If you want to tailor this information to your specific system, let me know:

Suspended solids like silt, clay, and iron oxides naturally concentrate in cooling towers. Without a dispersant, these particles agglomerate and settle in low-flow zones. Nalco 93033’s polymer coats each particle with a negative charge, causing them to repel each other and remain in the bulk water flow.

Cole's eyes flicked to the vials’ labels. "It's a stabilizer blend. Proprietary. High-value, high-sensitivity." He tapped one of the vials as if acknowledging a rare specimen. "Withholding it from process lines is standard; diversion could cause irreparable contamination."

"Of course." Elias's voice was steady. "Which is why Nalco ships only under strict chain-of-custody protocols. But someone can replicate the formula—it's not magic. Or someone with access can misuse it. We never intended it as a tool for deception."

NALCO 93033 operates primarily as a chemical treatment additive. Its formulation targets the aggressive environment inside heating and cooling loops, working to extend equipment life cycles. NSF Registration and Food Industry Constraints

Maya thought of the little crate she'd found. Had that been a test? A decoy? She asked Elias whether the product could be traced—was there a chemical tracer, isotopic fingerprint, serializing agent? He nodded. "We add a subtle marker—hard to detect with basic lab kits but obvious to our forensic assays. If you can get us samples, we can tell you if it was ours."
