This semester, Bonnie and I continued Tori's work on high flow modifications for AguaClara plants. We considered the constraints on achieving macro- and micro-mixing in the rapid mix channel for high flow plants. I helped write code to determine the geometry of the rapid mix channel. We then calculated the headloss through the channel, as well as the dimensions for a micro-mix orifice sheet and micro-mix gates (of PVC pipes, steel or aluminum bars).
