Denitrification by anaerobic filters and ponds | Bio-engineering aspects of agricultural drainage, San Joaquin Valley, California
1972
Jones, James R.
Operational criteria, design and operations costs for a treatment facility to remove nitrogen from agricultural tile drainage in the San Joaquin Valley were further investigated during 1970 at the Interagency Agricultural Wastewater Treatment Center near Firebaugh, California. The year-long study period is identified as Phase II. Based on projected nitrate-nitrogen concentrations for valley tile drainage water, the research in this phase extended earlier Phase I studies on the feasibility of bacterial denitrification by filters and covered ponds.
