The efficacy of demulsifiers in industrial water treatment hinges on dosing methods, system compatibility, and environmental stability. Key strategies for Chemi Tech demulsifiers include:
1. Precision Dosing and Location
Settling Tanks: Use slow-acting demulsifiers (e.g., high-MW polyethers) for sufficient contact time;
Rapid Separation: Inject fast-acting types (e.g., low-MW quaternary salts) at pipeline mixers or electric dehydrator inlets;
Physical Enhancement: Combine with air flotation or centrifugation to accelerate oil rise and solid settling.
2. Process Synergy
High-Salinity Adaptation: Sulfonated asphalt derivatives maintain efficacy in Cl >5000 mg/L environments;
Sludge Control: Reduce demulsifier dosage to 0.005%-0.02% when compounding with inorganic flocculants (e.g., PAC) to minimize sludge volume.
3. Stability and Cost Efficiency
Temperature Tolerance: Mineral-oil products remain stable at 5°C-50°C without crystallization or degradation;
Storage Management: Emulsion types require mechanical stirring to redisperse settled active components;
Longevity: Modified silicone polyethers provide 24-hour sustained demulsification, reducing dosing frequency by 30%.
Process coordination (e.g., pH adjustment to 6-9 for optimal interfacial activity) and real-time monitoring (e.g., >90% clarified water transmittance) significantly enhance operational efficiency. Feel free to contact via +8619820415595.
