• PFAS Beyond Removal: 7 Often-Overlooked Factors

  While performance and cost matter, there are a range of other factors that can have a substantial impact on the overall viability and success of a solution.

• How To Pull A Representative Activated Carbon Sample (And Why It Matters)

  Analyzing a GAC sample reveals if the media should be reactivated or disposed of. Therefore, it is critical that operators follow this definitive guide for pulling a representative sample.

• Underdrain Designs: Why The Internal Cone Is The Most Economical Choice

  A poor underdrain design can cause filtration inefficiencies and inconsistencies, including uneven pressure drops and dead zones where water flows slowly or not at all.

• How To Properly Start-Up And Condition A New Granular Activated Carbon Bed

  Bed conditioning and startup procedures are designed to optimize the performance of the carbon bed and maximize adsorption capacity to achieve treatment goals.

• Four Tips For A Successful PFAS Removal Pilot Study

  Follow these key steps to conduct a successful pilot study to help remain below their target contaminant limits and cost-effectively comply with regulations.

• Decontamination In Days: How Calgon Carbon Cleaned Pearl Harbor

  A first-hand account of how Calgon Carbon Corp. executed a last-minute clean jet fuel contaminated water around the Joint Base Pearl Harbor-Hickman.

• VOCs For Non-Scientists: Understanding, Detecting, Removing

  This introduction to volatile organic compounds (VOCs) will discuss what qualifies a compound as a VOC, how to detect them, and how to treat and remove these chemicals from the water system.

• Minimizing Disinfection Byproducts By Targeting Natural Organic Matter Precursors

  Water treatment plants (WTPs) need to lean less on the disinfection process strategies (i.e., chloramination) and instead focus on more comprehensive DBP solutions such as removing TOC. Here's why.

• Refining GAC Solution Costs For PFAS And Other Contaminants

  Whether a water treatment plant (WTP) is evaluating a new granular activated carbon (GAC) solution to deal with contamination problems such as PFAS, DBPs, and VOCs or looking to enhance existing GAC performance, it is important to assess treatment processes in the full context of source water quality. Here are some ideas to help decision-makers achieve the best outcomes at the lowest total lifecycle cost.

• Optimizing PFAS Removal In The Presence Of Other Contaminants

  Here are some considerations that can help water treatment plant (WTP) supervisors, operators, and their consulting engineers achieve their PFAS removal goals more efficiently and cost effectively despite the added challenges.

• The Significance Of NSF System Certification For Water Utilities: Understanding Its Importance

  NSF-certified systems have the same benefit as individually certified components but can often be produced more cost effectively.

• Groundwater vs. Surface Water: A Treatment Comparison

  This article will discuss two of the most common drinking water sources and how they affect treatment priorities and configurations.

• Is IX Or GAC Better For Removing Short-Chained PFAS Compounds?

  In this episode of Water Talk, Angela Godwin sits down with Adam Redding from Calgon Carbon Corporation to talk about PFAS and more.

• Third-Party Validated PFAS Destruction Story

  Read about a stack testing program at a full-scale GAC reactivation facility during the reactivation of a load of GAC known to contain adsorbed PFAS. 

• How And When The EPA’s Proposed PFAS MCLs Could Impact The Drinking Water Industry

  The U.S. EPA recently announced its proposal for what would be the first-ever national drinking water standards for PFAS. This news likely triggered several questions about what this means to the drinking water industry. Here, we will address some of the most important ones.

• How Biogrowth Can Aid In Disinfection Byproduct Removal

  Learn how naturally occurring biological growth on carbon media can help enhance removal of total organic carbon (TOC) and thusly reduce the formation of DBPs.

• Evaluating A Dual Media (IX/GAC) Approach For PFAS Removal

  In this segment from Virtual Water Expo, Dr. Adam Redding discusses a dual media (IX/GAC) approach for PFAS removal. 

• How Does Operation And Maintenance Of Activated Carbon Compare To Ion Exchange Technology?

  Water treatment plants (WTPs) that deciding between ion exchange (IX) or granular activated carbon (GAC) systems should weigh the operation and maintenance of each before implementing either technology.
