Abstract

A full-scale sequencing batch reactor (SBR) was installed to treat the milking center wastewater discharged from the milk house on a dairy farm which was a typical small-size dairy producer with 100 cows. The total volume of the reactor is 5760 liters (1500 gallons) while the working volume is 3402 liters (900) gallons. Two cycle regimes with total cycle time of 12 hours were designated to test the performance of treatment during the start-up period, Regime 1 was with aerobic-anaerobic REACT, and Regime 2 with anaerobic-aerobic REACT, both operated under an HRT of three days without wasting sludge. Regime 1 was running for one and half months before the steady state was observed, and the removals of TS, VS, BOD, NH4-N, TKN, TP, DP were 44.6%, 69.4%, 94.6%, 100.0%, 83.5%, 24.1%, 47.7%, respectively. Regime 2 was established at a lower sludge level, thus needed longer time to get to steady state. Results showed that the regime with anaerobic-aerobic REACT was more supportive of phosphorus removal than that with aerobic-anaerobic REACT.
