Comparison of novel membrane bioreactors and constructed wetlands for treatment of pre-processed animal rendering plant wastewater in cold climate

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. (Reedmace or Broad-leaved Cattail). The process wastewater followed pre-treatment by dissolved air flotation (DAF). The DAF effluent gave highly variable chemical oxygen demand (COD) and ammonia concentrations of 5816 (± 3005.0) and 614 (± 268.7) mg/L, respectively. The MBR effluent for COD and ammonia was 37 and 86 mg/L, respectively. The treatment performance of the constructed wetland for COD, ammonia and suspended solids was 205, 67 and 57 mg/L, respectively.
