Landfill owners modelling PFAS exposure for 2027 should stop trying to reduce it to a single number. The federal picture is less settled than most board packs suggest: EPA’s proposed rule to list nine PFAS as RCRA hazardous constituents was withdrawn on 8 May 2026, while the drinking water limits for PFOA and PFOS remain…
Why Suspended Solids Matters at Every Stage A landfill leachate treatment train produces suspended solids challenges at essentially every stage: Raw leachate arrival: highly variable TSS, sometimes as high as 3,000 mg/L after a heavy rainfall event. Equalization tank: mixing and settling combine to produce a stratified TSS profile. DAF (dissolved air flotation): designed to…
Why the Two-Step Architecture Changed the Sourcing Question For most of the last decade, PFAS treatment was a single-step problem: adsorb the compounds on GAC or ion-exchange resin, incinerate the spent media, and file the compliance paperwork. That approach is now widely considered inadequate for high-concentration streams like landfill leachate, because it displaces rather than…
The 2026 Field Playbook for Lithium Water Instrumentation by Shanghai ChiMay Lithium producers in 2026 face a very different instrumentation challenge than they did five years ago. Old evaporation pond operations tolerated weekly grab samples and paper logbooks. New DLE plants, integrated brine-to-carbonate facilities, and hard-rock spodumene concentrators need continuous, high-resolution monitoring on every important…
Inside a Modern Gigafactory: How Sensor Networks Guard Battery Yield with Shanghai ChiMay Walk into a modern EV battery gigafactory and the scale of the operation hits first: cavernous coating rooms, calendaring lines that stretch for a hundred meters, dry rooms held at dewpoints below minus forty. Look past the mechanical scale and a subtler…
How Inline Conductivity Sensors Track Solvent Purity in Slurry Coating Lines: A Shanghai ChiMay Technical Guide Slurry coating is the beating heart of every lithium-ion cell factory. Cathode and anode slurries are engineered blends of active material, binder, conductive additive, and solvent, and their electrical behavior can shift within seconds if solvent purity drifts. Because…
