Activated Clay Series FAQ
Q: What makes your Activated Clay Series different from regular bleaching earth?
A: Our Activated Clay Series undergoes proprietary activation processes that create a more extensive pore structure and optimized surface chemistry. This results in 20-30% higher adsorption capacity compared to conventional bleaching earth, with superior selectivity for removing impurities while preserving desirable components.
Q: How should we store the Activated Clay Series products?
A: Store in original packaging in a dry, well-ventilated area away from moisture and direct sunlight. Optimal storage temperature is between 10°C and 30°C. Once opened, reseal bags tightly or transfer contents to airtight containers. Properly stored, the product maintains full activity for 12 months from manufacturing date.
Q: Can the Activated Clay Series be regenerated after use?
A: Yes, our Premium and Industrial grades can undergo thermal regeneration at 300-350°C for 2-3 hours to restore approximately 70-80% of original activity. However, regeneration isn't recommended for Food Grade due to potential contamination risks. Always conduct small-scale tests before implementing regeneration procedures.
Technical Advantages
- Enhanced Selectivity: Precisely engineered to target specific contaminants
- Reduced Oil Retention: Low adsorption of desirable oils (≤25%)
- Consistent Quality: Rigorous batch-to-batch QC ensures uniform performance
- Flexible Applications: Custom formulations available for specific needs
Application Guidelines
For optimal results with our Activated Clay Series:
- Preheat material to recommended temperature (typically 80-120°C)
- Add clay gradually at 0.5-5% dosage (depending on application)
- Maintain agitation for 15-30 minutes contact time
- Filter through appropriate filtration system
- Monitor results and adjust dosage as needed
Activated Clay Series FAQ (Continued)
Q: What safety precautions should be taken when handling Activated Clay Series products?
A: While our products are generally safe, we recommend using dust masks (NIOSH N95 or equivalent) during large-scale handling to prevent inhalation of fine particles. Wear protective gloves and goggles when handling activated clay in powder form. Ensure adequate ventilation in processing areas and avoid creating dust clouds.
Q: How does temperature affect the performance of Activated Clay Series?
A: Performance typically improves with temperature up to the optimal range (varies by product grade). Generally, every 10°C increase within the recommended range can improve adsorption rates by 15-20%. However, exceeding maximum recommended temperatures may damage the pore structure and reduce effectiveness.
Q: Can Activated Clay Series be used in water treatment applications?
A: Yes, our specially formulated W-series is designed for aqueous systems, effectively removing organic contaminants, heavy metals, and color bodies. Typical dosage ranges from 0.1-2 g/L depending on water quality requirements. Contact our technical team for specific water treatment recommendations.

Activated Clay Series FAQ (Final Section)
Q: What is the typical lead time for Activated Clay Series orders?
A: Standard grades are typically available for immediate shipment (1-3 business days). Custom formulations and large orders (10+ tons) require 2-3 weeks for production. We maintain strategic inventory at multiple locations worldwide to ensure reliable supply.
Q: Do you offer technical support for Activated Clay Series applications?
A: Yes, our team of PhD chemists and process engineers provides comprehensive technical support including laboratory testing, process optimization, and troubleshooting. We can conduct pilot trials at your facility or our technical center to verify performance before full-scale implementation.
Q: How does your Activated Clay Series compare to activated carbon?
A: While both are adsorbents, our clay offers several advantages: typically 30-50% lower cost per unit, higher selectivity for certain contaminants (especially polar compounds), easier filtration due to larger particle size, and often better color removal. Carbon may be preferable for certain VOC removal applications.
