    Abstract

    The performance of a novel industrial membrane bioreactor (MBR) comprising denitrification, nitrification and ultrafiltration for the secondary treatment of primary treated animal rendering wastewater has been compared with an experimental, low-cost and novel vertical-flow constructed treatment wetland planted with Typha latifolia L. The process wastewater followed pre-treatment by dissolved air flotation (DAF). The DAF effluent gave highly variable chemical oxygen demand (COD) and ammonia of 5200 (± 2050) and 490 (± 270) mg/l, respectively. The MBR effluent for COD and ammonia was 45 and 63 mg/l, respectively. The treatment performance of the constructed wetland for COD, ammonia and suspended solids was 167, 63 and 15 mg/l, respectively.
