Upflow Anaerobic Sludge Blanket (UASB)
The Fall 2015 Upflow Anaerobic Sludge Blanket (UASB) group has continued the previous work of the AguaClara anaerobic wastewater groups. Challenges addressed during this and next semester include testing reactor leakage and creating an airtight design, combining a UASB unit with a GSBR unit in an attempt to improve overall treatment capacity, and oxygen stress testing to determine the robustness of the reactor. The beginning of the semester was spent cleaning and removing biomass from reactors, testing for leaks using a bubble solution, and performing a single-day pressure test in an attempt to approximately quantify the volumetric leakage rate. Two UASB reactors were inoculated and began producing biogas within the first week of operation. COD analysis and gas chromatography were performed to characterize the efficiency of COD treatment and methane production within the reactors. UASBs are part of AguaClara's wastewater program, which is working to expand wastewater treatment programs in rural areas in Honduras and future AguaClara work sites. Fall 2015
