Longitudinal grit chamber and grease trap combination for e.g. sewage treatment plant, has flow roll in grit chamber that is connected with grease trap via openings, where grease trap is divided by intermediate wall in separate bowl section

摘要

The combination has a flow roll (8) in a grit chamber (1) that is connected with a grease trap (2) via openings (4). The grease trap is divided by an intermediate wall (9) in a separate bowl section, where the intermediate wall is arranged over the length of the grease trap. The openings are partially closed with lamellae and extend between the intermediate walls. The openings are arranged such that the dimension of the flow roll in the bowl section can be varied through mechanical input.
