  • Patent number: 10780186
    Abstract: Water systems, medical equipment, and apparatus for thermal disinfection comprise a control unit which starts the disinfection of a fluid path by controlling a heating unit to heat water and controlling an actuator to enable heated water to flow into the fluid path. The control unit reads the temperature as measured by a temperature sensor during the disinfection and calculates an achieved disinfection dose. The achieved disinfection dose is compared with a set disinfection dose and the disinfection is discontinued if the achieved disinfection dose corresponds to the set disinfection dose.

  • Patent number: 10773986
    Abstract: A method of treating produced water, such as frac flowback, that includes pre-treating the produced water which is followed by a crystallization process that produces a condensate that typically includes ammonia and benzene. The ammonia and benzene concentration is reduced by biologically nitrifying and denitrifying the condensate. This produces an effluent that is directed to a solids-liquid separation process that removes suspended solids. The solids-liquid separation process produces another effluent that is subjected to a benzene polishing process that further reduces the benzene concentration of the effluent produced by the solids-liquid separation process.

  • Patent number: 10737200
    Abstract: A method of operating a filter press, wherein filter material is fed into a filter chamber so as to form a filter cake between at least two sides of a flexible said filter medium. Filtrate is received from the filter chamber and the filter cake formed the filter chamber is discharged. Prior to discharging the filter cake, compression is applied on the filter cake formed within the filter chamber by providing compression fluid gas at a compression pressure exceeding a prevailing pressure within the filter chamber, directly on a side of the filter medium exterior to the filter chamber, so as to exert said compression pressure directly on said side of the filter medium, thereby causing the filter medium to yield against the filter cake.
