What is the best way to treat bacteria in water?
UV Disinfection. One of the most popular, prevalent, and reliable methods of residential bacteria treatment is ultraviolet purification. Ultraviolet light neutralizes the DNA of bacteria, preventing them from reproducing in the water.
How does ozone work in water?
Ozone is a powerful and unique water disinfectant. Ozone is extremely germicidal, and rapidly destroys any waterborne viruses and bacteria with nearly unmatched speed. Like chlorine, ozone oxidizes the bacteria and protozoa upon contact. The ozone penetrates the cell walls of the microorganisms, rupturing them on a structural level. Unlike UV disinfection, there is no reduced flow rate or extended contact time required. After shocking a well with chlorine, the chlorine must sit overnight to ensure that it has properly dismantled all the pathogens present in your water supply. Ozone, commonly seen in the house as ozonated faucets, works in a matter of minutes. Ozone is also capable of handily eliminating inorganic matter, as well as micro-pollutants like pesticides and herbicides. Ozone can also eliminate other water contaminants like iron, sulfur, and manganese.

Like Giardia, Cryptosporidium is a waterborne microscopic parasite found prevalently around the world. In fact, Giardia and Cryptosporidium (often referred to as just “Crypto”) are the two most common disease-causing waterborne parasites. Cryptosporidium bacteria will reside in the intestine of a human, causing a condition known as cryptosporidiosis. This mild gastrointestinal illness causes diarrhea, dehydration, fever, nausea, and weight loss. For those who possess compromised immune systems or preexisting health conditions, this infection can spread to other areas of the digestive and respiratory tract. When contracted by people with fragile or weakened immunities, cryptosporidiosis can develop into a chronic illness with serious health implications.
How does chlorine disinfect water?
Chlorine is used by water treatment centers across the globe to disinfect water supplies and eliminate waterborne pathogens from drinking water. Chlorine can be easily added at large scales, carefully measured, and behaves predictably, making it a widely popular disinfection choice. When chlorine comes in contact with bacteria, it breaks down the chemical bonds on a molecular level. When chlorine is added to water, a weak acid is formed. This acid, called hypochlorous acid, penetrates the negative charge of bacteria’s cell walls, destroying the microorganism from the inside out. In low and controlled doses, it is harmless to consume. While chlorine does leave a lingering chemical aftertaste to water, the water’s taste can be easily improved by a carbon filter.
