Abstract: A multiple-stage process for the collection and treatment of biological waste, and for rendering the biological waste biologically inactive for the safe and economical environmentally non-contaminating disposal thereof. Moreover, also disclosed is an arrangement for the collection and treatment of biological waste utilizing the inventive process, and is especially adapted for the collection and treatment of biological waste which is generated during a surgical or medical procedure implemented on a patient or during an autopsy.
Abstract: A method and apparatus for separating a volatile solvent from a solution of the solvent and a relatively non-volatile solute. A temperature gradient is provided across solvent-absorbing and gas-entraining matrix material infiltrated with the solution, resulting in concentration of the solution near the hotter matrix surface and dilution of the solution near the cooler matrix surface. The process lends itself to the desalination of sea water and to applications which require the recovery of either solute or solvent.
