500 Gallon Bio filter. MMB35 for aquaculture

These are massive aquaculture bio filters. In the photo you can see a 2’ measure for reference. Made by Aquatic ED these are premier filters for massive scale. Over 6’ tall and 47” wide. I have 3 of these and they are in great condition with only a few months of light use. The bulkhead ports on the sides are 6” fittings. I also have pentair pumps available separately to power these. 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.
