Residential wastewater treatment plants - VFL® from AT6 to AT20

The compact, “one-tank system” wastewater treatment plants from AT6 to AT20 are comprised of a single vertical cylindrical tank, made from polypropylene - the biological reactor. The dimensions of the plants are ideally suited for transporting in a standard shipping sea container or by a regular truck.

The range of residential wastewater treatment plants from AT6 to AT20 is designed for decentralized solutions of wastewater treatment in the range of 0.6 up to 2.7 cubic meters per day (4PE-18PE).
