Clearwater™ Low-Space BioreactorFully automatic, self-adjusting and continuously self-cleaning!
There are many types of biofilters used in aquaculture, including trickling, submerged, rotating biological contactors (RBC) and fluidized beds. AES offers the revolutionary Clearwater™ Low-Space Bioreactor (LSB). While other biofilters manage an average of 3 kilograms of feed per cubic meter of biofilter volume per day, the LSB manages as much as 12 kilograms of feed per cubic meter. That's 440 grams of total ammonia-nitrogen (TAN) per cubic meter of media per day. Our smallest LSB will handle a standing stock of fish up to 140 pounds.
This is a robust, nonpressurized biofilter that is much less sensitive to flowrate variations and power interruptions than fluidized bed sand biofilters. When operated in low-head recirculating systems, it can easily be sunk into the floor to reduce the pump pressure. When installed this way, only a few inches of head loss will occur across the LSB. Because air is used to circulate the media, the LSB both adds oxygen and strips carbon dioxide! A hood can be placed over the bioreactor to vent the CO2 outdoors. We have colored them blue/green to prevent algae growth inside and provide the dark environment preferred by the Nitrobacter bacteria.
Air diffuser depth can be adjusted for compatibility with your blower/compressor. The LSBs are complete with media. Compressed air connections are 1/2" slip. Air pump not included. All you need are male-threaded pipe connections. We can also custom-build larger sizes. |
