  • Patent number: 11440825
    Abstract: A waste treatment process utilizes a two-stage digestion process with a thermophilic digester, a heat exchanger, and a mesophilic digester. The pH of the thermophilic digestate is increased by removal of carbon dioxide with an air stripper, or by adding a pH increasing reagent upstream of the heat exchanger. The pH adjustment of the digestate protects the heat exchanger and downstream equipment and processes from struvite formation. A struvite reactor may be located in various locations downstream of the heat exchanger to produce a treated digestate or effluent that contains struvite, which can optionally be recovered for beneficial use.

  • Patent number: 11434149
    Abstract: The devices, systems, and methods of the present disclosure are generally directed to using an increase in gas pressure (e.g., through an increase in heat) to move an actuator that at least partially defines a volume containing a feed fluid in fluid communication with a membrane. As the increase in gas pressure moves the actuator, pressure on the feed fluid in the volume may increase beyond a threshold pressure sufficient to move the feed fluid through the membrane. Movement of the feed fluid through the membrane may reduce a volumetric concentration of one or more components of the feed fluid to form a permeate. For example, the increase in pressure may drive the actuator to increase pressure on salt-water in the volume and, ultimately, move the salt-water through the membrane to form the permeate as part of a reverse osmosis process achieved without the use of a mechanical pump.

  • Patent number: 11433401
    Abstract: A purification system and method may include a container receiving portion, pump, and magnetic field generating element. The container receiving portion may be configured to receive and support a container containing a mixture. Magnetic beads may be added to the container for separating a target substance from a remainder of the mixture. The magnetic field generating element may be movable relative to the container receiving portion between a non-working position remote from the container receiving portion and a working position adjacent an outer periphery of the container receiving portion. In the working position, the magnetic field generating element may attract the magnetic beads and hold them firmly against an interior surface of the container. While the magnetic beads are immobilized by the magnetic field generating element, the pump may remove the mixture from the container, leaving behind the magnetic beads bound tightly but reversibly to the target substance.
