"May 1971." "DWR-WOO Grant No. 13030 ELY; DWR-USBR Contract No. 14-06-200-3389A." "The agricultural drainage study was conducted under the direction of: Robert J. Pafford, Paul De Falco [and] John R. Teerink." Includes bibliographical references (page 27). |
| Contents Notes |
Studies have shown that it is technically feasible to reduce 20 mg /l nitrate-nitrogen in agricultural tile drainage to 2-5 mg/l by either algae stripping or bacterial denitrification. Conditions necessary for maximum algal growth included 8- to 12-inch pond depth, addition of small amounts of nutrients (CO2, Fe, and P), up to four hours of daily mixing and detention times of from 5 to 16 days, depending on the season. The algae were harvested by coagulation-sedimentation followed by vacuum filtration. Bacterial denitrification was tested in anaerobic deep ponds and filters using methanol as a carbon source. Required detention times were on the order of 8 to 50 days for covered ponds (uncovered ponds were not suitable) and 1 to 2 hours for filters. Preliminary cost estimates are given. Laboratory studies indicated that nitrogen removal effectively lowered the biostimulatory nature of the waste with respect to algal growth in potential receiving waters. Two desalination processes were also studied -- electrodialysis and reverse osmosis. |
