Oval wastewater treatment plants - VFL®

Wastewater treatment plants with oval ground plan from AT30oval to AT225oval (standard transport with sea container or regular truck)

The compact, “one-tank system” wastewater treatment plants from AT30oval to AT225oval are comprised of a single vertical tank with oval ground plan, 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 small wastewater treatment plants from AT30oval to AT225oval is designed for decentralized and semi-centralized solutions of wastewater treatment in the range of 4,5 up to 33,8 cubic meters per day (30PE-225PE).

The small wastewater treatment systems comprised of the biological reactors from AT30oval to AT225oval can be gradually expanded up to the capacity of 135 cubic meters per day (900PE) by installing several units in parallel.
