PRINCIPLE

Electrified barriers create in water repellent electric fields thank to pulse generator.

When the fish swim up against the stream of water, electrified barriers have a very good efficiency.

When the fish swim with the stream of water, the barrier should be used as a screen deflection or guidance system. The fish must find a way out nearest the barrier.

Moreover, the hydraulic conditions are an important factor in the efficiency.

DIFFEENT MODELS

The generator unit delivers pulses with a frequency, a width and amplitude defines according to the characteristics of the place. (see preliminary study paragraph).

Upstream barrier with two electrodes. It is a barrier system with vertical bars, which prevents the fish from swimming upstream to take a channel.

Upstream barriers for fishes

Three or two horizontal electrodes barrier made for downstream guidance in shallow water. The voltage gradient generated by the electrodes forces the fish swimming in the stream direction to move toward the tailrace.

PRELIMINARY STUDY

To identify problems of efficiency and safety, it is necessary to carry out a preliminary study with a site plan. You also have to specify the following:
