Drinking Water Case Studies and White Papers

91. Arsenic Successfully Removed In the Mojave Desert With SORB 33 Arsenic Removal Systems 4/13/2017

    The Moapa Valley is a fertile stretch of land In the Mojave Desert, 50 miles northeast of Las Vegas. Nourished by a network of artesian springs which bubble up from deep underground, the land for years produced carrots, spinach, cantaloupe, tomatoes and potatoes and today produces primarily alfalfa and onions.

92. How Valve Insertion Can Underpin Sustainability 7/2/2021

    To save money and protect the environment, municipal water systems are increasingly under pressure to adopt sustainable practices. However, progress in this area is often hampered by a wide array of issues. As an alternative to traditional valves, the use of valve insertions has emerged as a sustainable maintenance solution.

93. How To Conduct Water Quality Analysis For Ozone Disinfection 5/24/2018

    Because ozone is relied on so heavily to oxidize a wide variety of potential wastewater contaminants, water quality analysis during the disinfection process is paramount. Once the ozone process itself is understood, its water quality ramifications and the quality parameters that offer insight into its efficacy can be analyzed and taken into account.

94. Automation Solutions For Fixed-Bed Filters 2/5/2015

    Handwheel or automated process valve? The worldwide trend is clearly moving towards automation, because it reduces energy and water consumption, especially rinsing water, and increases plant availability. Pneumatic automation of a fixed-bed filter is a good example of this.

95. How Small Utilities Can Afford To Reap The Benefits Of Large District Metering Solutions 7/1/2020

    Water scarcity issues and increased production costs are putting more pressure than ever on small water utilities, which tend to rely on relatively few personnel to deliver a quality, affordable product to consumers. The good news is that proper flow metering technology and resulting data can help ensure that water quality and service in smaller communities remain on par with larger systems.

96. How Targeted Investments By Private Water Can Boost Public Support 10/30/2019

    A significant number of utilities operating in smaller regions where resources are strained, and where the daily business of water treatment can be exceedingly expensive, have turned to privately owned companies to manage their drinking water and wastewater operations. The downside is that this arrangement also tends to bring heavy scrutiny from a public that expects the provider to put service above the bottom line. Fortunately, targeted investments in solutions can address the issue.

97. Las Vegas Valley Water District Utilizes Field Tools App And iPhones To Expand Functionality 8/26/2021

    The Itron Field Tools mobile app has allowed for our Field Technicians to use their iPhones as a multifunctional device. The Field Tools App also allows us to upgrade with minimal involvement from our IT teams.

98. THM Removal System Successfully Removes Over 65% Of THM Species In Water Storage Tank At The End Of 60 Mile Transmission Line 7/16/2018

    In Canada and the western United States, long treated water transmission lines are frequently utilized to convey potable water to rural communities. These long transmission lines combined with chlorine for water disinfection can often create the requisite conditions for the formation of undesirable disinfection-byproducts (DBPs). One of the most common DBPs is a family of volatile compounds called Trihalomethanes (THMs) which are regulated in Canada to a level of 100 ppb (part-per-billion) annual average and in the US to a level of 80 ppb.

99. Water Reuse Strategies: Steel Industry Case Studies 3/18/2011

    Successful reuse of water back into industrial water applications requires a comprehensive understanding of process design, water chemistry, membrane systems, chemical treatment, instrumentation and control. By David Christophersen, Technical Support Manager, Crown Solutions

100. Do We Have To Sacrifice Performance To Be Green? 11/25/2013

     The global use of membranes is widespread in municipal, industrial, and wastewater applications with reverse osmosis (RO) proving to be a highly effective and reliable method of advanced water treatment.  Reuse applications have been particularly challenging for water treatment chemical companies as these highly variable feedwaters can contain any imaginable constituent, resulting in a wide array of site specific foulants.
