Our team is working on finalizing the design for the point-of-use foam filtration unit. Different designs for the filtration unit are being considered and researched thoroughly. Most of the work we have done thus far is focused on the specific design of the alum doser and methods of incorporating this dosing component into the overall system. An Initially, a "continuous" dosing design was proposed, but due to many problems associated with the design, the team decided to instead go with a "batch" dosing system, whereby the user would manually add alum and chlorine into the holding tank and distribution tank respectively and then stir. An analysis of each proposed design for this dosing unit the filter was conducted using MathCAD in order to determine its feasibility from a quantitative standpoint. By the end of the semester, we hope to have concrete dimensions and parameters for each individual component within the system. Afterwards, we plan to construct and test our design.Update this summary. There were plans to fabricate a prototype of the filter by the semester's end, however, plans to refocus on the revisions of a research paper have prevented this from happening.
Head Loss Calculations
Research from fall 2010 was continued in hopes of determining the head loss through foam as a function of filter run time. We were also interested in determining the head loss at filter collapse.
