Novel membrane bioreactors and constructed wetlands for treatment of pre-processed animal rendering plant wastewater in Scotland

Scholz, M

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.
