The Disinfecting LET’S Muscle of UV and RELY OzoneON

n 1861, one man changed the world. Louis Pasteur published his theory on microorganisms, opening a new front in the battle against tiny creatures that cause humans great agony. Pasteur, along with many contemporaries, opened our eyes to a world beyond our sight and the means to reduce its harm. Today, food lasts longer, and a minor infection is no longer a death sentence. Ironically, one of the greatest germicide defences known to the world was discovered 60 years prior by Johann Ritter: ultraviolet (UV) light, and in the 1930s, William F. Wells noted that UV attacks airborne diseases.
PROVEN utility water to new levels: “UV and ozone are very potent, but the technologies had admittedly been demanding to implement and sustain. Consequently, water treatment relies heavily on chlorine, which is highly effective and inexpensive.
helped improve results without adding more management overheads. The self-contained systems often reduce the cost of established chemical purification regimes.

WATER. But it has drawbacks, such as chemical contamination, corroding infrastructure and requiring special facilities and skills to stockpile and operate at scale. What we’re seeing in the market is water treatment managers are adding UV and ozone systems to reduce chlorine reliance, and use these systems where chlorine isn’t feasible.”
In situations where using chemical disinfectants are impractical - such as cleaning public areas, including hospital rooms or taxi ranks - mobile Wedeco ozone and UV systems are highly effective. Wedeco has developed these technologies for over 40 years, an investment that is paying out handsomely for Xylem customers, says Mistry: “Xylem’s Wedeco brand has transformed the industry by drastically reducing the carbon footprint of water treatment plants around the world with highly-efficient, reliable and environmentally-friendly technologies.
For example, Xylem deployed its Wedeco UV and ozone systems to eliminate bad tastes from A decade after Pasteur, water served by the Anderson Cornelius Fox realised that ozone Regional Joint Water System, gas is a potent disinfectant We are very proud of the which provides potable water to Today, public utilities use both brand’s strong heritage 14 water utilities in Upstate South technologies broadly to manage and look forward totreatment future Carolina,diffused USA.
