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 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.

Understanding Options When Selecting An Effective, Low-Cost PFAS Solution

Municipal water utilities throughout the U.S. are increasingly grappling with the need to address PFAS once it is detected in source water. Because standards are a moving target while treatment options are limited and can represent a massive expense, addressing PFAS can be especially challenging for small water systems. 

Total Dissolved Solids: A Matter Of More Than Just Good Taste

One of the components involved in water taste is total dissolved solids (TDS), which can affect both the acceptability of finished water taste and its likelihood to corrode or clog pipes and fixtures. Here’s how to quantify the problem and what to do about it if it is excessive.

Oxidation And AOP: The Last Lines Of Defense Against Harmful Algal Blooms

Secondary metabolites of algae can find their way into source water, creating the risk that they will ultimately reach the water treatment plant to cause water-quality problems. Here is a checklist of considerations for mitigating those effects through cost-effective oxidation, or combined oxidization processes, across a variety of source water conditions.

Purifying Water From The Ground Up

The lowering of maximum contaminant levels (MCL) for contaminants such as chromium and the drilling of new wells into different geologic structures add to source water pressures. Fortunately, new technologies are helping water providers make the best of a challenging situation across a wide range of contaminants.
