Nalco 93033 -

Continuous injection via chemical metering pump into the cooling tower basin or the recirculating line downstream of the makeup water inlet. Never slug-dose Nalco 93033, as this can cause localized high phosphate levels leading to calcium phosphate precipitation. Compatibility and Blowdown Considerations Nalco 93033 is compatible with oxidizing biocides (e.g., chlorine, bromine, chlorine dioxide) but care must be taken to avoid simultaneous feed at the same injection point. Nalco recommends feeding the inhibitor separately from biocides, ideally by at least 12 inches of pipe distance or 5 minutes apart in time.

A: No. It is zinc-free and chromium-free, making it safer for discharge and less prone to causing brass dezincification. nalco 93033

A: Use a phosphate test kit (Hach or equivalent) to measure orthophosphate. Multiply the PO₄ reading by a factor (typically 6–10) to estimate product ppm. Confirm factor with your Nalco representative. Continuous injection via chemical metering pump into the
