Recent Publications

Development of Ultrafiltration Membrane-Separation Technology for Energy-Efficient Water Treatment and Desalination Process

Woosoon, Y., Chulsung, B. 2016. Development of Ultrafiltration Membrane-Separation Technology for Energy-Efficient Water Treatment and Desalination Process. doi: 10.2172/1330442.

Why it's interesting: Pressure driven membrane-based water purification process, such as ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), can serve as a much more energy efficient and environmentally friendly method to treat water. However, membrane fouling and energy costs are a major problem. This article aims to mitigate membrane fouling and to create a fouling resistant water purification membrane. 
Application of UV Absorbance and Fluorescence Indicators to Assess the Formation of Biodegradable Dissolved Organic Carbon and Bromate during Ozonation

Li, W., Cao, M., Young, T., Ruffino, B., Dodd, M., Lo, A. 2017. Application of UV Absorbance and Fluorescence Indicators to Assess the Formation of Biodegradable Dissolved Organic Carbon and Bromate during Ozonation. Water Research, 111, 154-162. doi: 10.1016/j.watres.2017.01.009.

Why it's interesting: This study aims to determine the correlation between UV treatment and the formation of biodegradable dissolved organic carbon and bromate during ozonation. 
Formation and Reactivity of Inorganic and Organic Chloramines and Bromamines during Oxidative Water Treatment

Heeb, M., Kristiana, I., Trogolo, D., Arey, S., Gunten, U. 2017. Formation and Reactivity of Inorganic and Organic Chloramines and Bromamines during Oxidative Water Treatment. Water. Water Research, 110, 91-101. Doi: 10.1016/j.watres.2016.11.065.

Why it's interesting: This article determines the chemical characteristics of halamines using quantum chemical computations in order to be able to predict the formation of inorganic and organic halamines during oxidative water treatment.

Report Calls for Increasing Monitoring of Drinking Water Supplies in the U.S.
In response to the concerns about safety of the nation’s drinking water, the President’s Council of Advisors on Science and Technology has developed a report, which recommends increased monitoring of drinking-water contaminants, improved data sharing, and increased investments to train personnel to support drinking water systems.

Novel Mayflower Water Treatment Works Marks Milestone
The state of the art Mayflower water treatment works located at Roborough, UK, has celebrated its 300-day construction milestone. This facility will include new technology such as suspended ion exchange with a resin regeneration system, inline coagulation, and ceramic membrane microfiltration.  

Microvi and Sunny Slope Water Company Unveil World’s Most Advanced Nitrate Removal Technology
Microvi and Sunny Slope has developed Denitrovi, which is a natural nitrate removal technology that does not produce secondary waste stream, proven to provide long-term performance, and is cost efficient.  
The two National Centers for Innovation in Small Drinking Water Systems, based at the University of Colorado - Boulder and the University of Massachusetts - Amherst, are collaborative research groups charged with examining and reducing the barriers of innovative treatment technology implementation at small drinking water systems. The funding for the centers comes from the U.S. Environmental Protection Agency as part of its Science to Achieve Results (STAR) program.
