Abstract: A method and apparatus for removing solid matter from fluid systems which does not require system shutdown and minimizes the loss of system fluids. The invention first isolates the solid matter collection reservoir from the fluid system and then purges the reservoir for external disposal or recovery of the solid matter. The purging sequence is enhanced through the use of a venting system which prevents pressure differential buildup and also prevents the introduction of air into the separation device during the purging sequence. The entire process can be controlled manually or automatically through a control system.
