INDUSTRIAL MEMORANDUM: PRODUCT STATUS & PROCUREMENT ANALYSIS
Analytical and troubleshooting guidance
If scale forms despite treatment: verify feed rate, check water hardness/saturation indices (Langelier, Ryznar), evaluate make-up water chemistry, and inspect for localized high-temperature zones.
If corrosion is observed: test oxygen levels, pH, corrosive ion concentrations (chloride, sulfate), and metal passivation; assess whether additional corrosion inhibitor or oxygen scavenger is needed.
If foaming or biological growth occurs: check for organic fouling, reduce cycles of concentration, and confirm biocide program effectiveness.
Method 2: Competitive Switch Trial (The "Bait" Strategy)
If you are currently using a competitor’s product (Suez, ChemTreat, Veolia, etc.), Nalco is highly motivated to convert you. Industrial chemical suppliers frequently offer 90 to 120 days of product for free to prove performance superiority. They will even send a technician to manage the transition. nalco 3dt394 free
