Abstract

Cellular adenosine triphosphate (cATP ™ ) may be used to characterize the biological degradation activity within the anaerobic and aerobic wastewater treatment systems. The feasibility of using cATP ™ as a process monitoring parameter for an anaerobic membrane bioreactor was evaluated. Results obtained from batch respirometric anaerobic treatability studies and a continuous sludge-bed anaerobic membrane bioreactor (SB-AnMBR) treating prehydrolysis liquor were examined. Both studies were conducted at an operating temperature of 35 °C. The batch studies indicated that the indirect activity measurements, such as the methane production rate correlated well with cATP ™ . The cATP ™ content of the SB-AnMBR responded to changes in total amount of degraded chemical oxygen demand (COD) and methane produced with correlation coefficient of 0.91 and 0.80, respectively. In contrast, cATP ™ was not well correlated to mixed liquor volatile suspended solids with correlation coefficient of 0.52. The values of cATP ™ /COD removed ratio and active biomass ratio (ABR ™ ) indicated that the increase in cATP ™ value might be a result of increased biodegradation activity in the SB-AnMBR system.

期刊介绍： The Water Quality Research Journal publishes peer-reviewed, scholarly articles on the following general subject areas: Impact of current and emerging contaminants on aquatic ecosystems Aquatic ecology (ecohydrology and ecohydraulics, invasive species, biodiversity, and aquatic species at risk) Conservation and protection of aquatic environments Responsible resource development and water quality (mining, forestry, hydropower, oil and gas) Drinking water, wastewater and stormwater treatment technologies and strategies Impacts and solutions of diffuse pollution (urban and agricultural run-off) on water quality Industrial water quality Used water: Reuse and resource recovery Groundwater quality (management, remediation, fracking, legacy contaminants) Assessment of surface and subsurface water quality Regulations, economics, strategies and policies related to water quality Social science issues in relation to water quality Water quality in remote areas Water quality in cold climates The Water Quality Research Journal is a quarterly publication. It is a forum for original research dealing with the aquatic environment, and should report new and significant findings that advance the understanding of the field. Critical review articles are especially encouraged.
