  • Patent number: 12146302
    Abstract: This specification describes systems for the treatment and reuse of grey water and related processes. An exemplary system collects grey water from baths and showers and treats it for use in toilet flushing. Influent bathing water passes through a prefilter to remove larger particles and flows into a grey water collection tank. Collected grey water is filtered through a membrane designed to remove suspended solids. Membrane permeate passes through a sorbent media to remove soluble organics and then flows into a permeate tank. A chemical agent is used to disinfect water in one or more parts of the system and optionally to clean the membranes. A control system manages the operation of system. The system operates in a generally daily cycle with permeation dispersed over a material time, for example 4 or 8 hours or more.

According to the invention, the control unit is associated with logical means having a first threshold value defining means that are designed to determine at least one first threshold value (YGrenzmax, YGrenzmin) depending on the first actual operating parameter (X) and/or at least one further actual operating parameter (XH, YH, YHH) that could lead to a failure state of the positive displacement pump when exceeded or fallen short of.

  • Patent number: 9849412
    Abstract: A method of detecting clogging of a fluid filter is disclosed. The method includes measuring, at successive sampling instants, the pressure difference ?P from upstream to downstream across the filter, calculating the first time derivative {?P}? of the pressure difference ?P at different instants, and then sending a clogging signal SC representative of the filter being clogged when the first derivative {?P}? is equal to zero.

  • Patent number: 9752950
    Abstract: A device comprising a pressure monitor and a control means that receives a signal representing measured pressure at the pressure monitor and controls the controllable elements of a fluid system is utilized to monitor a fluid system for error conditions, to optimize operations and to diagnose the fluid system. By following a testing protocol that selectively enables parts of the system, the control means narrows the list of possible failing components. Comparing the measured pressure against normal pressures allows the device to identify error conditions. Determining the volume of fluid being transported and controlling the duration of the flow optimizes operation of the fluid system.

  • Patent number: 9345826
    Abstract: A fluid filtration system comprising a cross-flow filter is arranged to permit a first pump to recirculate part of the retentate of the filter to the inlet of the cross-flow filter and a second pump to return part of the permeate to the inlet of the cross-flow filter. A third pump is configured supply source fluid to the inlet of the filter. The flow path between the second pump and the cross-flow filter inlet may include an adsorption filter that may selectively remove contaminants, toxins, or pathogens in the permeate. A controller may control the first, second and third pumps to provide predetermined flow ratios among the fluid flow paths of the system in order to achieve a desired filtration level. This system may be applicable to the removal of harmful substances from blood, by first separating the plasma from the blood and then removing harmful substances from the plasma.

  • Patent number: 9162025
    Abstract: Disclosed is a therapeutic fluid reservoir to be used with an ambulatory portable infusion device. The reservoir includes a pliable shell defining a varying inner volume that varies based on the volume of therapeutic fluid held inside the reservoir, the varying inner volume having a predetermined maximum volume for containing a corresponding volume of therapeutic fluid and an outlet port for communicating fluid from the reservoir to a patient, the varying inner volume decreasing upon therapeutic fluid being communicated through the outlet port. Upon the reservoir reaching the predetermined maximum volume when being filled with therapeutic fluid, any therapeutic fluid in excess of the predetermined maximum volume driven into the reservoir causes a substantially corresponding amount of therapeutic fluid to exit out of the reservoir via the outlet port and/or at least one other port provided in the pliable shell.
