FTTFC (Spring 2016)
Conducting backwash of filters required high flow rate. During low flow conditions, the required flow rate is achieved by redirecting flow from the other filters into the one being backwashed. The objective for the Filter and Treatment Train Flow Control team (FTTFC team) this semester was to design and construct a weir module that would allow the plant operator to easily redirect sufficient flow for filter backwash without shutting off other filters’ flow, and without requiring calculations done by the plant operator. The goal of the design was to be easily constructible, easy to operate, strong enough to withstand water pressure and require no calculations for plant use.
