Main Product Categories and Technical Specifications
Murong’s product portfolio addresses the complete spectrum of water treatment needs through four primary categories:
1. Industrial Activated Carbon Solutions
As a specialized activated carbon supplier, Murong offers five main types tailored to different applications:
- Coconut Shell Granular Activated Carbon: High iodine value (900-1100mg/g) and large surface area make this ideal for drinking water purification, food industry decolorization, and solvent recovery
- Powdered Activated Carbon: Fine particle size (200-325 mesh) enables rapid adsorption for emergency water treatment, pharmaceutical purification, and chemical intermediate processing
- Columnar Activated Carbon: Mechanical strength >90% ensures durability in fixed-bed reactors for industrial wastewater treatment and gas phase purification
- Spherical Activated Carbon: Uniform 0.5-3mm diameter particles provide consistent flow characteristics for specialized applications like blood purification and catalyst carriers
- Honeycomb Activated Carbon: Unique channel structure offers low pressure drop and high geometric surface area for VOCs abatement in exhaust gas treatment systems
2. Polyacrylamide (PAM) Flocculation Agents
Murong supplies both anionic and cationic polyacrylamide with molecular weights ranging from 8-22 million, catering to different water treatment scenarios:
- Anionic PAM: Effective for suspended solids removal in municipal wastewater and paper mill effluent
- Cationic PAM: Specialized for organic sludge dewatering in food processing and petrochemical industries
- Nonionic PAM: Used in mineral processing and acid-containing wastewater treatment
The company’s PAM products demonstrate excellent solubility and flocculation efficiency, with typical dosage rates of 5-50ppm depending on water quality parameters.
3. Citric Acid Monohydrate
Produced through fermentation process, Murong’s food-grade citric acid meets USP/BP/EP standards with 99.5% minimum purity. Key applications include:
- pH adjustment in water treatment systems
- Chelating agent for heavy metal removal
- Preservative in food and beverage industry
- Buffering agent in pharmaceutical formulations
4. Anthracite Filter Media
The company’s anthracite coal filter media features:
- Size range: 0.6-1.2mm, 0.8-1.6mm, 1-2mm customizable
- Density: 1.4-1.6g/cm³ for optimal backwash performance
- Hardness: >85% for long service life in rapid sand filters
- Acid solubility: <3% ensuring chemical stability
This media is widely used in multi-media filtration systems for removing suspended solids, organic matter, and colloidal particles in drinking water and industrial process water treatment.
| Product Parameter | Typical Value | Application Impact |
|---|---|---|
| Activated Carbon Iodine Value | 900-1100mg/g | Higher value indicates better organic removal capacity |
| Polyacrylamide Molecular Weight | 8-22 million | Affects floc size and settling velocity |
| Citric Acid Purity | ≥99.5% | Ensures minimal impurities in water treatment |
| Anthracite Uniformity Coefficient | ≤1.5 | Affects filtration efficiency and head loss |
Quality Control and Certification System
Murong implements stringent quality management throughout the production process:
- Raw Material Inspection: All incoming materials undergo chemical composition analysis and physical property testing before acceptance
- Production Monitoring: Real-time parameter control in activation furnaces, reaction vessels, and drying systems
- Finished Product Testing: Each batch is tested for key indicators including particle size distribution, moisture content, and adsorption capacity
- Certification Compliance: Products meet ISO 9001:2015, SGS, and REACH requirements, with food-grade products holding HALAL and Kosher certifications
The company’s laboratory is equipped with advanced analytical instruments including BET surface area analyzers, particle size analyzers, and ion chromatography systems to ensure precise quality control.
Industry Application Solutions
Murong’s technical team develops customized solutions for different industrial sectors:
Municipal Water Treatment
For drinking water plants, the company recommends a combination of coconut shell activated carbon for pre-treatment and anthracite-sand multi-media filters for final polishing. This approach effectively removes chlorine, organic compounds, and suspended solids while maintaining stable operation under varying flow conditions.
Industrial Wastewater Management
In textile dyeing wastewater treatment, Murong provides a three-stage process:
- Coagulation-flocculation using cationic polyacrylamide
- Adsorption with powdered activated carbon for color removal
- pH adjustment with citric acid before biological treatment
This comprehensive approach helps clients achieve discharge standards while minimizing chemical consumption.
Food and Beverage Industry
For juice clarification applications, Murong’s powdered activated carbon demonstrates superior decolorization performance compared to traditional diatomaceous earth filters. The product’s high purity and low ash content prevent quality degradation in the final product.
FAQ
What factors should be considered when selecting activated carbon for water treatment?
Key considerations include the type of contaminants (organic compounds, heavy metals, chlorine), required removal efficiency, flow rate, and system design. Coconut shell activated carbon generally offers the best balance of adsorption capacity and mechanical strength for most water treatment applications.
How does polyacrylamide dosage affect flocculation performance?
Optimal dosage depends on water quality parameters like turbidity, pH, and temperature. Under-dosing results in incomplete floc formation, while over-dosing can cause colloidal re-stabilization. Murong provides free jar testing services to determine the ideal dosage for specific applications.
What is the shelf life of citric acid monohydrate?
When stored in cool, dry conditions (below 25°C and relative humidity <60%), the product maintains stability for 24 months from production date. Proper packaging in moisture-proof bags is essential to prevent caking.
How often should anthracite filter media be replaced?
Replacement frequency depends on raw water quality and loading rate. Typically, the media requires replacement every 3-5 years in municipal water treatment applications. Regular backwashing and air scouring can extend service life by preventing channeling and compaction.
