From Nevada to South Dakota and now Tennessee, cities across the U.S. are installing the AMERICAN Flow Control® ALPHA restrained joint, because it saves labor, time and money. Introduced almost a year ago, ALPHA is used on AMERICAN’s Series 2500 4- to 12-inch Resilient Wedge Gate Valves and American-Darling and Waterous fire hydrants.
Water hammer events can result in service issues for utilities, as the sudden increase in pressure can contribute to pipe fatigue, eventually causing pipe failure—a costly situation for municipalities.
A $12-million public and private research project, the Nebraska Innovation Campus (NIC) in Lincoln, Nebraska, is a combined effort of the University of Nebraska Lincoln (UNL) and the private sector and aspires to be the most sustainable research and technology campus in the United States.
Disinfection is by far the most common use for ozone in water and wastewater treatment applications. The basics of ozone dosing / sizing have been discussed at length in any number of our previous articles. In this article, we are trying to provide better insight into decoding the why’s and how’s of your next ozone disinfection application. By Louis LeBrun, PE Thoram Charanda
When the Cobb County-Marietta Water Authority (CCMWA) anticipated the need to upgrade the Hugh A. Wyckoff water treatment plant, they turned to granular activated carbon (GAC) technology after vetting several alternatives. The plant, a wholesaler in a two-plant system, processes up to 72 million gallons per day and serves about 350,000 people. Comprising of Wyckoff and the James E. Quarles treatment plant, CCMWA is the second largest water provider in Georgia.

Located on Lake Michigan 12 miles north of downtown Chicago, Evanston was named in 1857 for one of the founders of renowned Northwestern University, which predated its surrounding municipality by a couple of years.
The idea that membranes could be used for solids removal and concentration in potable water treatment schemes has been known for hundreds of years. It has only been in the past 50 years or so that reverse osmosis membranes for treating brackish waters or sea water have been considered a cost-effective viable alternative. More recently, the membrane suppliers have produced low-pressure membranes that are applied in current treatment process schemes to enhance the water quality effluent required to meet additional regulatory guidelines
Water scarcity is requiring large industrial plants to investigate conservation options, including reuse of municipal wastewater effluent, in order to grow sustainably while meeting increased demands for fresh water make-up.
Water — our most precious resource — is depleted globally by multiple activities. Common uses include drinking water, fire protection, agricultural/irrigation, manufacturing, food processing, etc. As our global population continues to increase, so does the need for fresh water supply. As a dynamic resource with many universal commitments, it is not surprising, with so many different global variables, that water scarcity is becoming a concern for both developed and developing countries.
