Fully automatic, self-adjusting and continuously self-cleaning
This is a robust, nonpressurized biofilter that is much less sensitive to flow rate 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 CO2outdoors. 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. 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. Ships motor freight.
