Abstract:
A continuous split-stream bypass filtration system, the system comprising:(a) a filter;(b) a first passageway (7) which provides an inlet passageway for a fluid to be conveyed to the filter or to be discharged from the system;(c) a second passageway (11) which provides a passageway for fluid discharged from the filter;(d) a third passageway (8) connected to the first passageway (7) and to the filter;(e) a fourth passageway (9) interconnecting the first (7) and second (11) passageways;(f) an orifice restriction disposed in the fourth passageway, for controlling the size of an orifice in the fourth passageway (9); and(g) a fifth passageway (12) for discharging fluid from the fourth passageway (9);whereby the fluid discharged from the second passageway (11) is split into a first stream flowing through the third passageway (8) to the filter and a second stream flowing through the fourth passageway (9) to be discharged through the fifth passageway (12), the proportion of the fluid which is routed to the filter or which is discharged through the fifth passageway (12) being controlled and determined by the size of the orifice in the fourth passageway (9).
