Species you are culturing: |
|
Make-up Water Source:
We are assuming that clean source water is used, low in nutrients and without unusually high mineral concentrations. If in doubt, send a water sample to a reputable laboratory and fax us the results. |
Where does your water come from (city, well, reservoir, etc.)?: |
|
Make-up water flow rate: |
% of total volume replaced per day. |
Temperature range: |
°F to
°F. |
Maximum sustained pH (12-hour period): |
|
Note: High pH = high un-ionized ammonia (NH3) = low allowable total ammonia (TAN) = reduced nitrification = bigger biofilter. |
Dissolved oxygen concentration of water entering the biofilter: |
mg/l |
Total system water volume treated by biofilter: |
gallons |
Nitrogen Loading: |
Individual average body weight at harvest time: |
lbs, or
grams |
Maximum number of animals served by the biofilter at time of harvest: |
|
Typical feed rate prior to harvest: |
percent of body weight per day. |
Feeding frequency prior to harvest (give times of day): |
|
Feed protein content: |
percent |
Feed type (describe): |
|
Solids Filtration: Fish waste must be filtered out prior to the biofilter. This will reduce biofilter fouling and heterotrophic bacterial activity. |
Solids removal system (describe): |
|
Solids, size filtered: |
microns |
Biofilter Type Preferred |
Bead (Bio-Clarifier) Fluidized Sand. |
Rotating Biol. Contractor (RBC) |
Low-Space Bioreactor (Moving Bed) |
Trickle |
Fluidized Sand. |

If you have information on one-pass total ammonia nitrogen (TAN) removal efficiency for the biofilter type you wish to use, please specify: |
percent |
Describe the water quality conditions under which this one-pass ammonia removal was achieved: |
|
Further describe your system and biofiltration requirements |
|
If possible, please provide us with the feed chart you intend to use for your species based on weight and water temperature. |
Note: Our calculations are based on standard aquacultural engineering methods and current scientific studies. |
