Portland, Maine Upgrades Water Treatment Plant with UV and Ozone
A major upgrade to the Sebago Lake Water Treatment Facility has been started for the Portland Water District’s treatment facility in Standish at a cost of a $12.8 million. It adds two UV reactors as well as an upgraded ozone water treatment system. The Water District has been designing this system since 2002. Engineers with […]
NSF Presents Papers on UV and Ozone Water Treatment
NSF International water quality and treatment experts will be presenting at the World Aquatic Health Conference October 11 in Norfolk, Va., according to a press release. Their presentations will cover the regulatory and testing considerations for evaluating the efficacy of ultraviolet (UV) and ozone water treatment technologies to help ensure the health and safety of […]
Ozone Eyed for Ballast Water Treatment
In previous posts we have noted work on the use of ozone in ballast water treatment. IMO rules will require ships to treat ballast water to prevent the transport of invasive species across the globe. As an example of invasive species brought to the US via ballast water are zebra mussels. The new rules will […]
Ozone Water Treatment – Removal of Organic Compounds
Ozone is often used to reduce the amount of organic compounds in water treatment applications via a process called oxidation. Commonly used measures of organic levels are COD (chemical oxygen demand) and BOD (biological oxygen demand). The first measure uses high temperature and aggressive chemical oxidants to completely oxygenate organic compounds in a test sample […]
Ozone and Advanced Oxidation Find Opportunities in Fracking Water Treatment
Fracking has created a large application for various water treatment technologies such as ozone and advanced oxidation processes. Both processes have been used to either breakdown organic contaminants in the water, remove Fe and other minerals or for disinfection of the water prior to injection. An advantage of ozone based processes is that the ozone […]
Salt Lake City Uses Ozone to Improve Water Quality
Salt lake City uses ozone at two of its facilities: Little Cottonwood (LCW) and Point of the Mountain (POM). LCW has Utah’s first and largest ozone drinking water treatment system, two ozone generators each sized at 3,750 lb/day of ozone. The facility can treat 143 MGD of water. The plant can dose ozone at 3.5 […]
Poughkeepsie Looks to Ozone To Treat Drinking Water
New federal drinking water standards could require the Poughkeepsie water plant to make $16 million in upgrades. The U.S. Environmental Protection Agency is requiring municipal water plants to do more to restrict disinfectant byproducts (DBP) in drinking water that could pose health hazards. Poughkeepsies’ Water Treatment Facility is looking at injecting ozone into the drinking […]
Singapore’s River Safari Uses Ozone Water Treatment
Singapore operates a number of parks under its Wildlife Reserve brand. These include the Singapore Zoo, Night Safari, and the Jurong Bird Park. The newest park is River Safari, the first river themed park in Asia. It will include eight major rivers from around the world including the Mississippi, Congo, Nile, Ganges, Murray, Mekong, Yangtze […]
Ozone for Disinfection By Products Control in Drinking Water
Disinfection of drinking water often involves a trade off between inactivating pathogens and creating undesirable disinfection by products in water. Because chlorination is still the most widely used method of disinfection, problems with the formation of chlorinated byproducts due to the interaction of chlorine with organic compounds found in water is a major issue. Two […]
