    Abstract: A filter unit for filtering particulates and other foreign matter from a water supply, comprising a filtering chamber. At least a portion of an exterior of the filtering chamber being provided with filtering chamber in use. The mesh being sized to filter particulates and other foreign matter from the water. The filter unit further comprising an outlet through which filtered water exits the filter unit, and a rotatable member located within the filtering chamber, the rotatable member having at least one outlet spaced from an internal face of a mesh. The axis of rotation of the rotatable member being such that the at least one outlet traverses at least a substantial portion of the internal face of a mesh. The filter unit further comprising a dedicated pump having an inlet communicating with the filtering chamber and an outlet communicating solely with the rotatable member such that operation of the pump causes filtered water from within the filtering chamber to be pumped through the rotatable member to exit the at least one outlet and impinge on the internal face of the mesh so as to cause particulates and other foreign matter located on an external face of the mesh to be dislodged.

    Abstract: A method and apparatus for filtering particulates from a turbid liquid is provided. The apparatus is preferably used to filter particulates from water used to flush a pipeline after a cleaning operation, after hydrostatic testing or during product displacement at a high flow rate. The apparatus includes an inlet valve for receiving the turbid liquid from a liquid source connected to a gas buster for discharging the turbid liquid and air into a break tank located beneath the gas buster. A self-cleaning portable liquid filter having an inlet is connected to an outlet of the break tank and includes a screen filter for receiving the turbid liquid from the break tank. Particulates from the turbid water are accumulated on an internal surface of the screen filter and clean water is discharged from the filter through a discharge port. A flush mechanism is provided to rinse the accumulated particulate cake from the surface of the screen filter upon actuation of an automatic rinse cycle. A sludge tank is located below the filter and flush mechanism for capturing a flush liquid and the particulates. A centrifugal pump driven flush line having a first end connected to the sludge tank and a second end connected to the break tank is provided for recirculating the flush liquid and accumulated particulates from the sludge tank to the break tank to be re-filtered. The turbid liquid is received from the pipeline through the inlet valve and discharged through the gas buster into the break tank. Where a plurality of break tanks are provided, the fluid levels are equalized. The turbid liquid is then pumped from the break tank to the self-cleaning portable liquid filter and a clean liquid is discharged from the outlet thereof. An automatic rinse cycle is engaged upon actuation of a signal triggered by sensing of a predetermined pressure differential across an inlet and an outlet of the screen filter.

    Abstract: A self-cleaning filter having an enclosed screen assembly, a rotatable mounted cleaning system located within the enclosed screen assembly, and a propulsion system which causes the cleaning system to rotate is disclosed. The cleaning system and the propulsion system use a frame with a fluid delivery system that is connectable to a pressurized fluid source. Fluid is delivered to propulsion apertures which generate propulsion fluid streams to provide the propulsion for the frame. Fluid also is delivered to a plurality of cleaning apertures which generate cleaning fluid streams that strike apertures in an outer cylindrical surface as the frame rotates. The cleaning fluid streams prevent clogging of the apertures in the outer cylindrical surface ensuring the filters function.
