A New Generation! The Army Corps of Engineers have designed a hydroelectric turbine that’s safer for fish, increase energy efficiency by 4%
They’ve recently installed a new design that’s improving energy efficiency and improving fish survival along the Snake River, with plans to upgrade more turbines over the next several years. The Army Corps installed the first of two designs at Ice Harbor Dam, just outside the Tri-Cities in southeastern Washington. A second blade design should be finished in 2021. “It really is a new generation of turbine design for our hydropower system,” said the Corps’ Martin Ahmann.,, This new turbine has been shown to increase juvenile fish survival rate to more than 98%. >click to read< 10:50
Wastewater Treatment Plants: Pharmaceutical fish – SCSU experiments
An experiment that started last week in St. Cloud State University’s Aquatic Toxicology Lab expands upon 2012 studies that determined fish might be affected by pharmaceuticals entering rivers and lakes through wastewater treatment plant effluents. Using larval and adult fathead minnows, it looked at individual and combined exposure to sleep aids, muscle relaxants, painkillers and antidepressants — chemicals previously detected in the environment. Juvenile fish didn’t get as big or escape as fast. Adult females had larger livers. Adult males,,, Read the article here 11:33
