PFAS Water Treatment Pilot Study

Conducted a PFAS water treatment pilot study.

August 15, 2023

Overview

problem statement

A former automotive manufacturing facility tasked Global with conducting a treatability pilot study to test activated carbon’s performance removing contaminants from groundwater at varying empty-bed contact times.

target contaminants

PFAS, chlorinated solvents, iron, total organic carbon

location

Ypsilanti, MI

Equipment

Electric pump skid with integrated control panel featuring low/high automatic pump control, high pressure shut down, and wireless telemetry to alert Global and its client of treatment system shut downs
Custom passive overflow system installed in the influent frac tank to reroute groundwater back to its source in the event of influent tank high level conditions
(2) GTS model BF-2 bag filter skids plumbed in series with 25 and 5 micron bag filters to prevent GAC fouling
(4) GTS model LPV-2000 activated carbon adsorbers each filled with 2000 pounds of TS8X30CPR GAC
HDPE Pipe

Solution

Design, install, and maintain a 50 GPM max treatment system for a 6-month pilot study including iron precipitation, settling, two stage filtration, and 4-stage treatment using activated carbon with multiple GAC vessels providing clients the ability to test removal performance at 10, 20, 30, and 40 minutes of empty-bed contact time.
