Project Update from the WINSSS Center
|
|
|
The Water Innovation Network for Sustainable Small Systems (WINSSS) Center at the University of Massachusetts-Amherst is led by Dr. David Reckhow.
|
|
|
|
The WINSSS Center brings together a national team of experts to transform drinking water treatment for small water systems to meet the urgent need for state-of-the-art innovation, development, demonstration, and implementation of treatment, information, and process technologies in part by leveraging existing relationships with industry.

UMass (WINSSS/NEWIN) Mobile Pilot
Patrick Wittbold, University of Massachusetts Amherst
The UMass Mobile Drinking Water Pilot Unit is in the final stages of construction and will be ready for use by late October 2016. The pilot is capable of treating flows up to 10 gallons per minute and will be suited for a wide range of source waters. The unit is fully outfitted with innovative technologies including an advanced oxidation ozone generator as well as modern-classical technologies such as media filters and chemical feed apparatuses. The trailer is also outfitted with the most current monitoring equipment available. A key design feature of the pilot unit is the interchangeable format allowing treatment processes to be installed or removed with ease. Over the course of the next two years, it is anticipated that the pilot unit will be used to pilot the following technologies and treatment schemes:
- Ferrate oxidation
- Ozone
- Ion exchange
- Nitrification and de-nitrification
- DBP removal
- PFOA / PFOS removal
- Electrochemical oxidation processes

Impact of Natural Organic Matter on the Degradation of 2,4-dichlorophenoxy Acid in a Fluidized Bed Photocatalytic Reactor
Rezaei, R. and Mohseni, M. (2016). Impact of natural organic matter on the degradation of 2,4-dichlorophenoxy acetic acid in a fluidized bed photocatalytic reactor. Chemical Engineering Journal, (In Press). doi:10.1016/j.cej.2016.05.086.
Why it's interesting: This study revealed that NOM affects photocatalytic oxidation at low pH by scavenging positive holes on the photocatalyst surface and by scavenging hydroxyl radicals at high pH.

Impact of Natural Organic Matter Properties on the Kinetics of Suspended Ion Exchange Process
Bazri, M.M. and Mohseni, M. (2016). Impact of natural organic matter properties on the kinetics of suspended ion exchange process. Water Research, 91, 147-155. doi:10.1016/j.watres.2015.12.036.
Why it's interesting: The results of this study indicate that molecular weight and charge density of isolates play a significant role in the performance of ion exchange process for organic matter removal.

Bromide Oxidation by Ferrate(VI): The Formation of Active Bromine and Bromate
Jiang, Y., Goodwill, J.E., Tobiason, J.E., and Reckhow, D.A. (2016). Bromide oxidation by ferrate(VI): The formation of active bromine and bromate. Water Research, 96, 188-197. doi:10.1016/j.watres.2016.03.065
Why it's interesting: In certain conditions, Fe(VI) can slowly oxidize bromide and form bromate. However, under environmentally relevant conditions, the concentrations are low enough that this would not be a problem for Fe(VI) applications.

A Game Plan for Water Technology Innovation
Researchers from the Financial Innovations Lab at the Milken Institute drew on the experiences of Israel to map best practices for water industry innovation and create a framework for converting ideas to action.
Filter Made from Coffee Grounds Pulls Lead from Water
Chemist Despina Fragouli and others at the Italian Institute of Technology have created a filter made of 60 percent spent coffee grounds that removes 99 percent of the lead and mercury ions from still water in a 30-hour period.
Mueller Water Products Awarded 2016 Best Smart Water Solution at Smart Water Summit
The company was recognized for a suite of services and products, including automated flushing that helps utilities monitor chlorine residuals and other water quality conditions.
U.S. Senator Tammy Baldwin Champions Water Infrastructure and Safe Drinking Water Investments Passed by U.S. Senate
The Water Resources Development Act of 2016 passed earlier this month incorporates elements from the previously authored Water Technology Acceleration Act, including a program to fund public-private partnerships that deploy, test, and improve emerging water technologies.
NJ Proposes Stringent Standard to Control Cancer Chemical in Water
The New Jersey Drinking Water Quality Institute has proposed a standard that would require water utilities to treat PFOA, which small utilities say could be cost prohibitive.

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.
