Abstract

The Brookings Wastewater Treatment Facility is authorized by a National Pollutant Discharge Elimination System (NPDES) Permit No. SD-002338 to discharge treated wastewater to the Big Sioux River. A summary of this permit can be found in Table 1. To provide proof of compliance with the NPDES Permit, periodic sampling and analyses of the treated effluent is required. Primary sample points at the Brookings Wastewater Treatment Plant (BWWTP) are located a at the influent to establish raw wastewater concentrations and at the effluent to determine compliance with NPDES Permit discharge parameters. This sampling regime also provides information on the overall plant performance and removal efficiency of typical domestic wastewater concentrations. Although this sampling procedure does provide the necessary information for proof of compliance with the NPDES Permit, it does not provide sufficient data to evaluate the individual performances of the various treatment. processes throughout the plant. The objectives of this study were to: (1) determine if the nitrification process at the BWWTP is operating as a separate stage or combined ammonia-nitrogen removal process, based on the magnitude of the kinetic coefficients; (2) evaluate the nitrification kinetic coefficients at the BWWTP and compare them with values reported in the literature; (3) provide a basis of information and suggestions for future research to insure optimum performance of the air activated sludge nitrification system.
