Preventing scale and mineral deposits that interfere with heat transfer. Boiler Feedwater Systems: Protecting metal surfaces from corrosion and deposition. Wastewater Treatment:

: Because it functions as a highly concentrated fluid, smaller volumes achieve higher efficacy, freeing up physical warehouse floor space.

The product uses advanced polymers to prevent the precipitation of minerals like calcium carbonate and calcium sulfate. By keeping these minerals in suspension, it prevents the formation of hard "scale" on heat exchange surfaces.

Operators must wear chemical-resistant gloves, safety goggles, and protective clothing during handling. : Preventing hard scale formation reduces the need

– Install online pH and conductivity controllers. Automate blowdown.

Typically, the product is fed into the system using a . For the best results, it should be applied to a point of high turbulence (like the cooling tower basin near the pump suction) to ensure even distribution throughout the system. Safety and Handling

NALCO 8357 should be stored in a location where the product temperature can be maintained between 20°F (–7°C) and 120°F (49°C) . In cold climates, heat tracing and insulation of exposed containers and transfer lines may be necessary because the product becomes very thick when the ambient temperature reaches 40°F (4°C). A full water analysis is required before implementation

is a liquid, multi-functional water treatment program. It is primarily categorized as an antiscalant and corrosion inhibitor . Unlike single-purpose chemicals, Nalco 8457 is formulated to provide a "total system" approach, meaning it manages several chemical imbalances simultaneously in complex water environments.
