Revolutionizing Municipal Water Treatment: Advanced Shallow Sand Filtration for PFAS Containment

Industry Challenge:

• 74% of municipal plants report rising PFAS/PFOA contaminants exceeding EPA advisory levels (4 ppt)

• Conventional sand filters show ≤60% removal efficiency for sub-100nm particles

Technology Deep Dive:
Next-gen shallow sand filtration systems now integrate:
✅ Activated alumina layers (0.5-1mm) boosting PFAS adsorption by 8.2x
✅ Electropositive media capturing negatively charged colloids
✅ IoT-enabled backwash optimization reducing water waste by 35%

Impact Metrics:

"After retrofitting with multi-media shallow sand systems, Durham Water Authority achieved:

• 99.2% PFAS removal (from 120ppt to <1ppt)

• 40% longer filter runs

• $280k/year chemical savings"*
