Research output: Contribution to journalJournal articleResearchpeer-review


The composition of grey wastewater depends on sources and installations from where the water is drawn, e.g. kitchen, bathroom or laundry. The chemical compounds present originate from household chemicals, cooking, washing and the piping. In general grey wastewater contains lower levels of organic matter and nutrients compared to ordinary wastewater, since urine, faeces and toilet paper are not included. The levels of heavy metals are however in the same concentration range. The information regarding the content of xenobiotic organic compounds (XOCs) is limited. From this study, 900 different XOCs were identified as potentially present in grey wastewater by the use of tables of contents of household chemical products. 2002 Elsevier Science Ltd.
