摘要： The present invention relates to a device and a process for purification of grey water. In particular the invention relates to in-home purification of grey water generated from laundry wash and/or rinse liquor for water saving by re-use. Surprisingly it has been found that it is possible to design a device and a process where, by continuous aeration, foam breaking and separation, the laundry wash and rinse water can be made substantially free of surfactants. This water is then preferably filtered to recover fresh water which can be reused for multiple applications.
