With upcoming EPA regulations on PFAS in drinking water, utilities are racing to find effective removal technologies. While performance and cost often dominate the discussion, a recent article from Calgon Carbon Corporation published on Water Online highlights seven crucial factors that water treatment professionals must consider beyond these basic metrics.
The three main technologies currently used for PFAS removal are granular activated carbon (GAC), ion exchange (IX), and reverse osmosis (RO). However, before selecting any solution, utilities should evaluate several often-overlooked aspects:
Operational complexity and the demands on plant operators, who typically manage multiple processes simultaneously. Complex systems requiring constant monitoring can lead to operational challenges.
Operator certification requirements, which vary by state and technology type. Treatment facilities need qualified operators before system implementation.
Public confidence considerations, particularly how easily the technology can be explained to concerned consumers.
Technology maturity and proven track record, especially important in an industry where public health is at stake.
Vendor technical support capabilities for troubleshooting and optimization.
Media disposal options and their associated costs, particularly relevant with new EPA RCRA proposals for PFAS.
Impact on other water quality parameters, as many facilities need to address multiple contaminants simultaneously.
The article emphasizes the importance of thorough research, proper pilot testing, and learning from other utilities’ experiences. For a detailed examination of these factors and guidance on conducting effective pilot studies, read the complete article here.
Understanding these factors can help utilities avoid costly mistakes and ensure successful long-term PFAS treatment implementation.
