| 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. |
