Speed student using solar energy to purify water
It looks a bit odd, but it just might revolutionize the way we clean polluted water.
Venkata Gullapalli, a UofL graduate student at the J.B. Speed School of Engineering, is developing a system to purify water from Beargrass Creek using solar power, tanks, pipes and a concrete waterfall.
Six solar panels power a pump that sends water from the polluted creek uphill to a 10-foot-high, 1,200-gallon tank. From there, the water seeps through sand, gravel and crushed oyster shells and makes its way to four troughs open to the sun. Ultraviolet rays kill bacteria in the water.
