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 sec…
