| Abstract | In this work, the start-up and operation of a pilot-scale sewage treatment plant are described. The plant consists of two UASB (upflow anaerobic sludge blanket) reactors in series followed by five waste stabilization ponds (WSP), also in series. The start-up was accomplished in approximately one month. Chemical oxygen demand (COD) removal efficiency in the anaerobic steps reached 90%, with hydraulic retention times (HRT) of 6 + 6 h, while total and volatile suspended solids (TSS/VSS) removal was 98,1 and 99,1%, respectively. Faecal Coliforms (FC) removal in the entire system was 99.9999%, with 15 d HRT in the WSP. Total removal of helminth eggs was 99.3%. The studied system is an attractive option for sewage treatment in subtropical regions. |
