Water retention barrier
A fuel water separator comprises a housing that defines an internal volume that receives a mixture. The fuel water separator further comprises a filter element that is positioned within the internal volume. The filter element comprises a first endplate and a second endplate that is located opposite the first endplate. The filter element further comprises a filter media that is coupled to the first endplate and the second endplate. The filter media is structured to separate a dispersed phase from a continuous phase of the mixture. The filter element further comprises a collection sump that is located below the first and second endplate and structured to receive the dispersed phase. The filter element further comprises a retention barrier disposed above the collection sump. The retention barrier comprises a drain opening structured to discharge the dispersed phase through the retention barrier into the collection sump.
1. A fuel water separator comprising:
a housing defining an internal volume, the internal volume receiving a mixture; and
a filter element positioned within the internal volume, the filter element comprising:
a first endplate;
a second endplate located opposite the first endplate; and
a filter media coupled to the first endplate and the second endplate, the filter media structured to separate a dispersed phase from a continuous phase of the mixture;
a collection sump located below the first and second endplate, the collection sump structured to receive the dispersed phase; and
a retention barrier disposed above the collection sump, the retention barrier comprising at least one drain opening, the at least one drain opening comprising a first crescent-shaped drain opening.
2. The fuel water separator of claim 1 , wherein the at least one drain opening further comprises a second crescent-shaped drain opening positioned substantially opposite the first crescent-shaped drain opening relative to a center of the retention barrier.
3. The fuel water separator of claim 1 , wherein the first endplate comprises a flow passage; and
wherein the retention barrier is coupled to the first endplate within the flow passage.
4. The fuel water separator of claim 1 , wherein the first crescent-shaped drain opening has a diameter of between 5.6 millimeters and 9.53 millimeters.
5. A fuel water separator comprising:
a housing defining an internal volume, the internal volume receiving a mixture; and
a filter element positioned within the internal volume, the filter element comprising:
a first endplate;
a second endplate located opposite the first endplate; and
a filter media coupled to the first endplate and the second endplate, the filter media structured to separate a dispersed phase from a continuous phase of the mixture;
a collection sump located below the first and second endplate, the collection sump structured to receive the dispersed phase; and
a retention barrier disposed above the collection sump, the retention barrier comprising:
a retention bowl having an angled surface, and
a porous, hydrophilic material on the angled surface, the porous, hydrophilic material promoting collection and drainage of the dispersed phase.
6. The fuel water separator of claim 5 , wherein the porous, hydrophilic material is disposed on a bottom surface of the water retention barrier such that the porous, hydrophilic material contacts the collection sump.
7. The fuel water separator of claim 5 , wherein the retention barrier further comprises a plurality of hydrophilic fibers disposed across an inner diameter of the first endplate.
8. A fuel water separator comprising:
a housing defining an internal volume, the internal volume receiving a mixture; and
a filter element positioned within the internal volume, the filter element comprising:
a first endplate;
a second endplate located opposite the first endplate; and
a filter media coupled to the first endplate and the second endplate, the filter media structured to separate a dispersed phase from a continuous phase of the mixture;
a collection sump located below the first and second endplate, the collection sump structured to receive the dispersed phase; and
a retention barrier disposed above the collection sump, the retention barrier comprising:
a retention bowl; and
a drain opening, the drain opening positioned at a central region of the retention bowl and facing a radial direction, such that the drain opening drains the dispersed phase in the radial direction.
9. The fuel water separator of claim 8 , wherein the retention bowl further comprises an angled surface slanted downward towards the central region of the retention bowl, the angled surface facilitating movement of the dispersed phase toward the central region and through the drain opening.
