Industrial Applications
Water Treatment & Remediation
In-situ chemical oxidation (ISCO) for groundwater and soil remediation — sodium percarbonate releases hydrogen peroxide on contact with water, oxidizing chlorinated solvents, petroleum hydrocarbons, and other organic contaminants. Also used for lake and pond restoration to reduce BOD and algae.
Industrial Cleaning & Bleaching
Oxygen-based bleaching agent for pulp and paper, textiles, and laundry operations. Releases active oxygen in solution to remove stains and brighten surfaces without chlorine. Preferred for color-safe bleaching and environmentally sensitive applications.
Disinfection & Sanitization
Broad-spectrum oxidizing disinfectant for food processing equipment, hard surfaces, and agricultural applications. Effective against bacteria, fungi, and biofilm. Breaks down to sodium carbonate and water — no halogenated residuals.
Oilfield & Produced Water Treatment
Oxidizing biocide and H₂S scavenger for oilfield water systems. Sodium percarbonate controls sulfate-reducing bacteria (SRB), eliminates hydrogen sulfide odor, and reduces iron fouling in produced water handling systems.
Pulp & Paper Processing
Peroxide bleaching stage in ECF (elemental chlorine-free) and TCF (totally chlorine-free) pulp bleaching sequences. Provides controlled hydrogen peroxide release for brightness development without damaging fiber.
Aquaculture & Pond Management
Oxygenation and disinfection of aquaculture ponds, fish hatcheries, and recreational water bodies. Sodium percarbonate raises dissolved oxygen levels and controls pathogenic bacteria without leaving harmful residues.
