"Which screens are particularly suitable for deep channels?"

"Machines with a steep installation angle are best suited for such applications.\r\nThis screen installation option allows the installation space to be very compact, especially in the direction of flow.\r\nTypical examples are our HUBER Multi-Rake Bar Screens RakeMax\u00ae and RakeMax\u00ae CF as well as the HUBER Belt Screen EscaMax\u00ae, HUBER Coarse Screen TrashMax\u00ae and HUBER Grab Screen TrashLift."

Screens and Fine Screens

Q: "What influences the separation efficiency of screens?"

"The size of the opening width on the one hand and the shape of the screening element on the other.\r\nWith 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."

Q: "Which screen type can be used as both a coarse screen and a fine screen?"

"This requirement can only be met by a screen that covers the full range of screen opening widths from fine to coarse screens.\r\nIn addition, the screen bars must be designed with the respective geometry to meet the corresponding requirement.\r\nA typical screen that fulfills all these requirements is our HUBER Multi-Rake Bar Screen RakeMax\u00ae"

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, bar spacings and mesh sizes.

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.

Coarse material has to be removed in order to protect the subsequent treatment steps against damage/pollution. 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.

The requirement for safe operation and low maintenance is becoming increasingly important.

For municipal STPs additional screenings washing is utilised to enhance downstream biological treatment.

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.
