Abstract: An assembly and a method for treating raw water wherein the raw water is heated on the heating side of a heat pump and at least partially evaporated into an air stream. At least part of the raw water evaporated into the air stream is separated in a suitable device. In addition, the heat pump is provided with heat on the cooling side by means of heated raw water that has not been evaporated into the air stream, and the heat pump has a thermal coupling in a coldest section of its cooling side, in order to provide cooling for external applications.

Abstract: A device for the contact of a gas phase with a liquid medium, and a method for operating the device. The liquid medium here is directed into the device and some of it is raised by means of a conveying device. The liquid medium raised is distributed over a rotating brush by way of a distributing means. At least one gas inlet and a fan here generate a gas stream from a lower portion of the device to an upper portion of the device. The liquid medium distributed over the upper surface of the brush is directed back by way of the brush, counter to the gas stream, into the lower region.

Abstract: Process for the filling of the interior space of insulating glass units whereby the air-filling is replaced by a heavier gas. An optimum is set between an as-short-as-possible filling time and as-small-as-possible turbulent mixing losses through the appropriate control of the filling and evacuation rate.
