The Fall 2016 UASB team is looking to further progress the research conducted by previous teams. The reactors were kept running over the summer by the diligent work of Andrew Kim, so time will not be spent on inoculation. Instead the team will focus on optimizing reactor performance by upgrading the gas measurement system and increasing air tightness. The experiments conducted by the team this semester will include testing the reactors ability to degrade high strength wastewater such as backwater. The HRT of wastewater flowing through the settled bed will also be measured this semester. The team plans to characterize reactor performance through the use of GC, COD, pH, and VFAS analysis. Once sufficient data is recorded, comparisons to wastewater in Honduras will be made and models will be developed to determine feasibility of implementation in Honduras.
Spring 2017
The Spring 2017 will determine our goals and objectives soon,During January 2017, a proposal for a novel UASB reactor was submitted to the Environmental Protection Agency P3 competition. This novel UASB reactor would be prefabricated, operated electricity-free, and affordable for small communities in the global south. Two innovative components of this UASB reactor is the submerged lid and plate settlers. The Spring 2017 UASB team tested the efficiency of these two elements and found that the submerged lid has the capacity to be gas-tight and therefore should be part of the UASB reactor. However, the results of the plate settler tests were inconclusive and the test should be repeated to determine if plate settlers improve solids (granule) retention.
