Abstract
In accordance with the present invention there is provided a dual manifold filtering system. The dual manifold filtering system of the present invention, unlike the currently available filtering systems, allows the filter elements to be cleaned from both ends of the filter elements during backwashing operations. A flow restriction device is also placed in the grid main channel of the filter elements to force more of the liquid to flow out radially from the grid main channel during backwashing. Valve and piping means are provided to enable liquid to be directed into one or the other manifold during backwashing operations.
