Ecological hydro power:
Fish friendly turbine
Due to the characteristic design and operation of a DIVE-Turbine it is possible to realize a very
fish friendly hydro power plant. The DIVE-Turbine is of no danger to animals that enter the turbine
chamber through the intake rake.
Therefore the DIVE-Turbine is a convincing argument in the authorization procedure.
Fix runner blades: small gaps – little risk of injury + No gaps between runner blades and hub.
+ Minimal gaps between runner blades and turbine vessel. The gaps are too tiny to be a risk
for the fish.
Minimal number of runner blades – little probability of collision + Minimal number of runner blades (3, 4 or max. 5 runner blades). It is possible to realize a
very fish friendly design of the DIVE-Turbine with only 3 runner blades.
Operation with variable speed – low collision speed and shear forces + To optimize the efficiency the rotational speed of the DIVE-Turbine is reduced in part load
operation. This means that shear forces between runner and turbine vessel remain
constantly low.
+ Therefore also the collision speed remains low because many days of the year the DIVE-
Turbine is running with significantly lower runner speed. Because of the fixed blades, the
distance between runner blades remains constantly open.
Comparison of fish friendliness of DIVE-Turbine and Kaplan turbine: Only those fish are taken into consideration, which accidentally enter the turbine chamber through the intake rake. The total mortality of the whole power plant is significantly lower, because all larger fish and all fish that take a different passage around the turbine can surpass the power plant without any damage. See for example the mortality of a power plant with a guidance-rake system and downstream migration bypass, where 80% of downstream migrating fish use the bypass-passage for downstream migration.
DIVE Turbinen GmbH & Co. KG offers support in the authorization procedure by developing a site-specific fish friendly power plant design and calculating the individual mortality rate.

Ecological hydro power:
Fish friendly rake and guidance systems
A fish friendly power plant layout makes sure that fish and other animals are able to migrate
upstream and downstream.
Upstream migration There are well-proven concepts for upstream migration of organisms (e.g. fish pass).
Downstream migration
a) Inclined vertical rake with guidance and downstream migration system
b) Horizontal rake (horizontal bars) with guidance and downstream migration system
c) Shaft power plant with plain horizontal rake and migration openings
guidance wall at the bottom of the rake
for tracking the migration openings
flap gate for flushing with openings
for downstream migration
