Nalco 93033 May 2026

Nalco 93033 is compatible with common oxidizing biocides (chlorine, bromine, chlorine dioxide, bleach), but do not feed them simultaneously in the same line. Inject biocides at a separate point, and ideally, at a different time (e.g., shock-dose chlorine at night while Nalco 93033 feeds continuously).

| Feature | Nalco 93033 | Traditional Molybdate | Nitrite-based | |---------|-------------|----------------------|----------------| | Corrosion control | Excellent (Fe & Cu) | Good (Fe only) | Good but toxic | | Scale control | Excellent (CaCO₃, CaPO₄) | Poor | Poor | | Environmental profile | Low aquatic toxicity if neutralized | Moderate (Mo is regulated in some regions) | High toxicity | | Cost per ppm active | Moderate | High | Low (but requires precise control) | nalco 93033

If your system operates at high temperatures (>140°F or 60°C) or low pH (<6.5), Nalco 93033’s performance may degrade—consult with a Nalco representative for those niche applications. Nalco 93033 is compatible with common oxidizing biocides

How does it stack up against generic alternatives? | Feature | Nalco 93033 | Traditional Molybdate

| Feature | Nalco 93033 | Generic Phosphate-Phosphonate | | :--- | :--- | :--- | | Polymer Quality | Proprietary high-molecular-weight acrylic terpolymer | Often a simple homopolymer (less effective at high stress) | | Stability at High Heat | Effective up to 200°F skin temperature | Degrades above 160°F, leading to scale | | Tolerance to Upsets | Margin of error ±30% | Requires precise control | | Technical Support | Included (Nalco field service) | None or limited | | Price | Premium | Lower |

Verdict: For mission-critical systems where a 1% efficiency loss costs thousands of dollars, Nalco 93033 is worth the premium. For low-stress, small towers with perfect water chemistry, a generic may suffice, but you lose the professional support.
