Municipality Removes Biofilm, Improves Water Quality, Lowers Dosage With MIOX
Looking to reduce potential disinfection byproducts issues that new and difficult regulations were requiring, a Tennessee municipality began investigating alternative water treatment disinfection methods in an effort to reduce the potential liability (RMP) involved with using and storing gas chlorine. Within months of switching to a mix of oxidants (MOS), a difference was noted in the systems residual, residual was no longer dead spotting in low flow areas, and much higher residual was noted in areas that had been difficult to maintain At the end of the first year of operation the municipality had also documented a reduction in their disinfection byproducts formations, specifically both TTHMs and HAAs, which were both reduced by 50% in direct comparison with the quarterly results from the previous year.

Technology Qualification Of Liqui-Cel® Membrane Contactors For Deoxygenation Of Low Salinity Water For Polymer Flooding
Polymer flooding using low salinity water has been shown to improve oil reservoir recovery rates by altering the reservoir characteristic from an oil-wet state to a water-wet state. It has also been shown to be cost competitive with other Enhanced Oil Recovery (EOR) processes. The combined cost savings and increased recovery rate have prompted a lot of attention in the polymer flooding process with low salinity water in recent years.

Organics Monitoring (TOC)
Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small.
Application Note: Vertical Profiling Safeguards Drinking Water And Sheds Light On Cyanobacteria A search for algal toxins in North Carolina reservoirs has evolved into an ongoing early warning system for three important drinking water reservoirs—which serve two large cities—and yielded a greater understanding of the dynamics of blue-green algae, or cyanobacteria, in the state’s reservoir system.

Decrease Membrane Treatment Capital And O&M Costs With Optimum Flux Rates
Despite a global effort to standardize units of measure to the metric system, the water treatment industry still follows the U.S. trend in resisting that directive by referring to water volumes in treatment plants as gallons per day (GPD). While achieving a specified permeate GPD is certainly important in overall membrane plant design, production capacity has absolutely nothing to do with determining optimal methods of treating site-specific feedwaters and offers no indication of potential membrane fouling rates and related maintenance costs. To evaluate these factors, knowledgeable professionals rely on membrane flux rates as the key consideration in achieving optimal system design and operation. By Harold G. Fravel Jr., Executive Director, American Membrane Technology Association and Karen Lindsey, VP, Avista Technologies, Inc.
The UV Uprising: How UV Disinfection Will Claw Its Way To Prominence
Chlorination in all of its forms — gas, liquid, or solid — has been the primary way for treatment plants to disinfect the treated wastewater. The treatment plants that use gas chlorination must face federal regulatory oversight in the form of a Risk Management Program (RMP). Liquid chlorine plants trade in the regulatory oversight for a more expensive and less effective product. While chlorine in its solid form is good for small treatment facilities known as package plants (named for their mobility). However, ultraviolet (UV) technology is rapidly altering the landscape of disinfection throughout the industry. By Sheldon Primus, MPA, COSS
Has Fracking Gone ‘Green’?
There are few topics more controversial these days than hydraulic fracturing ("fracking"). While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.
