This moving media biofilter manages as much as 12 kilograms of feed per cubic meter. Which equals 440 grams of total ammonia-nitrogen (TAN) per cubic meter of media per day. The MMB is a non pressurized biofilter that is much less sensitive to flow rate variations and power interruptions than fluidized bed sand and trickle style biofilters. When operated in low-head recirculating systems, it can easily be sunk into the floor to reduce the pump pressure. If installed this way, only a few inches of head loss will occur across the MMB. Because air is used to circulate the media, the MMB both adds oxygen and strips carbon dioxide. A hood can be placed over the bioreactor to vent the CO2 outdoors. Air diffuser depth can be adjusted for compatibility with your blower/compressor. MMB’s come complete with media. Compress air connections are ½” slip. Air pump is included. We can also custom build larger sizes. Part Number Tank Vol (Gal) DxH (Inches) Media Max.
