How does water chemistry influence emulsification efficiency and long-term stability of bitumen water emulsion?
Water chemistry strongly controls emulsifier performance and emulsion stability. High hardness can reduce surfactant effectiveness and increase flocculation risk. High alkalinity or contaminants can shift pH, causing premature breaking or poor storage stability, especially in cationic emulsions. Chlorides and dissolved salts influence conductivity and can alter particle charge behavior. Industrial plants often treat water with softening or filtration and maintain strict pH control so the emulsifier system consistently produces stable droplets with predictable breaking characteristics in the field.
