Fuzhou, China, has had problems with black and smelly water in its rivers and canals for a few decades. A series of Grundfos pump gates brought flow to the water. These are solving the problem of black and smelly water, creating a better living environment along the populated riversides.
Old-fashioned chlorine gas disinfection brought risk to workers and the nearby community at Haiyan County Sandi Tap Water Company. The plant wanted a safe, reliable alternative. It chose Grundfos Selcoperm, which uses only water, common salt and electricity to produce hypochlorite.
