A recent paper published in the AWWA Journal (Olmos & Lodge, 105:2,February 2013, pp 41-42) discusses achieving zero water use and reasonable payback periods for a housing development in Davis California. Net zero water use as defined here is that annula water use equal annual rain fall. This would make the development sustainable from teh […]

Ann Arbor Michigan Uses Ozone for Primary Disinfection
Ann Arbor’s Drinking Water Treatment Plant’s primary source of water comes from the Huron River. Ann Arbor is one of only seven facilities using an inland river as a drinking water source in Michigan. About 85 percent of the water comes from the river, while 15 percent comes from wells located at the city’s airport. […]
Ozone Disinfection of Water Mains
Before a new water main or one that has recently under gone repair can be placed back into service, it must be flushed and disinfected. The conventional approach is to use high concentrations of chlorine for an extended period of time to kill the bacteria living in the biofilms attached to the water main surface. […]
Study Shows Electrolysis and Volatilization Can Mitigate Bromate Formation in Drinking Water
A recent study in the Journal Ozone Science and Enginnering has shown that electrolysis followed by volatilization can remove Br from drinking water and as a result lower the formation of bromate from ozone water treatment. This is an important issue since a large number of water sources contain Br ion. Ozone can react under […]
Santa Barbara to Complete Upgrade to Ozone
The City of Santa Barbara’s Cater Water Treatment Plant is being upgraded in response to stricter federal drinking water regulations. The $20 million ozone water treatment project is about 80 percent complete. The work should be completed by the end of January. Ozone will replace chlorine in the pre-treatment of water at the plant. Besides […]
ISPE Issues New Ozone Water Treatment
Ozone is widely used in the pharmaceutical industry to purify water for process applications. The International Society of Pharmaceutical Engineers has issued new guidelines on the design and use of ozone systems for pharmaceutical water treatment and sanitization. A table of contents of the updated guidelines can be found below: ISPE Guidelines Ozone Water Treatment […]
Montreal to Add a $200 Million Ozonation Plant
Medications, pesticides and hormones are emptying into the St. Lawrence River from Montreal’s water-treatment plant, but an ozone disinfection system that would remove significant amounts of those substances won’t be up and running until 2015. A team of researchers at the Université de Montréal has for years been tracking the presence of antibiotics, chemotherapy and […]
Martin’s Ferry Uses Ozone for Iron and Managanese Removal from Drinking Water
New upgrades to the Martin’s Ferry water treatment plant included ozone generators that remove iron and manganese before the water is sent to a distribution pump. The ozone generators were installed about one year ago. The plant has the capacity to produce five million gallons of water daily. Ozone is widely used to remove iron […]
Water Reuse Requires Multiple Barrier Approach
In previous posts we have talked about reuse of wastewater for drinking purposes including the feelings of Americans towards the use of wastewater for their water supply. In reality, many American’s already use wastewater as their drinking water source. If your drinking water plant is down stream of another cities wastewater plant, you are in […]
Americans Show Interest in Wastewater Reuse
Most Americans have limited knowledge about their drinking water supply,but they are concerned about it, and believe recycling water is something that should be considered according to a recent survey. However, Americans are less accepting of drinking recycled wastewater in a practice known as toilet-to-tap, the survey found. With clean water growing scarce in much […]
