Abstract
Embodiments of the invention provide venting and filtration systems with a membrane that is permeable to gas and substantially impermeable liquid. The systems can remove a gas from a liquid entrained with gas. The systems can include a reservoir in fluid communication with the membrane and a liquid outlet. The membrane can help prevent the gas from reaching the liquid outlet.
Claims17
A passive filtration system that filters liquids entrained with gas, the liquids including one of liquid food product and drinking water, the filtration system comprising:
- a housing including a reservoir;
- a filter positioned in the reservoir, the filter dividing the reservoir into an upstream chamber and a downstream chamber;
- and
- a non-porous membrane in fluid communication with the upstream chamber, the non-porous membrane being permeable to gas in order to vent gas from the one of liquid food product and drinking water in the reservoir.
A filtration system that filters liquids from one of liquid food product and drinking water entrained with gas, the filtration system comprising:
- a housing including a reservoir;
- a filter positioned in the reservoir, the filter dividing the reservoir into an upstream chamber and a downstream chamber;
- and
- a membrane in fluid communication with the upstream chamber and the downstream chamber in the reservoir, the membrane permeable to the gas in order to allow the gas to flow from the upstream chamber to at least one of the downstream chamber and out of the housing in combination with at least a portion of the one of liquid food product and drinking water.
