Abstract (en)
[origin: WO2017129247A1] In order to improve a process water preparation system for preparing process water in a process water circuit of a cleaning installation, in particular a carwash – wherein, in the process water circuit, dirty process water from the cleaning installation is collected and cleaned, oxygen is supplied to the cleaned process water and the cleaned and oxygen-enriched process water is stored in order to be returned to the cleaning installation when required, the process water preparation system having a measuring device for measuring the oxygen content in the process water in order that oxygen can be supplied to the cleaned process water depending on the measured oxygen content – so as to minimize noise during operation of the cleaning installation, it is proposed that the measuring device is designed to measure an actual value of the oxygen content in the cleaned and oxygen-enriched process water after enrichment with oxygen. Also proposed are an improved cleaning installation and an improved method for preparing process water in a process water circuit of the cleaning installation.
