| parameter | value |
| diameter | 8mm |
| depth | 6mm |
| surface area ( approx.) | 800 square meters/cubic meter |
| specific gravity | 0.95 |
| material | polyethylene |
| air flowrate per cubm of media | 10 cubm/hr |
| water flowrate per cubm of media | 20 to 40 cubm/hr |
| biomass loading per cubm of media | 250 to 500 kg |
| ammonium loading per cubic metre of media | 0.5 to 1 kg of ammonium per day |
| Organic loading ( feed level given to fish) per cubm of media | 20 to 40 kg feed/day |
| BOD loading (approx) | 20 kg/cubm/day |
With regards to the water flowrate and biomass loading, there is degree of variation with regards to these values. The feed level given relates to the amount of fish feed given to the fish each day. The value also assumes that the feed is not wasted, and that there is good mechanical water filtration in the system.
In addition to the media, Dryden Aqua can provide a complete biofiltration system comprising f the the biofilter tank and aeration equipment. The biofilter are constructed from rotationally molded tanks and are available is sizes up to 40 cubic metres capacity..
