This
paper examined the ability of Penicillium camemberti
to degrade hemp-based pulp and paper plant bleachery
effluents in batch and up-flow column reactor studies. In
batch tests, the highest removals for acid-line effluents
(67% AOX (adsorbable organic halogens), 44% TOC 8 total
organic carbon), 97% color) were obtained with 2 g/l acetate
concentration in 10 days. Acid-line and alkali-line
composite effluent was also fed to a column reactor with of
17 mg/l. AOX concentration. In column studies, the highest
removals (57% AOX, 67% TOC, and 74% color) and (57% AOX, 48%
TOC and 73% color) were obtained with 0.5 and 0.2 g/l feed
acetate concentration in 20 days, respectively. Gas
chromatography analysis indicated drastic reductions at low
molecular weight adsorbable organic halogen compounds.
Key
words:
