Abstract: Processes and apparatuses for converting PFAS. PFAS are heated and introduced to a reactant which will convert the PFAS. The PFAS may be in a stream that is a PFAS enriched stream formed by desorbing the PFAS from an adsorbent which removed the PFAS from a contaminant stream. An effluent from the PFAS conversion reaction is treated in a treatment zone and a treated effluent may be released to the atmosphere.

Abstract: A method of using an endoscopic system includes generating, by a light system, electromagnetic waves, the light system including a source of imaging light and a separate source of heating light; directing the electromagnetic waves from the light system to a window at a distal end of an endoscope; determining if the window of the endoscope is configured to allow a first portion of the electromagnetic waves to pass therethrough while absorbing a second portion of the electromagnetic waves in order to heat the window; allowing or not allowing activation of the source of heating light depending on if the window of the endoscope is determined to be configured to allow the first portion of the electromagnetic waves to pass therethrough while absorbing the second portion of the electromagnetic waves.

Abstract: A pail separation device comprised of two halves, each half having a wedge at the end of an exterior brace, an interior brace having a curved face, and which is attached to the exterior brace, and a handle attached to the interior brace and to the exterior brace. Also included is a fastener for locking the two halves together. The two halves further include ridged surfaces that mesh together to reduce slipping. The first and second wedges are dimensioned to fit between pails in a stack of pails such that force applied to the first and second handles can push the first wedge and the second wedge between the pails of a stack of pails so as to separate those pails.
