This week our team has been putting in werk, my apologies work for our prototype inspection day and video. In the past, we have had comments that people do not understand what we’re selling. Thus, we thought to make a mini physical model of our solutions. Even though our project is more related to the system and cost, it is important to understand how it works. We used two fish tank pumps, one for each solution. The pellet reactor was composed of 75% a plastic water bottle with BBs to simulate the fluidized bed function of it. A fluidized bed is essentially when the solid particles in a reactor almost behave like fluid. We demonstrated this by pumping the water in from where the BBs were lying flat. With the water pumping up, the BBs shoot up and come doing in a repetitive motion. This represents the sand that gets shot up and interacts with the calcium in the water and then falls in a new pellet form. The physical model of the ion exchange tank is a little simpler: a plastic peanut butter jar was used with BBs. The water came in from the top of one side and came out the other end. The BBs sit in the bottom making up about half the jar with little to no movement. This is what would occur in an actual ion exchanger tank as the BBs represent resin beads that would absorb the calcium in the water.
