is a highly effective, broad-spectrum, non-oxidizing biocide formulated primarily to control microbial growth, bio-fouling, and microbiological corrosion in industrial cooling water loops and processing systems. Manufactured by Ecolab / Nalco Water , managing this chemical requires strict compliance with its Safety Data Sheet (SDS) due to its corrosive nature and high aquatic toxicity.
: Cooling towers exposed directly to environmental debris.
Used in open and closed-loop cooling systems, process water systems, and brewery pasteurizers. It is copper-free, making it safe for closed-loop systems.
Dosage guidance varies by application, emphasizing the need for professional assessment: nalco 77352 sds
Lena paused. Plant policy was absolute: No SDS, no handling. She sighed, rubbed her eyes, and walked with Marco to the main office terminal. They pulled up the global NALCO database and downloaded the .
: Corrosive to skin surfaces. Can trigger severe, irreversible chemical burns and painful allergic skin sensitization reactions.
Soak up with inert absorbent material (e.g., sand, silica gel, universal binder). Prevent product from entering drains, surface water, or ground water due to its aquatic toxicity. 5. Handling and Storage Requirements (Section 7 of SDS) Safe handling is critical to preventing operator exposure. Used in open and closed-loop cooling systems, process
Personnel must isolate the spill area and prevent the chemical from entering storm drains, natural waterways, or soil channels. Large liquid volume releases should be diked with inert absorbents like sand or clay, pumped into labeled storage recovery drums, and disposed of according to regional hazardous waste regulations.
