Nalco 93033 Portable 〈Original – 2024〉

The primary function of Nalco 93033 is to serve as a powerful disinfectant, leveraging the strong oxidizing properties of chlorine. Its effectiveness stems from its ability to eliminate a broad spectrum of microorganisms, including bacteria, algae, and biofilms, which can plague industrial water systems.

: It acts as a protective agent for cooling water, preventing mineral buildup (scale) and chemical degradation (corrosion) within machine cooling circuits.

First, reduce hexavalent chromium to trivalent (using sodium metabisulfite). Flush system. Passivate with a high initial dose of 93033 (200-300 ppm) for 48 hours, then drop to maintenance levels.

Because industrial water treatments contain concentrated active compounds, operators must reference the official safety parameters outlined by Ecolab Safety Data Sheets (SDS) before handling: nalco 93033 - NSF nalco 93033

provided by Ecolab/Nalco for the specific batch and product before handling. Water treatment chemistry should only be applied by trained professionals who understand the specific metallurgy and operating pressures of the boiler system.

: Can cause moderate irritation. Goggles and face shields are required for handling.

NALCO 93033 is a specialized cooling water additive used for industrial chemical treatment. It is often categorized as a precursor for water treatment systems, such as chlorine dioxide generation. Key Specifications and Storage Shelf Life : One year when stored at a maximum temperature of Storage Group : Classified in The primary function of Nalco 93033 is to

Indirectly. By removing scale and biofilm (which harbor bacteria), it supports biocide efficacy. However, you still need a secondary biocide (e.g., chlorine, DBNPA) specifically for Legionella control.

NALCO 93033 is primarily utilized in systems requiring continuous thermal exchange and strict metallurgical protection.

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.

: Typically added after a system has been cleaned with a biocide and flushed with demineralized water until conductivity falls below 20 µS/cm.

: Typically grouped with alkali or non-hazardous solvents depending on the specific facility protocol, but must be kept closed when not in use to prevent vapor accumulation. Preparation and Application

: Storage areas must be bunded (at 110% of the largest tank capacity) to prevent environmental contamination.
