Clearmont, Wyoming
Mark Court Certified Wastewater Specialist U.M.C.
(Retired)
In a 2022 Independent Study conducted by Mark Court, Wyoming Association of Rural Water Systems, from four different lagoon systems in four different regions of the state. His findings were as follows:
| Run Time | 157.25 hrs |
| Cubic yards removed | 74 y3 |
| Tonnage Removed | 28.88 tons |
| Nitrogen Removed | 2599-5776 lbs* |
| Phosphorus Removed | 1155-2599 lbs** |
**Based off 2% to 4.5% found in duckweed.
- Run Time: 157.25 hrs.
Cubic Yards Removed: 74 y3
Tonnage Removed: 28.88 tons - Nitrogen Removed: 2599 – 5776 lbs. (Based off 4.5% to 10% typically found in duckweed).
- Phosphorous Removed: 1155 -2599 lbs.(Based off 2% to 4.5% typically found in duckweed).
By removing the duckweed from these systems, it prevented the seeds from becoming apart of the sludge blanket, which effectively translated to cost savings in sludge removal. Based on the $850 per dried sludge ton, the cost savings of the sludge prevention equates to $4240 – $7420!
