effect of temperature on anaerobic treatment of black water in uasb Septic Tank systems
Bioresource Technology, 2007Co-Authors: Sari Luostarinen, W T M Sanders, Katarzyna Kujawaroeleveld, G ZeemanAbstract:Abstract The effect of northern European seasonal temperature changes and low temperature on the performance of upflow anaerobic sludge blanket (UASB)-Septic Tanks treating black water was studied. Three UASB-Septic Tanks were monitored with different operational parameters and at different temperatures. The results indicated the feasibility of the UASB-Septic Tank for (pre)treatment of black water at low temperatures with respect to removal of suspended solids and dissolved organic material. Inoculum sludge had little effect on COD ss removal, though in the start-up phase some poorly adapted inoculum disintegrated and washed out, thus requiring consideration when designing the process. Removal of COD dis was at first negative, but improved as the sludge adapted to low temperature. The UASB-Septic Tank alone did not comply with Finnish or Dutch treatment requirements and should therefore be considered mainly as a pre-treatment method. However, measuring the requirements as mgCOD l −1 may not always be the best method, as the volume of the effluent discharged is also an important factor in the final amount of COD entering the receiving water bodies.

low flow water quality in rivers Septic Tank systems and high resolution phosphorus signals
Science of The Total Environment, 2011Co-Authors: Katrina A Macintosh, Joerg Arnscheidt, Philip Jordan, Rachel Cassidy, C. WardAbstract:Rural point sources of phosphorus (P), including Septic Tank systems, provide a small part of the overall phosphorus budget to surface waters in agricultural catchments but can have a disproportionate impact on the low flow P concentration of receiving rivers. This has particular importance as the discharges are approximately constant into receiving waters and these have restricted dilution capacity during ecologically sensitive summer periods. In this study, a number of identified high impact Septic systems were replaced with modem sequential batch reactors in three rural catchments during a monitoring period of 4 years. Sub-hourly P monitoring was conducted using bankside-analysers. Results show that strategic replacement of defective Septic Tank systems with modern systems and polishing filters decreased the low flow P concentration of one catchment stream by 0.032 mg TP L(-1) (0.018 mg TRP L(-1)) over the 4 years. However two of the catchment mitigation efforts were offset by continued new-builds that increased the density of Septic systems from 3.4 km(-2) to 4.6 km(-2) and 13.8 km(-2) to 172 km(-2) and subsequently increased low flow P concentrations. Future considerations for Septic system mitigation should include catchment carrying capacity as well as technology changes. (C) 2011 Elsevier B.V. All rights reserved.
