‍PFAS pilot testing is a critical step in designing effective treatment systems for removing per- and polyfluoroalkyl substances from water. We have a pilot scale with four columns shown here.

Here's what Pilot testing achieves:
 • Validates Treatment Technologies
○ Confirms whether proposed systems (e.g., granular activated carbon, ion exchange, reverse osmosis) effectively remove PFAS under site-specific conditions.
‍
• Optimizes System Design
○ Helps determine the best media type, flow rate, contact time, and configuration for full-scale implementation.
‍
• Identifies Breakthrough Points Tracks when PFAS begins to appear in treated water, helping estimate media lifespan and         
       ○ replacement schedules.
‍
• Supports Regulatory Compliance
○ Provides data to meet local, state, or federal standards for PFAS removal and reporting.    
‍
• Reduces Long-Term Costs
○ Avoids overdesign or underperformance by tailoring the system to actual water chemistry and PFAS concentrations.

‍Here is how PFAS Pilot Testing Is Done
• Site Characterization
○ Collect water samples to analyze PFAS types and concentrations.
○ Assess other water quality parameters (e.g., pH, TOC, hardness) that affect treatment.

• Bench-Scale Jar Testing (optional)  
○ Small-scale lab tests using different media to screen for effectiveness.

• Pilot System Setup
○ Install a scaled-down version of the treatment system at the site.
○ Use real influent water and simulate operational conditions.

• Sampling & Monitoring
○ Regularly collect influent and effluent samples.
○ Analyze for PFAS (including branched and linear isomers) using EPA-approved methods like EPA 533 or EPA 537.1.

• Data Analysis
○ Evaluate removal efficiency, media exhaustion rates, and operational stability.
○ Adjust system parameters as needed.

• Reporting & Scale-Up
○ Use pilot data to design full-scale systems and support funding or permitting application
