Walking Through a Destruction Facility Imagine walking through a PFAS destruction facility with a plant tour guide. The visit starts at the raw feed intake, moves through storage tanks, pre-treatment, foam fractionation, destruction reactors, cooling, neutralization and finally to discharge. At every stop, sensors are running quietly, feeding data to the plant historian and to…
Why UV-Absorbance for COD? Chemical oxygen demand has historically been measured by sealed reflux digestion with potassium dichromate and sulfuric acid followed by titration or colorimetry — a multi-hour laboratory workflow (the standard dichromate method takes roughly two hours of digestion alone, per SM 5220 D / EPA 410.4; note that the familiar “five-day” test…
Why Instrument the Reinjection Line at All? Leachate reinjection — where collected leachate is pumped back into the waste mass to accelerate stabilization or manage volume — is not a new technique. What has changed is the compliance framing around it. PFOA and PFOS are now designated hazardous substances under CERCLA, state agencies are taking…
Chapter One: Capture For most of the last decade, PFAS treatment meant capture. Granular activated carbon columns adsorbed short and medium-chain PFAS from municipal drinking water. Ion exchange resins targeted specific PFAS species with higher selectivity. Reverse osmosis and nanofiltration barriers rejected PFAS by size and charge. All three techniques share a common structural feature:…
Pain Point 1: Wildly Fluctuating COD Load Landfill leachate concentration is not steady. A young landfill in a wet climate can present raw leachate COD in the tens of thousands of mg/L, and the load can swing by a factor of several across a wet week, driven by rainfall, waste age and internal biological activity….
Key Takeaways The current shift in waste utility capital planning isn’t primarily about treatment technology — it’s about the sensor and data architecture that makes every downstream investment defensible and financeable. Traditional 20-year leachate CAPEX plans, built on fixed treatment assumptions, are giving way to data-anchored plans that use continuous monitoring to stage risk-adjusted investments….
