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.

A fluid separation apparatus for removing one fluid component from another fluid component in a fluid stream includes an impeller disposed between an annular inlet chamber and a first fluid chamber having a hollow, conical trapezoidal shape with a diameter that reduces along a portion of the length of the first fluid chamber. The impeller redirects a liquid flowing in a circular swirling flow path along the wall of the inlet chamber to an outlet an inlet of the first fluid chamber disposed adjacent the central axis of the first fluid chamber. A coaxially aligned extraction pipe extends into a lighter density fluid envelope formed in the first fluid chamber adjacent the inlet of the first fluid chamber. The extraction pipe may be dynamically adjustable based on the shape of the lighter density fluid envelope to maximize removal of lighter density fluid from the lighter density fluid envelope.
