Performance of anaerobic filters using bamboo as support Material in the swine wastewater treatment

Abstract

The objective of this study was to evaluate the performance of anaerobic filters containing
bamboo cuts as a support material, in comparison with anaerobic filters containing gravel, in
the treatment of swine wastewater. The experiment was carried out in a randomized completely
design, with 2 treatments (gravel and bamboo), 3 replicates , in split plot.), The filters were
operated with upflow, with a capacity of 5.1 L each and a hydraulic holding time of 12 hours.
In order to evaluate the efficiency of the filters, turbidity, total solid, suspended solids, total
nitrogen and Biochemical Oxygen Demand analyzes were performed in the effluent and filter
effluent, every 7 days. The anaerobic filter containing bamboo cuts showed good removal efficiency
in most attributes evaluated, being an alternative for the treatment of swine wastewater.
