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 […]
On Site Oxygen Generation for Ozone Production Using Pressure Swing Absorption
Ozone is most efficiently made from oxygen with a small amount of nitrogen. Oxygen exists in the atmosphere at a concentration of about 21% in air we breathe. Using technologies such as pressure swing absorption (PSA). PSA is a purely physical process; there are no chemical, electrical, or other reactions in our process. Under pressure […]
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 […]
Algae Control Using Ultrasound
Normally, this blog focuses on ozone and advanced oxidation technologies for water and air treatment. An interesting non chemical water treatment for algae control might be of interest to the readership of the blog. Algae blooms can create both aesthetic and other problems for tanks, ponds and lakes. Chemical treatments are routinely used, but require […]
Ontario Studies Advanced Oxidation for Wastewater Treatment
Ontario is investing in innovative solutions to help protect Great Lakes water quality. The Keswick Water Pollution Control Plant is testing an advanced oxidation process to reduce the amount of phosphorus and micro pollutants such as pharmaceuticals and personal care products entering Lake Simcoe. Advanced oxidation processes have been demonstrated to remove pharmaceutical and personal […]
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 […]
