Abstract:
A method for removing particulate matter from a liquid medium comprising the steps of:A. providing a device for capturing and removing particulate matter from a liquid medium comprising; 1) a hollow tubular member having a first end and a second end; 2) an agitator disposed in said hollow tubular member and configured to generate circulation of the liquid with the particulate matter disposed therein; 3) fluid return openings in said hollow tubular member to allow fluid to enter into the tubular member; 4) a particulate capturing member slidably mounted on said hollow tubular member and movable from a particulate retaining position to particulate discharging position; 5) a mechanism for engaging and moving said device into and out of said liquid; B. inserting said device in said liquid having the particulate matter, with the particulate matter collector in the particle collecting position; C. causing the agitator to circulate the liquid having the particulate matter therein to circulate and collect a portion of the particulate matter in the particulate matter collector during said circulation; D. ceasing the circulation; E. removing the device from the liquid with the particulate matter in said particulate matter collector to a discharge position; and F. moving the particulate matter collector to the particle discharge position.
