Patent number: 11660382Abstract: An improved valve leak detection system. The improved valve leak detection system comprises a membrane pump defining a flow path arranged to be opened and closed by at least one valve, a measuring device, a comparator, and a signal generator. The measuring device is configured to determine a conductivity value between two points on the flow path of the membrane pump, one point arranged upstream of the at least one valve and the other point arranged downstream of the at least one valve. The measuring device measures the conductivity value when the at least one valve is closed. The comparator is configured to continuously monitor the conductivity value. The signal generator is arranged to provide an output signal when the conductivity value is indicative of a valve leak condition for a set number of measurements within a set period of time.Type: GrantFiled: December 13, 2017Date of Patent: May 30, 2023Assignee: Quanta Dialysis Technologies LimitedInventor: Eric William Westenbrink

Patent number: 11638903Abstract: Enhanced cleaning of a fouled membrane is achieved via controlled deformation in a method wherein a feed composition, comprising a solvent and dissolved components, flows into a retentate side of a membrane module. The solvent passes through the membrane from the retentate side to a permeate or draw side of the membrane module while retaining the dissolved components on the membrane. As a foulant accumulates on either side of the membrane, a driving force is generated across the membrane, wherein the membrane responds cyclically by deforming back and forth toward the permeate or draw side and toward the retentate side. The foulant is dislodged from the membrane via mechanical fatigue at the foulant-membrane interface caused by the deformation of the membrane and contact with a spacer in contact with the membrane.Type: GrantFiled: October 12, 2020Date of Patent: May 2, 2023Assignee: Massachusetts Institute of TechnologyInventors: Omar Labban, Grace Goon, John H.
