Abstract
An interconnector 22 for filtration modules 18 which have axially extending tubes 90. The interconnector 22 is a rigid tubular member having conical tapered portion 88 at opposite ends to join fluid tight connections with the filtration modules.
Claims8
A removal interconnector for joining filtration modules which have axially extending tubes,
- said interconnector comprising a rigid tubular member having conical externally tapered portions at opposite ends to form fluid tight connections with the inner diameters of the tubes of two adjacent filtration modules when the interconnector is inserted into the tubes,
- the open ends of the tubular interconnector being chamfered internally and forming an acute angle and a linear anular intersection with the inner diameters of the filtrate tubes to permit an unrestricted flow of fluid between two adjacent filtration modules.
A filtration apparatus comprising:
- a pressure vessel,
- a plurality of spiral wound filtration modules serially arranged within the vessel,
- each module including a filtration membrane wound around a filtrate collection tube having conical internally tapered portions at each end,
- retaining means secured to each collection tube and engageable with the filtration membrane, and
- means for removably connecting adjacent filtration modules comprising,
- an interconnector comprising a rigid tubular member having conical externally tapered portions at opposite ends to form fluid tight connections with the conical internally tapered portions of the tubes of two adjacent filtration modules when the interconnector is inserted into the tubes,
- the open ends of the tubular interconnector being chamfered internally and forming an acute angle and a linear anular intersection with the internally tapered portions of the filtrate tubes to permit an unrestricted flow of fluid between two adjacent filtration modules.
