The Channel GRU is a grit removal unit, similar to the one described above, that is instead placed at the very entrance of the flocculator. bundle of evenly spaced plate settlers, similar to those in the sedimentation tank, .Using the same fundamental design parameters as the Channel GRU, the Entrance GRU is a bundled set of closely-spaced plate settlers. However, as the name implies, the GRU would be placed within the entrance tank, which in our previous designs was just vestigial unit. A sketch of our most recent design of the Channel GRU is shown in the diagrams below.
Figure 3.a. Top view of a flocculator with a GRU at the entrance of the first flocculator channel. The entrance tank, like in the GRF channel design, will only consist of vestigial elements, such as the trash rack.
