Abstract: An electroflotation apparatus for removing impurities from waste water is disclosed. The apparatus comprises an electrolytic cell for treating the waste water and generating a flock containing the impurities as well as an outlet pipe having a linear central axis located co-axially with the electrolytic cell for passing the water and flock from the electrolytic cell to a separation area. The outlet pipe comprises a first end connected to the electrolytic cell and having a first diameter, as well as a second end through which the treated water and flock exit the outlet pipe, the second end having a second diameter. A length extends between the first diameter and the second diameter. The ratio of the second diameter to the first diameter is between 1.5:1 and 6:1. The ratio of the length to the first diameter is between 7:1 and 45:1. The outlet pipe reduces the turbulence of the treated water from the electrolytic cell before the treated water is passed to the separation area such that aggregation of the flock in the separation area is increased.
