Barriers to Water Reuse for Drinking Water in the US

It has been demonstrated that existing technologies for advanced water treatment can successfully upgrade wastewater to drinking water quality in large scale. There are installation for water reuse/water reclaim in California that are treating municipal wastewater to drinking water quality in volumes over 70 MGD. These technologies employed include membrane filtration, RO, UV and ozone. […]

Drinking Water Utilities Treatment Practices Based On Recent Disinfection Rules

The Long Term 2 Enhanced Surface Water Treatment Rules, know as LT2ESWTR was promulgated in 2006 obligating large drinking water utilities to comply with the rules by 2012. The rule was designed to prevent cryptosporidium, a difficult to kill pathogen from entering the drinking water supply. An incident in Milwaukee resulted in thousands of people […]

Advanced Oxidation Facilitates Industrial Wastewater Reuse

Advanced wastewater treatment technologies can allow industrial enterprises to reuse water and thus decrease industries use of fresh water resources. Currently, these processes are expensive and are probably only suitable for developed economies. This is compatible with the nature of industrial water use which increases with per capita GDP. Industries consuming the most water include […]

Ozone for the Long Term Surface Water Treatment Rule (LT2ESWTR)

Public drinking water systems will need to start complying with LT2ESWTR if sampling results indicate source waters are at risk for cryptosporidium contamination. The protozoan is capable of causing serious gastrointestinal illness. Compliance generally means additional protective measures including watershed control, source relocation, pretreatment methods, filtration, and pathogen inactivation methods. Chlorination does not control the […]

New PCB Etching Process Rreplaces Hydrogen Peroxide with Ozone

A new printed circuit board (PCB) etching process uses with ozone to replace hydrogen peroxide used in the etching solution. The invention is said to be environmentally more friendly while also producing traces just 20µm in width. H2O2 processes are seen as having broad process windows, making etching harder to control. The new process from […]

Electrochemical Ozone Generation

An interesting review article on electrochemical ozone generation will appear in the journal of Ozone Science and Engineering: The Electrochemical Generation of Ozone: A Review, Paul Andrew Christensen a , Taner Yonar b & Khalid Zakaria c a School of Chemical Engineering and Advanced Materials, Bedson Building, Newcastle University, Newcastle upon Tyne, NE1 7RU, United […]

City of Winfield, KS Has Used Ozone Since 2005

The City of Winfield drinking water department produces on average 2 MGD of water and has capacity of 6 MGD. The city has about 4,350 residential 715 commercial customers for its water. The Winfield Water Treatment facility was operational in 1969, coinciding with the completion of the Winfield City Lake. Currently, all water treated by […]

The City of Manistique Win Besting Water Using Ozone Treatment

During the 64th Annual U.P. Water Treatment System Operator’s Training, which is associated with the American Water Works Association. Manistique competed against 11 other communities in a drinking water taste off. Manistique’s water supply is drawn from the Indian River – something which sets Manistique apart form many of the other communities in the taste […]

Sand Hills Opens New Ozone Drinking Water Treatment Plant

New Jersey American Water has built a new water treatment plant in Short Hills, NJ to meet the standards of the Safe Drinking Water Act including the control of disinfection by-products. The new plant was built alongside two older plants, one that was built in 1929 and the second built in 1958. The 1958 plant […]
