Applications
1. Drinking Water Treatment Coagulant: Dosed in municipal and industrial water plants to destabilize suspended solids and form dense fast settling flocs, removing turbidity, colour, total organic carbon, phosphate, fluoride and heavy metals, while consuming less alkalinity and generating less sludge than traditional alum.
2. Industrial Wastewater Clarification: Applied to textile dyeing, papermaking, electroplating, brewery and food processing effluents to cut chemical oxygen demand, colour and phosphorus, and to condition sludge before dewatering, working reliably over a wide pH and temperature range.
3. Paper And Pulp Wet End Additive: Acts as a strongly cationic polymer in papermaking wet end systems, neutralizing anionic trash and improving retention of fibre fines and mineral fillers, supporting rosin sizing and cleaner sheet formation with lower additive consumption.
4. Antiperspirant And Personal Care Active: Supplied in cosmetic grade quality for roll-on, stick and cream antiperspirant formulations, where it forms a gel plug at the sweat duct opening to reduce perspiration, and also serves as an astringent in underarm care products.
5. Oilfield And Process Water Clarification: Used to coagulate hypersaline produced water and flowback fluids in oil and gas operations, breaking stable emulsions and reducing turbidity ahead of dissolved air flotation, sedimentation or filtration, supporting water reuse and disposal compliance.
