Per & Poly-Fluoro Alkyl Substances PFAS
- Group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water.
- They are called the forever chemicals because they do not break down in the environment.
- Found in the blood of people, animals and in a variety of food products and in the environment.
- Exposure to some PFAS may be linked to harmful health effects in humans and animals.
- In April 2024, the USEPA released the final PFAS regulation limiting the drinking water maximum contaminant levels (MCLs) for PFOA and PFOS to 4ppt (parts per trillion), PFHxS, PFNA and GenX to 10ppt and a Hazard index of less than 1.0 (unitless) for 4 other compounds.
Product Description & Features
EMCO PFAS Removal Systems based on Ion Exchange Resin are an excellent choice for the removal of PFAS from potable water applications. The system is based on a Strong Base – Single Use resin that’s able to capture short and long PFAS chains and its performance far exceeds the current EPA guidelines.
All EMCO’s Ion Exchange IX systems for PFAS removal have the following Features:
- Can be loaded with a dual media bed to remove Arsenic in Addition to PFAS.
- Retrofittable system to that can be operated with GAC or IX resins.
- High selectivity resin for both short and long chain PFAS removal.
- Ideal for ON/OFF operation. PFAS tends to Slough off GAC at restart.
- All our vessels are ASME Stamped with NSF approved coating.
- Manufactured in the US with the option to manufacture it overseas.
- Underdrain Design Flexibility with Drop Header & Lateral or Septa.
Under-drain system for ease of media unloading.
Disclaimer
Smooth operation of the resin system is dependent on influent water quality. Specific pre-treatment requirements are to be met (refer to manufacturer for more details)
