Fish kills, caused by water intake screening impingement or entrainment through water intakes, amount to tens or even hundreds of millions of fish per annum. While legislation is applicable in some countries, others operate Codes of Best Practice or do nothing at all to protect marine habitats.

Whether legislation exists or not the benefit of installing fish protection systems can avoid the risk of plant shut down due to migrating smolt or sprats, for example, being drawn into water intakes causing damage or blockage to the downstream plant and pipework, all of which are likely to be expensive to resolve.

Debris remains in flow

The Hendrick Passive Screen exclusively distributed by Eimco Water Technologies provides a reliable and robust physical barrier, separating marine life and debris from large volumes of water withdrawn from rivers, lakes, reservoirs and the sea. A further benefit of the Hendrick screen is that the cost for additional fish or debris handling equipment can be eliminated from the water intake design.

No moving parts

The screens, having no moving parts, are manufactured in high grade stainless steel. Large volume flows pass through its tapered bar structure at a low, uniform velocity. This unique design reduces the effects of blinding and increases the duration of uninterrupted operation between cleaning cycles.

Purpose

• Conforms to legislation and Habitats Directive

• Reduction of fish kills

• Prevention of fish entrainment

• Prevention of plant shut down

• Reduce risk of early mechanical plant fatigue or failure

• Finer openings with larger wire or bar sizes for longer weirs.

• Greater flexibility in fabricating, forming, and shaping.

Advantages

• Reliable water delivery

• Reduced civil work requirement

• Simple intake and pump station design

• Low maintenance cost

• No debris handling/ disposal issues

• Environmentally fish friendly

• Bio-fouling stays off the screen
