Muhr Fish Protection
FISH LIFTING SYSTEMS
Natural fish protection on the basis of the latest biological engineering findings.
In recent years, fish protection and fish pass facilities have become an increasingly focal development constituent of all water construction projects - irrespective of whether these constitute new construction projects or the retrofitting of existing systems.
Muhr supports you here with intelligent solutions, based on the latest biological engineering findings arising through cooperation with science and research, as well as experience gained within the framework of numerous projects.
Fish protection at water extraction plants & hydro power plants
The swimming behavior of fish is fundamentally influenced by the prevailing flow conditions at the intake screens.
Optimum fish protection starts with the correct screen design, and therefore before the first coarse cleaning stage.
As one of the first suppliers in the world, Muhr has been propagating the use of fish-friendly horizontal screens for over 25 years now. Since then this concept has been consistently further developed in conjunction with the associated screening systems.
Muhr horizontal screening systems are therefore not only particularly efficient in cleaning, they are also designed to be particularly fish-friendly.
Screen Drum Units
The results of many years of experience and competence in the construction of intelligent screen cleaning solutions:
A self-cleaning screen in the form of a screen drum unit. Exceptionally fish-friendly thanks to the perfect flow behavior, simultaneously with extremely low operating costs. Additionally, this system can be integrated into the natural environment such that it is visually highly inconspicuous in comparison to conventional screening systems, and it is biologically water neutral. Furthermore, this system can also be submersible if required.
Optimization of conventional screening systems
In the event that it is not possible to use horizontal screens, Muhr also offers fish protection technology designs for conventional screening systems. Starting with the shape and spacing of optimized screen bars and screens as a whole, as well as a fish-friendly optimum design of the cleaning rakes, right through to the special cleaning controllers, which enable the fish to exit the intake area with ease.
Fish Lifting Systems
In addition to fish protection at the intakes, Muhr also assists you in realizing suitable fish ascending and descending solutions. The Muhr fish lifting system in particular offers a whole host of advantages, also and especially when it comes to integration into existing systems: The spatial requirements of this system are minimal and it demands no additional impact on the existing natural environment. In the event of flooding, the system can be switched off at any time and subsequently simply switched back on again.
Fish protection and fish migration are not simply design tasks, they also form the basis of a great deal of research. The Muhr fish lifting system offers the ideal prerequisites here for a connected monitoring system for counting and measuring the passing fish.
