HUBER Belt Screen EscaMax® Versatile wastewater inlet screen

  • Excellent separation efficiency due to its perforations
  • Reliable cleansing of the perforated plates with a rotating brush
  • Very compact system with minimum space requirements
  • Easy-to-retrofit into existing channels

The EscaMax® complements the well-known HUBER program for municipal and industrial wastewater screening, as it is particularly well suited in situations where excellent separation efficiency is required in deep channels with high water levels.

Perforated screening elements provide superior separation efficiency in comparison with slit screening elements. It has been determined that two-dimensional perforations are better than one-dimensional slits. Formation of screenings rolls is prevented by rake bars extending over the full width of the screen in combination with the screen‘s installation angle. Even cans and bottles are lifted by these rakes.

Each end of the filter belt of the HUBER Belt Screen EscaMax® is connected with a drive chain that is driven by chain wheels. Each chain wheel is driven by a sprocket on a common shaft and a flange mounted gear motor. When they have passed the upper turning point the screening elements are cleaned by an internal spray nozzle bar which operates against screening direction.

A separately and continuously driven roller brush enhances the cleaning process additionally. The roller brush operates against the travel direction of the filter belt, this improves cleaning efficiency significantly (see detail sketch).

Another advantage of this cleaning method is that a majority of the screenings, including abrasive material, are removed from the screening elements already in the first step of the cleaning process by the spray bar. It is obvious that the wear of both the screening elements and the roller brush is considerably reduced in this way.

The sturdy HUBER Belt Screen EscaMax® is able to reliably cope with even high amounts of gravel and grit. The two-dimensional screening elements prevent especially long fibres from passing through the screen and achieve thus the maximum separation efficiency.

The Benefits of the EscaMax® Screen

  • Excellent separation efficiency due travelling perforated plates
  • Reliable cleansing of the perforated plates with an internal spray nozzle bar and counterrotating brush
  • No scraper roller for trough edge cleaning required
  • All submerged bearings are wear-resistant ceramic bearings.
  • Compact design with a low installation height above ground level
  • Completely odour-encased screen with easy to remove covers
  • Not hindered by gravel or grit
  • Easy-to-retrofit into existing channels, installation without channel recesses possible
  • The screen consists of a self-supporting folded stainless steel profile so that it can easily be lifted out of the channel.
  • Simple and easy-to-access chain tensioning unit
  • All machine components in contact with the medium are made of stainless steel and acid treated in a pickling bath (except chains, drives, bearings). As an option, the chains and chain wheels are available in stainless steel.
