Abstract:
There is described a tray unit for a wastewater treatment device. The tray unit has a substantially frusto-conical profile defining an axis and a central aperture. The tray unit comprises a plurality of distinct tray sections arranged around the axis.

There is also described a method of assembling a tray assembly for a wastewater treatment device. The method comprises the steps of: providing a plurality of tray units, the tray units each having a substantially frusto-conical profile and a central aperture and comprising a plurality of connecting lugs each defining a hole; attaching a first one of the tray units to a plurality of support members by inserting the support members through the hole of the connecting lug of the first tray unit and securing the first tray unit to the support member; and attaching a second one of the tray units to the plurality of support members by inserting the support members through the hole of the connecting lug of the second tray unit and securing the second tray unit to the support member to form an assembly of tray units.
