WASTEWATER

Top 10 Reasons To Choose A Diaphragm Actuated Control Valve

Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This usually will require some form of a valve that will have to be controlled.  

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Looming In The Sewers: Nonwovens Are Weaving A Tangled Web
    Looming In The Sewers: Nonwovens Are Weaving A Tangled Web

    Looming in the world’s sewer system are contaminants of emerging concern.  They’re not the endocrine disruptors, antibiotics or painkillers we’ve been reading about for the past several years (though those are indeed a challenge).  These contaminants are bigger, and like the legendary alligators rumored to lurk in the New York City sewer system when I was a kid, they are growing steadily, day by day, to pose a catastrophic threat. By Jim Lauria, Senior Vice Director-Water Treatment, Bilfinger Water Technologies

  • Benefits Of IFAS For Enhanced Biological Nutrient Removal One of the major concerns regarding municipal wastewater treatment plant discharge is the rising concentration of nutrient compounds, specifically nitrogen and phosphorus.
  • Creating A Comprehensive Stormwater Model In A Challenging Environment Data including location coordinates, crown elevation, and invert depths were collected for each structure, and information such as structure dimension and composition were collected for each pipe using Global Positioning System (GPS) technology. As soon as the inventory was finished, it was converted into database format that could then be imported into the stormwater models. By Matthew Luth, Civil Engineer, Burns & McDonnell
  • White Paper: Comparison Of Stormwater Quality Treatment Guidelines And Critical Structural Best Management Performance Factors And Parameters To Consider Provisions to protect source water have become an important consideration in urban development in North America. In the United States, Phase I and Phase II of the U.S. Environmental Protection Agency’s (EPA’s) stormwater program require owner/operators to address stormwater runoff pollution issues. The program relies on National Pollutant Discharge Elimination System (NPDES) permits to implement programs and practices to control polluted stormwater runoff...

    Integrated Automation Solution Eases Water And Wastewater Operations

    The water and wastewater industries face challenges at every turn — from population growth to strict environmental and financial regulations to downsizing. The complex nature of both industries puts a great deal of pressure on plant operators, who typically tackle tasks manually. Download this datasheet to learn how integrated automation software delivers improved reliability and flexibility throughout the entire operation. 

  • Fairbanks Nijhuis Protecting New Orleans

    Originally constructed from the 1920s to 1949, the Gulf Intracoastal Waterway (GIWW) is one of America’s most remarkable transportation arteries. The New Orleans District U.S. Army Corps of Engineers operates and maintains the GIWW in Louisiana, and maintains its six locks for both navigation and agricultural purposes.

  • Cyanide Analysis Of Wastewater Samples From FCC And Hydrocracking Operations
    Cyanide Analysis Of Wastewater Samples From FCC And Hydrocracking Operations

    Fluid catalytic cracking (FCC) is a major unit operation in refineries around the world. FCC is used to convert lowvalue, high molecular weight feedstocks such as shale oil, tar sands oil, and coker gas oils into lighter, high-value products by “cracking” C-C bonds.

  • Case Study: TETRA® Denite® Denitrification Filters Meet Strict, Varying Nitrogen Limits
    Case Study: TETRA® Denite® Denitrification Filters Meet Strict, Varying Nitrogen Limits The cities of Littleton and Englewood, Colo., just south of Denver, share a wastewater plant – the Littleton/Englewood advanced wastewater treatment (AWT) plant located in Englewood. The 7886 m3/hr (50-mgd) Littleton/Englewood AWT plant serves more than 300,000 residents in the Denver metropolitan area. By Severn Trent Services
  • Filtration Is Key To Efficient Wastewater Management

    Wastewater can be defined and handled in any number of ways, from industrial process water slated for return to the environment, to reclaimed irrigation tailwater used to water crops downstream, to state-of-the-art toilet-to-tap projects. By Amiad Water Systems

  • Article: UV Light — A Brighter Disinfection Alternative Through many decades of research and development, UV (ultraviolet) disinfection technology has seen significant advances in the types of water that can be treated, the operation and maintenance of the UV equipment, and the overall cost effectiveness of a UV 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.
