Accordingly, the work presented here assesses the
performance of APs treating wastewater from tapioca
starch industry, particularly related to COD, TSS and
cyanide removal. Since APs serve as a settling basin for
starch granules, the settling characteristics were also
assessed by column experiments. Furthermore, the potential
methane production rates of anaerobic biomass
(sludge) obtained from the AP sediment as well as from
bulk liquid layer were assessed from the specific methanogenic
activity (SMA) test. The cyanide degradability
of the anaerobic sludge obtained from the pond sediment
layer was also assessed.
