Chlorine is and has been the No. 1 disinfectant used by water treatment systems throughout the world for more than 100 years. Currently, a majority of municipal water systems use chlorine to disinfect their drinking water. Recently, though, concerns over chlorine’s limitations have emerged, and research into alternative disinfectants is ongoing.
New disinfection options may provide alternatives to traditional chlorine
As winter becomes nothing more than a memory and the days get warmer, our thoughts are quickly turning to the lazy, hazy days of summer. And nothing is more refreshing on a hot summer day than a dip in the pool.
UV systems offer treatment option with fewer chemicals
Reading the Centers for Disease Control and Prevention’s (CDC) Web pages on recreational water illnesses (RWIs) is enough to make someone never want set foot in a swimming pool again. From the list of pathogens that can cause RWIs (which includes some nasty fellows, such as Cryptosporidium, Legionella, E. coli and more) to statistics on sources of disease (“on average, people have about 0.14 grams of feces on their bottoms”), the cringe factor is high.

It is driven by a cell phone battery that can be charged by the integrated solar panel or USB, and is able to treat 300 liters of water per charge. There is an LED flashlight for nighttime operation.
