CW-13 Non-Toxic Food Grade Water Decoloring Agent - Readily Biodegradable Cationic Polymer Compatible with Biological Treatment Systems

CW-13 is a low-toxicity modified polyamine-based cationic polymer specifically developed for food processing, beverage, brewery, and dairy industry wastewater treatment. Unlike conventional decolorants, CW-13 is fully compatible with biological treatment systems, showing zero toxicity impact on activated sludge microorganisms (EC50 > 1000 mg/L) and offering readily biodegradable properties.

• Non-toxic to activated sludge microorganisms at operational dosages
• Near-neutral pH formulation minimizes pH adjustment requirements
• Readily biodegradable per OECD 301B testing standards
• FDA compliant for incidental food contact in processing environments
• 70% COD removal without compromising downstream biological treatment

Designed for food and beverage processing facilities: fruit juice and beverage production, brewery and winery wastewater, dairy processing effluent, slaughterhouse wastewater, and food additive manufacturing operations.

Dilute with 10-30 times water and dose directly into the equalization tank or before the primary clarifier. Optimal dosage: 100-400 ppm based on wastewater color and COD. Can be used as a pre-treatment before biological processes or as a polishing step. Works effectively at pH 6-9.

Supplied in food-grade HDPE drums: 30kg, 250kg, and 1250kg IBC. Store at 5-30°C in a dry environment away from direct sunlight. Non-flammable, non-explosive. Shelf life: 12 months under recommended storage conditions.
