Wastewater Treatment Case Studies and White Papers

  1. 3M™ Liqui-Cel™ Membrane Contactors Provide An Easy, Flexible Solution For Managing Dissolved Oxygen In Hard Cider

    Controlling dissolved oxygen (DO) levels during beverage production is vital for ensuring consistent product quality and shelf life. This is particularly true for canning, where high DO levels can cause breakdown of the can lining, corrosion and even leaking – which in turn can result in product waste and customer dissatisfaction. In some cases, can supplier warranties have exclusions for high DO levels.

  2. Energy And Resource Recovery: Generating Resources, Not Waste Streams

    “Sludge-to-energy” is trending in wastewater treatment, but what technologies have the most potential?

  3. Envirex® Energy Efficient Activated Sludge Process Meets Stringent Regulations While Minimizing Costs

    The Town of Elkton, Maryland, located in Cecil County near the head of the Chesapeake Bay, has a population of approximately 15,000 and an average elevation of 9.1 m (30 ft). Elkton is an economically strong, stable community that is very conscientious about environmental issues. In an effort to protect the Chesapeake Bay aquatic life, new stringent wastewater effluent regulations were implemented requiring very low nutrient levels in wastewater treatment plant discharge.

  4. Stormwater Treatment and Reuse - Toronto, Ontario (Case Study)

    Sherbourne Common is an innovative waterfront park that provides the public with green recreational space along Lake Ontario in a former industrial area. 

  5. Save Nutrients, Save The World

    While regulations demand that wastewater treatment plants get nutrients out of the water, the world’s food supply may demand more — that we recover and reuse them.

  6. The Straight Scoop On UPC/IAPMO Listed Grinder Pump Systems

    At least two major sewage grinder pump manufacturers advertise their systems as having UPC/IAPMO listings. There has been some confusion as to what this listing really means. By Kevin Clemons

  7. Refinery Expands Production While Meeting Discharge Standards Quality

    Petron Bataan Refinery wanted to expand production to process 180 thousand barrels of crude oil per day while changing its feedstock from Arab Light to less costly heavy and sour crudes.

  8. The Value Of Continuous Instrumentation To The Operator & Why Manufacturers Should Listen To Their Needs

    When I began my career as a power plant chemist most continuous analyzers were trending devices at best.  Conductivity was the most reliable analyzer and the temperature compensation algorithms were marginal.  Sample conditioning with respect to sample temperature control was not very good as well. By Randy C. Turner, Technical Director, Swan Analytical USA

  9. Chlorine Scrubber Installation Protects World-Class Water Treatment Plants In The Phillipines

    In 2014, bids were solicited to design, supply, install, and commission two Emergency Chlorine Scrubber Systems at the La Mesa Treatment Plants 1 and 2 in Quezon City, Philippines.

  10. 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.
