Why Choose Our Walnut Shell Activated Carbon?
Superior Safety Standards
Your water quality concerns end here. Our triple-wash process with deionized water keeps lead content below 0.3 ppm—exceeding GB 5749-2022 requirements. Every batch undergoes 121°C vacuum sterilization, maintaining bacterial counts under 30 CFU/g.
You can trust this material for direct drinking water applications.
Exceptional Odor Removal
Dealing with earthy or musty taste issues? Our Walnut Shell Activated Carbon removes over 95% of Geosmin and 2-MIB compounds. The optimized mesopore structure targets these stubborn odor molecules effectively.
Your customers will notice the difference immediately—clean, sweet-tasting water every time.
Outstanding Mechanical Properties
High hardness (≥95%) means minimal dust generation during handling and operation. You'll experience:
- Extended filter bed life
- Reduced backwash frequency
- Lower operational costs
- Consistent flow rates
The 8–30 mesh sizing maintains pressure drop below 500 Pa, protecting your equipment and reducing energy consumption.

Frequently Asked Questions
Q: How does this item guarantee security for drinking water contact?
A: We execute strict filtering control through our restrictive triple-wash prepare. Lead remains underneath 0.3 ppm, completely complying with GB 5749-2022 and WHO benchmarks. Furthermore, 121°C vacuum sterilization keeps bacterial checks beneath 30 CFU/g, avoiding auxiliary defilement in your systems.
Q: Can it successfully expel hearty or smelly odors like Geosmin and 2-MIB?
A: Completely. With over 1,000 m²/g surface range and a mesopore proportion surpassing 40%, our item accomplishes 95%+ expulsion of these adamant odor compounds. It's particularly built for Ozone-GAC channels and private purifiers, conveying sweet-tasting, odorless water consistently.
Q: What are the financial benefits compared to imported brands?
A: You'll reduce costs by approximately 30% while maintaining premium performance. Our localized pricing of 10,000–14,000 RMB/ton significantly cuts procurement budgets. The high adsorption capacity and low pressure drop (<500 Pa) also reduce backwash frequency and extend filter bed life, lowering your total cost of ownership.
Q: What delivery options are available?
A: Standard orders ship within 7–15 days. Customized solutions require 15–30 days. For urgent projects, we offer 3-day expedited service. We maintain tens of thousands of tons in stock for immediate availability.
Q: Do you provide technical support?
A: Yes. Our team offers pre-sales solution design, on-site assessment, and product selection guidance. After purchase, you receive technical training, 24/7 engineering support, and free replacement for non-human damage within the warranty period.
