I am advising the fluoride and public relations teams, and working as part of the High Rate Sedimentation - Plate Settlers team this semester. Sedimentation is the process that requires the largest plane view area in a water treatment plant, and this is due to the necessary slow upflow velocity to allow particles to fall down. In hopes of overcoming that obstacle, the two high rate sedimentation teams this semester are looking at ways of concentrating the floc blanket to permit this higher upflow velocity. The team I am a part of this semester will focus on using plate settlers in the floc blanket to concentrate floc particles.
Fall 2015 Contributions
I am advising the ram pump , and StaRS Theory teams, and working as part of the EStaRS team this semester. The EStaRS filter currently has orifices in the inlet manifolds, which has not previously been tested in a full scale filter. This semester, we are looking to fine tune the filter for backwashing and verify that orifices are an effective method of fabrication. If all goes well, we plan on modeling head loss through the sand bed at various turbidities of influent water.
