The operation of a water filtration plant is a highly demanding responsibility.
For a plant manager, broken plastic nozzles are a terrible situation, as filtration media can leak into the filtered water, forcing him to stop the process and fix the broken nozzles.
What if ANDRITZ could solve this issue with a one-time purchase that increases flow rate and delivers perfect filtration results?
The ANDRITZ Underdrain System (AUS) is the solution for new water filtration plants as well as a perfect replacement for existing nozzle filtration plants.
The AUS offers a reliable filtration process without the risk of breaking nozzles and therefore water contamination.
Watch the video to check out how it works and what advantages the AUS can offer you.
The AUS is made of 100% stainless steel. In comparison to plastic nozzles, breaking under normal process conditions is impossible. The v-shaped wedge wire bars prevent plugging and ensure a reliable, continous and maintenance free process - guaranteed.

In comparison to other underdrain systems that use cheaper, segmented distribution plates, the AUS exclusively uses a folded distribution plate without gaps between the segments. This ensure even distribution and steady flow rates, also in important backwash phases.

In case of plugging, the ANDRITZ underdrain system is designed to ensure efficient backwash phases. In combination with a backwash system, air, water, or both evenly flow through the folded distribution plate and the filtration surface. Debris and media above the AUS is flushed to the top and the efficiency of the AUS is restored to the maximum.
