A filtration apparatus and methods of installing, using, and retracting the same. A filtration apparatus includes a compression gland, a ball valve, and a filter pipe. A distal portion of the filter pipe has one or more filtration holes. The filtration apparatus may be installed in a process pipe and the distal portion of the filter pipe may be disposed within the process pipe. The filter pipe can be easily retracted from the process pipe without interruption of the industrial process. The filtration apparatus can be automatically cleaned by compressed air or water.
