Troubleshooting Bnr Processes

چکیده
Most biological nutrient removal (BNR) wastewater treatment plants are required by permit to significantly reduce total nitrogen (TN) and total phosphorus (TP). In Florida, advanced wastewater treatment (AWT) permit limits are as stringent as 3 mg/L TN and 1 mg/L TP as annual average or maximum month values. Consistently meeting low nutrient permit limits presents several operational challenges. Optimizing removal of TN and TP requires an understanding of where these compounds originate, their concentrations, the processes designed to reduce them, and the interaction of components within the process and treatment facility.

The Effect of High Temperatures on Bnr Process Performance
The ever-expanding world-wide application of biological nutrient removal (BNR) technology is generating a greater appreciation for the performance of BNR processes under different operating conditions. This paper examines the effects of high process temperature on the biological phosphorus and nitrogen removal mechanisms and the sludge settling properties in BNR activated sludge processes. Thes...
متن کاملFilamentous Chloroflexi (green non-sulfur bacteria) are abundant in wastewater treatment processes with biological nutrient removal.
Most filamentous bacteria in biological nutrient removal (BNR) processes have not been identified beyond their morphotype and simple staining reactions. Furthermore, the majority of sludge filaments observed under the microscope do not hybridize to commonly used phylogenetic probes for well characterized bacterial phyla such as the Proteobacteria, Actinobacteria, Firmicutes and BACTEROIDETES: S...
متن کاملN2O emissions from activated sludge processes, 2008-2009: results of a national monitoring survey in the United States.
Despite recognition of the possible role of biological nitrogen removal (BNR) processes in nitrous oxide (N(2)O) emission, a measured database of N(2)O emissions from these processes at the national scale does not currently exist. This study focused on the quantification of N(2)O emissions at 12 wastewater treatment plants (WWTPs) across the United States using a newly developed U.S. Environmen...
متن کاملEffects of A2ON Process on Denitrifying Dephosphatation
In combination with activated sludge process and biomembrance process, based on the principle of denitrifying dephosphatation, A2ON processes for biphase sequencing batch reactor biological nutrient removal (BNR) treatment have been developed, with an emphasis on the effects of the ratio of COD to TN (COD/TN) variations on the BNR treatment. Results indicated that the process possessed stable e...
متن کاملA Proposal to Combine Probabilistic Reasoning with Case-Based Retrieval for Software Troubleshooting
Analysis of a real case of software troubleshooting made it clear that probabilistic models, or Bayesian networks are suitable for modeling software troubleshooting processes in today’s computing environments. As a way to support software troubleshooting by reusing skillful support engineers’ expertise, I propose to use Bayesian networks and probabilistic reasoning for case-based retrieval. The...
