Abstract
A bar grid is formed with multiple vertical rods supporting multiple horizontal roll formed elements with a flange at a front edge of each element. The grid is mounted in a water effluent stream on each side of a solid filter screen or grinder and funnels solid material down to the compactor without buildup of solids on the grid screen.
Claims7
A static bar grid located in the down stream flow of a water effluent stream comprising
- multiple closely spaced apart horizontal roll formed flat metal bars supported by vertical rods to form a grid panel, a front edge of each horizontal bar having a flange to create a diminished space between the horizontal bars in relation to the space between the remainder of each horizontal bar,
- multiple grid panels being attached together and located on each side of the effluent stream to form a funnel configuration with a wide mouth of the funnel upstream and a narrow end downstream leading to a solid waste compactor,
- the panels in the funnel configuration being at an angle of less than twenty degrees to the solid waste compactor and
- means for supporting the grid panels in the water effluent stream.
