatment function, and in this article, how technical solutions affect treatment functions is mapped. The article views the aquaculture production system as a transformation process with three sets of functions, input, treatment and output. Based on a comprehensive literature review where all technical solutions were found and categorized into a taxonomy, their effect on treatment function was mapped using a quality function deployment (QFD). The result is a matrix that gives an evaluation on the interaction. This work is a step towards an aquaculture engineering design methodology.
