Microbiological Study of a Bleached Kraft Pulp Mill Aerated Lagoon
نویسندگان
چکیده
Pulp mill aerated lagoons are subject to perturbations owing to the chang-ing composition of the effluent and variations in climate. Such stresses may affect microbial activity and the biodegradation of chlorinated organic compounds. Studies revealed thatvariation in the culturable microbial population in a northern Ontario kraft pulp mitl la-goon is related to process parameters (wood type and temperature). Although organochlorine removal was found not to vary seasonally in a previous study of the same la-goon, the occurrence of lagoon effluent toxicity during the winter months correspondedwith declining temperature and numbers of viable bacteria in the aeration stabilization

Organic compounds present in the bleached kraft pulp mill (BKPM) effluents may be reduced by biological treatment like: activated sludge (AS) or aerated lagoon (AL). However, after biological treatment, BKPM effluent still contains specific compounds. Some of them have been related with chronic effects (DNA damage, reproductive and physiological) observed on fishes exposed to BKPM effluents. Th...

K raft pulp is manufactured in the United States from nearly all commercially availble wood species. About 55 million tons per year are manufactured, 30 million of which are bleached and used mostly for printing and office papers and tissue products. Some kraft pulp is exported, and significant quantities are imported, mostly from Canada and South America. Pulps manufact'xed by sulfite, ...

متن کاملImproved aerobic biodegradation of abietic acid in ECF bleached kraft mill effluent due to biomass adaptation.
Kraft pulp mill effluents contain elevated concentrations of resin acids, chiefly abietic and dehydroabietic acid, and other lipophilic wood constituents. Resin acids, if not efficiently removed during wastewater treatment, can be responsible for chronic toxicity in aquatic systems. The objective of this study was to investigate the biological removal of abietic acid (AbA) during the treatment ...
