Core Product Range for Industrial Applications
Our specialized product lineup addresses the most demanding industrial water treatment challenges with proven effectiveness:
1. Premium Activated Carbon Solutions
As a leading industrial activated carbon supplier, we offer four specialized formulations:
- Coconut Shell Granular Activated Carbon: Ideal for potable water treatment and food-grade applications due to its high purity and excellent adsorption capacity
- Powdered Activated Carbon: Engineered for rapid adsorption in emergency spill response and color removal applications
- Columnar Activated Carbon: Designed for gas phase filtration with low pressure drop and high mechanical strength
- Honeycomb Activated Carbon: Specialized for VOC removal in industrial exhaust systems with high surface area and uniform airflow
All our activated carbon products comply with ASTM, AWWA, and NSF standards, with iodine numbers ranging from 800 to 1200 mg/g depending on the application requirements. Our technical team provides detailed adsorption isotherm reports to help customers select the optimal product for their specific needs.
2. Polyacrylamide for Advanced Water Treatment
Our polyacrylamide (PAM) products represent the cutting edge in flocculation technology:
- Anionic PAM: Effective for suspended solids removal in industrial wastewater with negative charge characteristics
- Cationic PAM: Specialized for sludge dewatering and organic matter removal with positive charge functionality
- Nonionic PAM: Ideal for neutral pH applications requiring minimal ionic interference
With molecular weights ranging from 8 to 22 million and charge densities from 5% to 60%, our PAM formulations offer precise control over floc size and settling velocity. We provide comprehensive application guidance including dosage optimization and mixing protocol development.
3. High-Purity Citric Acid Solutions
Our food-grade citric acid anhydrous meets FCC, BP, and EP standards with 99.5% minimum purity:
- Water Treatment: Effective pH adjuster and complexing agent for heavy metal removal
- Industrial Cleaning: Natural chelating agent for boiler scale prevention and equipment descaling
- Pharmaceutical: Approved for use in oral formulations and cosmetic products
Available in 25kg bags or bulk containers, our citric acid maintains consistent particle size distribution for optimal dissolution rates. We provide batch-specific certificates of analysis including heavy metal content and microbial testing results.
4. Premium Anthracite Filter Media
Our anthracite filter media offers superior performance for multi-media filtration systems:
- Size Range: 0.6-1.2mm, 0.8-1.6mm, and 1.0-2.0mm standard grades
- Density: 1.45-1.65g/cm³ for optimal backwash efficiency
- Hardness: 3.5-4.0 on Mohs scale for long service life
Sourced from premium coal seams and processed through multiple washing and screening stages, our anthracite media demonstrates consistent quality with less than 2% undersize particles. Each shipment includes sieve analysis reports and specific gravity testing results.
| Product Parameter | Industrial Specification | Quality Standard |
|---|---|---|
| Activated Carbon Iodine Number | 800-1200 mg/g | ASTM D4607 |
| Polyacrylamide Molecular Weight | 8-22 million | ISO 13933 |
| Citric Acid Purity | ≥99.5% | FCC VII |
| Anthracite Uniformity Coefficient | ≤1.5 | AWWA B100 |

Logistics Optimization: With strategic warehouse locations in Shanghai, Tianjin, and Qingdao, we ensure timely delivery to major ports worldwide. Our logistics team handles all customs documentation and coordinates with freight forwarders to minimize transit times.
Sustainability Initiatives: We prioritize eco-friendly packaging solutions and work with suppliers who implement responsible mining practices. Our carbon footprint tracking system helps customers meet their sustainability reporting requirements.
FAQ
What factors determine the right activated carbon for my application?
Selection depends on three primary factors: the contaminant type (organic, inorganic, or gas), concentration levels, and required contact time. Our technical team evaluates these parameters along with your system specifications to recommend the optimal pore structure and particle size distribution.
How does polyacrylamide dosage affect treatment efficiency?
Proper dosage requires balancing floc formation with residual monomer concerns. We recommend jar testing to determine the minimum effective dose, typically ranging from 0.1-5 ppm depending on raw water characteristics. Overdosing can cause system upsets and increase operational costs.
What shelf life can I expect from your citric acid?
When stored in cool, dry conditions below 30°C and 70% RH, our citric acid maintains full potency for 36 months from production date. We recommend rotating stock using the FIFO method and avoiding prolonged exposure to direct sunlight or moisture.
How often should anthracite filter media be replaced?
Replacement frequency depends on raw water quality and loading rates. Under normal conditions, our anthracite media lasts 3-5 years before requiring partial replacement. We recommend annual sieve analysis to monitor media degradation and determine optimal replacement schedules.
