PFAS in Landfill Leachate Pilot Study

Conducted a PFAS in landfill leachate pilot study.

August 15, 2023

Overview

problem statement

Determine what technologies would be required to reduce contaminants in the leachate from an inactive landfill to below Michigan Part 31, Rule 57 surface water criteria.

target contaminants

Per and polyfluoroalkyl substances (PFAS), Hydrogen Sulfide (H2S), Ammonia, and volatile organic compounds (VOCs)

location

Trenton, MI

Equipment

Power generation and distribution for all components
Equipment fueling
External hose and piping connections
Crane services for unloading customer equipment
Weekly and on-call O&M visits
Containerization and disposal of concentrated liquid PFAS containing waste from customer provided components
Containerization, waste characterization, and disposal of spent AIX resin and GAC

Solution

Global designed, installed, and operated an autonomous break-point chlorination system to reduce H2S, ammonia, and suspended solids prior to pumping the pre-treated leachate to a customer-provided PFAS reduction system. Global also provided a 5 cubic foot anion exchange (AIX) resin bed as well as a 7 cubic foot granular activated carbon (GAC) vessel for final PFAS polishing and color removal after the customer provided components.
