Abstract
Radwaste contaminated effluent generated by an underwater source is filtered by a submersible filter system employing cannister shielded filter cartridges. The system has a submersible frame that fixedly mounts a coupling for each filter cannister. Each cannister is internally fitted with a filter cartridge and mounting means configured to divide the cannister to an inlet chamber and a filtrate chamber, the latter having outlet ports for exhausting the filtrate to the pool in which the system is submerged. The inlet chamber is in check valved fluid communication with an external nipple of the cannister detachably connected to a coupling of the frame through which the radwaste effluent is received. One end of an elongate tool and an upper end of the cannister have interconnectable cooperating means for remotely removing and replacing cannisters on the frame. The check valved inlet chamber prevents escape of radwaste from the filter inlet chamber during and after removal of a cannister from the frame.
