چکیده انگلیسی
The Waterman Ecological Treatment System (WETS) had four replicate treatment lines. Together, the four lines treated 1310 L/day of diluted wastewater from a dairy facility with over 99% removal of ammonium-nitrogen (NH4-N) and carbonaceous biochemical oxygen demand (CBOD), and 79% removal of orthophosphate (PO4-P). The average influent/effluent concentrations of NH4-N, CBOD, and PO4-P were 52.1/0.07 mg/L, 517/5.2 mg O2/L, and 21.0/4.4 mg/L, respectively. Nitrate + nitrite (NOx-N) was produced and removed within the system, and had an average effluent concentration of 0.53 mg/L. The multiple anaerobic-aerobic interfaces in the WETS design enhanced biological removal of nitrogen and phosphorus. NH4-N, CBOD, and NOx-N were consistently removed throughout the 20-week study, but PO4-P removal efficiency decreased over time in one of the four treatment lines.
