A porous tube or conduit formed in a series of loops coiled around a center line, the series of loops having a first loop, the first loop having a first extension configured with a first open end in fluid communication with the first loop, the series of loops having an end loop, the end loop having a second extension configured with a second open end in fluid communication with the end loop, wherein the first open end and the second open end are positioned proximate the center line and the first loop, and, thus, functions to provide a more efficient filter having less plugging or clogging of the filtration membrane, reduced the need for self-cleaning of the porous tube, minimize the effects of pressure drop across a porous tube, installed inside a tank, accommodating shipping, handling, and storage, simplified system arrangement, thereby provide a more efficient filtration device, system, process.
