Nalco 93033

Nalco 93033 is a liquid cooling water treatment additive primarily used in open recirculating cooling water systems. It is classified as a stabilized phosphate-based corrosion inhibitor combined with a polymer dispersant.

Unlike traditional formulations that rely heavily on heavy metals like chromate or zinc (which pose environmental disposal issues), Nalco 93033 employs a synergistic blend of: nalco 93033

The unique formulation allows for operation at higher cycles of concentration (COC), meaning less blowdown, reduced water consumption, and lower overall operational costs. Nalco 93033 is a liquid cooling water treatment

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. The unique formulation allows for operation at higher

In the world of industrial water treatment, few product codes carry as much weight as Nalco 93033. Manufactured by Ecolab’s Nalco Water division, this specialty chemical is a liquid scale and corrosion inhibitor designed primarily for open recirculating cooling water systems. For facility managers, plant engineers, and water treatment professionals, understanding the precise application, chemistry, and safety protocols for Nalco 93033 is critical to maximizing system efficiency and extending equipment lifespan.

Nalco 93033 is not a general-purpose biocide or a simple pH adjuster. It is a sophisticated, multi-component formulation that targets two of the most destructive forces in cooling towers: mineral scale (calcium carbonate, calcium phosphate) and metallic corrosion (iron, copper, and their alloys).

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).
