Have you ever wondered how wedge wire can be used to help the environment? Well, it just so happens that civil engineers designed a cylindrical wedge wire screen to greatly reduce the entrainment and impingement of Hudson River fish. This screen allows water to filter through before it enters the plant’s cooling system, eliminating the chance of backing up the water pumps.
The wedge wire screen was designed to keep out fish, fish larvae and fish eggs, which are all larger than the size of the slots in the screen. Plus, the velocity of the flow-through slots runs at 0.5fps or less, which eliminates the chance of extrusion. It’s amazing to think about what a simple solution like wedge wire has done for the local ecosystem of the Hudson River community.
