The RMCC team was created to address high coagulant loss in the Rapid Mix tube and create an alternate design for Rapid Mix to happen. Our goals this semester are to design and build a contact chamber to add to the Rapid Mix process and research how this chamber will affect the Rapid Mix efficiency and coagulant losses. This semester the team will vary geometry and residence time to find the best design for this chamberRapid Mix Contact Chamber team worked to build a contact chamber that allowed for the rapid mixing of raw water and coagulant, improving upon the existing Rapid Mix Tube by providing a larger volume for mixing to take place. The goal of the team was to determine the shape of the contact chamber that would result in the least coagulant loss and to determine the residence time needed to maximize mixing but minimize coagulant loss. The team used mass balance to determine the loss of coagulant to the flocculator walls and used pigging to clean the flocculator in between trials.
