ATLAS-SSI - Model 316(B) - Compliant Fish Handling Screens
ATLAS-SSI is the industry`s preferred partner for 316(b) project planning, engineering and manufacturing for both new and retrofit applications. Our Modified Ristroph Fish Handling Traveling Water Screens are currently in use around the country in both the Thru Flow and Dual Flow designs. Our fish handling baskets reflect “Best Technology Available” (BTA) and we have demonstrated this in the lab and field. We design and manufacture them to withstand the extreme operational demands of their intended environment.
Thanks to our 30 years of industry experience, we also incorporate features into the design to address various potential maintenance issues. We offer fine and coarse screening options on all styles of screens.
We introduced our SmartScreen Technology® primarily to control every screen design and operation aspect. We accomplish this by correctly selecting screen design and components and maximizing screen life through condition-based operation.
We utilize a real-time automation system based on the actual operating conditions of the screen, such as differential pressures, screen speeds, and seasonal events.
- Tested and proven marine survival technology
- Superior debris removal and discharge capabilities
- Engineered and manufactured to limit maintenance
- Rugged, heavy-duty reliability
- Outstanding factory support
- American Made In the USA
We can also take your existing screen and upgrade it to “fish ready” or “fish handling.”
- Fish Ready: We upgrade your screen components to a level that minimizes the upgrades at the time you need to be compliant.
- Fish Handling: We can return your fully fish handling screen ready to comply with EPA 316. This option includes modified Ristroph baskets, an extended head section, and a fish-return system.
In 2014, the EPA issued its “Final Rule” regulating the cooling water intake structures of existing facilities that are designed to withdraw at least two million gallons of raw cooling water per day from U.S. waters.
Each regulated facility requires an NPDES permit, which is designed to protect biological organisms and reduce impingement (organisms trapped against the front of an intake structure) and entrainment (organisms passing through the cooling system). 316(b) further requires that the modified Ristroph system be optimized following installation.
Optimization refers to both biological optimization and mechanical optimization. Each cooling water intake structure is unique, and the environmental concerns at each facility vary and require individual analysis.
Various conditions such as fish species, water velocities, intake design, pump location, and many other factors mean that there is no off-the-shelf, one-size-fits-all compliance to 316(b). ATLAS-SSI understands that and will support you through this process.
