Abstract

Water purification plant for purifying wastewater within a container having an inlet (2) and an outlet (8), is provided with a biological purification mechanism (7) that is surrounded by a mechanical purification mechanism (4, 5). The biological purification mechanism includes an upper filter bed and a lower filter bed with an intermediate air gap and an air gap below the lower filter bed. An Independent claim is also included for a cassette for use in a water purification plant, comprising filter bed(s), an intermediate air gap, a lower filter bed, and a distance mechanism for creating a lower air gap, separating the lower level of the filter from the water level at the bottom of the biological purification.
