  • Patent number: 11453608
    Abstract: Sludge, for example primary sludge or waste activated sludge or both from a wastewater treatment plant, is pre-treated prior to anaerobic digestion. The pre-treatment includes an optional mechanical treatment to reduce the viscosity of the sludge and a biological hydrolysis treatment. The biological hydrolysis treatment may be performed in a series of reactors some of which are maintained at a temperature in the range of 50 to 70° C. The reactors provide a combined residence time in the range of 0.5 to 6 days. Optionally, measurements of the pH of the sludge during or after biological hydrolysis, or the production of biogas from a downstream anaerobic digester, may be considered in adjusting the temperature of one or more of the biological hydrolysis reactors.

  • Patent number: 11452954
    Abstract: A method for determining an airflow volume through an air filter is presented. A negative pressure is created within a system housing of an air handling system. Particulate matter is filtered on a filter media of an air filter. A displaceable baffle is progressively moved baffle in proportion to an accumulation of particulate matter on the filter media, wherein the displaceable baffle is movably mounted within a bypass conduit of an airflow sensor device. An output voltage is identified from a magnetic field sensor, wherein the output voltage is proportional to a magnetic flux density of a magnetic field from an actuation magnet mounted on the displaceable baffle. A position of the displaceable baffle is determined based on the output voltage generated by the magnetic field sensor. An accumulation of particulate matter on the filter media is determined based on the position of the displaceable baffle.

  • Patent number: 11439925
    Abstract: An apparatus for extraction and recovery of components from biomass feedstocks with pressurized low polarity water. The apparatus is configured with four or more reaction columns, wherein each column is in separate communication with a supply of hot water, a first supply of pressurized heated water, a second supply of pressurized heated water, and a supply of pressurized cooling water. Components may be extracted concurrently from two or more batches of the biomass by, first placing the two batches of biomass into two selected columns, separately flooding the two columns with pressurized water, heating the columns and their contents to the point where the water becomes pressurized low polarity (PLP) water, recovering the PLP water comprising the extracted components from the two selected columns, cooling the columns with PLP water, and removing the spent biomass material from the columns.

  • Patent number: 11434464
    Abstract: The disclosure provides a filtration system for a cell culture apparatus and a method of cell culture. The filtration system comprises a bioreactor vessel and two or more alternating tangential flow (ATF) filters connected in parallel. A failure in either filter is detected by an in-line sensor, and an automated response system functions to sequester the malfunctioning filter by stopping the flow of liquid media through the filter. Media flow through the remaining operable filters can be increased so that the rate of perfusion through the bioreactor remains relatively unchanged. Such a system may prevent issues that arise from ATF filter failures in conventional perfusion bioreactors, thereby improving the long-term viability of cell cultures.

  • Patent number: 11427484
    Abstract: A salt water chlorinator assembly along a closed loop water circuit incorporates a chlorinator cell subassembly and a flow switch subassembly into respective fluidly connected chlorinator assembly housing interior portions. The chlorinator cell subassembly includes an electrolysis cell controlled by a chlorinator printed circuit board. The flow switch subassembly includes a flow sensor mounted upon a printed circuit board assembly (PCBA). A flow switch cable selectively attaches to a PCBA connector. Water flow rate data generated by the flow switch sensor, communicated via an external controller to a smart circulation pump, is used to enable automatic adjustment of the pump speed based upon the flow rate data. The external controller may further alert an end user of undesirable flow rate deviations due to a condition (e.g. a clogged pump/skimmer basket and/or dirty filter) along the closed loop circuit requiring attention.
