Abstract:
1. A filter separator apparatus for removing particles and organisms from liquid comprising: a conical inlet chamber, a separation and filter chamber, and a discharge chamber with a sludge outlet, the chambers connected along a common axis and together defining a liquid flow path; an inlet back flushing pipe, a screen filter and a lower outlet pipe aligned along said axis with the upper outlet positioned within the conical inlet chamber, the screen filter within the separation and filter chamber, and the lower outlet pipe within the discharge chamber; the conical inlet chamber having a tangentially mounted inlet pipe to establish a helical circular motion of entering liquid with the liquid accelerating in said helical motion without forming a vortex as the liquid moves along the conical chamber into and through, the separation and filter chamber; whereby particles and organisms of specific gravity greater than that of the liquid are carried by the liquid through the separation and filter chamber into the discharge chamber to the sludge outlet, and particles and organisms of specific gravity near to that of the liquid are filtered from liquid passing through the filter screen so that liquid purified of particles and organisms is discharged from one of the upper and lower outlet pipes depending on the installation concept.
