Abstract

Land is put into the waste water circuit. Then it is removed into a hopper and is returned to the ejector device. At its outlet it has a shutting-off device. The heat exchanger has waste water circuit into which sand is introduced. It is separated off into the bin. The ejector is inserted into the waste water circuit. The outlet of the ejector device has a valve. (Provisional Basic previously advised in Week 8406).
