The FishFlow eelladder is a fishladder that is specialised in providing migration opportunities to eel. The eelladder can be used to restore eel migration in areas where migration of other fish species is not ...

In the Netherlands alone more than 3000 pumping stations contribute to the watermanagement. For fish, pumping stations present migration barriers that obstruct the natural connections between adjacent water bodies. The FishFlow fishway for pumping stations consists of a by-pass system that guides fish around the potentially lethal ...

Screw pumps are utilised to draining low laying areas, such as the polders of Northwest Europe. A screw pump consists of a long worm wheel that is placed in a diagonal pipe or through, and creates upward displacement of water when driven. These pumps, also called Archimedian screws, have been in use for many centuries as applications are found in irrigation and draining ...

Large quantities of surface waters are drawn for cooling systems by power plants and production of drinking water by waterworks. Fishes that are present in the water are drawn into the water intakes as well. Entry of fishes can result in clogging up of cleaning filters, which requires higher cleaning frequency. Passage of the filters by fishes can result in severe damage to the fishes in the ...

The fish-friendly low pressure water turbine of Pentair Fairbanks Nijhuis / FishFlow Innovations has been tested successfully on its fish-friendliness early August. For the performance of the test a scale model of the turbine (with a propeller diameter of 800 mm) was used and installed at the pumping station Leeghwater Buitenkaag* in the Netherlands. With the application of fish-friendly turbines ...

Many industrial facilities extract water from lakes, rivers or coastal waters for cooling installations, hydropower or water supply. The entrainment of floating debris or fish can have adverse effects on industrial processes and cause fish mortality. The innovative rotary drum screen that has been developed by FishFlow Innovations effectively separates solid objects from the intake water. The ...

The FishFlow siphon fish ladder is based on the principle of a poorly functioning siphon; i.e. a siphon with an air bubble. This bubble is an essential element of the construction because the volume of the bubble defines the flowrate through the system. The siphon fish ladder is equipped with a vacuum pump that controls the volume of the air bubble to prevent change of flowrate due to import or ...

Axial pumps are the most commonly applied type of pump in the Dutch pumping stations. These pumps are used in a wide variety of pumping stations, from small pumps in ditches to the pum-ping station at IJmuiden, the largest pumping station of Europe. Although frequently applied, axial pumps are amongst the most dangerous pumps for migrating fishes, Especially small axial pumps are known to have ...

The FishFlow screw pump annex hydroturbine is a special version of the fishfriendly screw pump that can not only be used to pump water, but that can also function as a fishfriendly turbine to generate electricity. To function as a turbine the Archimedean screw is lowered until the waterlevel upstream of the screw is higher than the upper end of the screw. Consequently water flows into the screw ...
