Abstract
A method and apparatus for controlling zebra mussels and other bivalves using UV light from a medium pressure UV lamp which is located in a chamber having therein water in which the bivalves are located. The medium pressure UV lamp provides an intensity of UV light measured at a wavelength of 254 nm of at least approximately 6830 .mu.W/cm.sup.2 in the water. The medium pressure UV lamp provides a dose of UV light measured at a wavelength of 254 nm of at least approximately 0.1 W.sec/cm.sup.2 in the water.
Claims16
