Abstract
A gas and liquid mixture separation and collection system for zero gravity operation that can be applied to a urinal toilet is disclosed. There is an inlet to receive the gas and liquid mixture. The mixture is directed to a filter having an air side. A vacuum pump on the air side of the filter generates a pressure delta to force the inlet flow. A peristaltic pump is used to transfer liquid away from the filter surface. In doing so, the flow on the liquid side of the membrane filter may contain some gas left over from the inlet flow mixture, but there is substantially less gas than in the gas and liquid mixture at the inlet. The filtered mixture is directed to an expandable collection bag that is attached to the air side of the filter so the filter process can be repeated to remove more gas from the mixture.
