Reliable screens for any application

Innovative technology from one source

The HUBER screening program comprises a wide variety of screen systems and enables us to offer the perfect solution for any installation conditions, flow rates and bar spacings

Mechanical treatment is indispensable as the first process step of preliminary treatment of wastewater, both for STP inlets and other fields of application, such as process water treatment.

Disturbing coarse material has to be removed in order to protect the subsequent steps against damage/pollution or to relieve them. It is the goal to completely separate floating, settling and suspended material, depending on the bar spacing, and remove the material prior to discharging it into a container.

The hygienic conditions, operation safety and the fact that there are nearly any maintenance works are factors becoming more and more important.

For municipal STPs an additional screenings washing is recommendable as regards the denitrification, in order to lead the soluble organics again to biological treatment.

FAQ

Frequently Asked Questions

The size of the opening width on the one hand and the shape of the screening element on the other.

With one-dimensional screening elements such as bars, the separation efficiency is generally lower than with two-dimensional elements such as perforated plates, mesh, etc. This is mainly due to the fact that it is very difficult for long-fibre material such as hair to pass through a perforated plate.

This requirement can only be met by a screen that covers the full range of screen opening widths from fine to coarse screens.

In addition, the screen bars must be designed with the respective geometry to meet the corresponding requirement.

A typical screen that fulfills all these requirements is our HUBER Multi-Rake Bar Screen RakeMax®

Machines with a steep installation angle are best suited for such applications.

This screen installation option allows the installation space to be very compact, especially in the direction of flow.

Typical examples are our HUBER Multi-Rake Bar Screens RakeMax® and RakeMax® CF as well as the HUBER Belt Screen EscaMax®, HUBER Coarse Screen TrashMax® and HUBER Grab Screen TrashLift.
