Screening technologies for water intakes
Bilfinger Water Technologies’ brand of Johnson Screens® passive intake screen system provides uninterrupted water withdrawal from lakes, rivers and oceans. The Johnson Screens® passive intake screen operates continuously and requires no downtime for cleaning or routine maintenance. Moreover, the system can be configured to meet US Environmental Protection Agency (USEPA) regulations for protecting aquatic life.

Bilfinger Water Technologies is the leading supplier of machines and plants in the field of water intake systems. For many decades, we have manufactured and installed thousands of bar screens and screening machines, and integrated them into overall systems – worldwide.
Premium coarse screens & fine screening machines, special solutions for fish protection, corrosion protection and isolating equipment (stop logs) are primarily used where high-grade power units such as condensers, pumps and the like require reliable protection against foreign objects.
The Business Unit GEIGER offers customised solutions for intake structures in raw water extraction from rivers and inland waters as well as in seawater extraction. These include comprehensive consultation, optimal coordination of system technology and structure, sophisticated construction adapted to the respective application as well as state-of-the-art production according to the highest quality standards.
The flexibility of the water intake systems and the use of the latest technologies and materials ensure that the individual performance requirements of the operator or plant manufacturer are fulfilled for:
- power stations (cooling water, seawater desalination)
- industrial (process water extraction, raw water extraction)
- drinking water purification (river water extraction, seawater desalination)
- water management (fish protection in bar rake and screening machines)
