Wastewater Advocacy and Innovation with Robin Deal

"The More You Know" - Robin Deal
A million-gallon-a-day perspective, distilled into actionable steps. Robin Deal, AquaPure Product Manager at Hubbard-Hall unpacks how seasoned pros can squeeze more performance—and less sludge—out of industrial wastewater systems without compromising compliance or plant uptime.
From "clear water in a jar" to stable discharge in the field
Robin details a practical jar-testing workflow: start from upstream processes, target pH using hydroxide/sulfide solubility curves, choose the right coagulant (aluminum, iron, calcium, lanthanum, or organics), and validate against metals/COD/BOD/phosphorus before scaling. The test bench isn't the finish line; it's the feasibility gate when you're treating 150,000+ gpd.
Lean wastewater: cost center or controllable system?
Commodity choices (lime, alum, ferric) can generate 70–85% more sludge than optimized blends—driving hazardous waste hauling, clogging lines, and shortening pump life. Robin reframes the "penny-per-pound" price war into a total-system economics conversation: sludge recyclability, maintenance cycles, and realistic break-even targets.
PFAS: remove now, plan to destroy
For hex-chrome platers and other industrial dischargers, Robin shares near-term and emerging options: carbon filtration for immediate removal, evaporation/condensation where capital exists, and destruction pathways under evaluation—advanced oxidation, electrochemical oxidation, "thermobotic agglomeration," and ball milling—with an eye on evolving limits and cost realities.
One Water thinking for manufacturers
"Water is water." Robin introduces the One Water mindset for plant leaders: tighten internal loops, reduce community draw and discharge impact, and align non-contact, potable, and wastewater under one stewardship model. It's not a club—it's a decision framework that's already influencing global brands and drought-stressed regions.
Treat each round of testing as a hypothesis check, each chemical as a system lever, and each gallon as a shared resource. That's how leaders turn compliance into predictable results.
Stay engaged, keep learning, and continue scaling up your knowledge!
