Water treatment is an essential process in modern industrial operations, environmental protection, and daily life. As global environmental awareness increases and industrial standards become more stringent, the demand for high-quality water treatment materials continues to grow. Murong (Shanghai) International Trading Co., Ltd., located in Shanghai, has established itself as a professional supplier in the international water treatment materials market, offering a comprehensive range of products including industrial activated carbon, polyacrylamide, citric acid, and anthracite filter media.
Understanding Industrial Activated Carbon
Activated carbon is a porous material with a large specific surface area that effectively adsorbs impurities from water. Murong International offers several types of industrial activated carbon:
Types of Activated Carbon Products
- Coconut shell granular activated carbon: Made from high-quality coconut shells, this type features excellent pore structure and adsorption capacity, ideal for drinking water purification and food industry applications.
- Powdered activated carbon: With its fine particle size, it provides rapid adsorption and is commonly used for emergency water treatment and wastewater color removal.
- Columnar activated carbon: This shape offers good mechanical strength and low pressure drop, suitable for gas phase purification and industrial wastewater treatment.
- Spherical activated carbon: Its uniform spherical shape ensures consistent flow characteristics, often used in medical and high-purity water treatment applications.
- Honeycomb activated carbon: Designed for gas phase treatment, it provides large contact area and low pressure loss, ideal for VOCs removal and air purification.
Key Parameters of Activated Carbon
When selecting activated carbon products, several technical parameters are crucial:
| Parameter | Description |
|---|---|
| Iodine Number | Indicates adsorption capacity for small molecules (mg/g) |
| Methylene Blue Adsorption | Measures adsorption capacity for medium-sized molecules (ml/g) |
| Hardness | Reflects mechanical strength and resistance to attrition (%) |
| Ash Content | Indicates inorganic impurity content (%) |
| Particle Size Distribution | Affects flow characteristics and adsorption rate |
Polyacrylamide: The Essential Water Treatment Chemical
Polyacrylamide (PAM) is a crucial flocculant in water treatment processes. Murong International provides both anionic and cationic polyacrylamide products tailored to different applications:
Applications of Polyacrylamide
- Municipal wastewater treatment: Effective for sludge dewatering and suspended solids removal
- Industrial wastewater: Particularly effective for papermaking, textile, and food processing wastewater
- Drinking water treatment: Helps remove turbidity and organic matter
- Oilfield applications: Used in drilling fluid formulation and enhanced oil recovery
Selection Guide for Polyacrylamide
Choosing the right polyacrylamide requires consideration of:
- Ionic type (anionic, cationic, or nonionic)
- Molecular weight (low, medium, or high)
- Degree of hydrolysis (for anionic types)
- Dissolution time and flocculation speed
- Compatibility with system pH and temperature
Citric Acid: More Than Just a Food Additive
While widely known as a food preservative and acidulant, citric acid plays multiple roles in water treatment:
Industrial Applications of Citric Acid
- Water softening: Chelates calcium and magnesium ions to prevent scale formation
- Metal cleaning: Removes rust and oxide layers from metal surfaces
- pH adjustment: Acts as a buffering agent in various industrial processes
- Wastewater treatment: Helps remove heavy metals through chelation
Quality Specifications
Murong International’s citric acid meets international standards with:
- Purity ≥99.5%
- Low heavy metal content (Pb < 5ppm, As < 2ppm)
- Consistent particle size distribution
- Excellent solubility and stability
Anthracite Filter Media: The Foundation of Physical Filtration
As a natural filtration material, anthracite offers several advantages in water treatment systems:
Characteristics of High-Quality Anthracite
- High carbon content: Typically >85% for optimal filtration performance
- Uniform particle size: Ensures consistent flow rates and filtration efficiency
- Mechanical strength: Resists breakdown during backwashing
- Chemical stability: Maintains performance across a wide pH range
Typical Applications
- Multi-media filtration systems (combined with sand and garnet)
- Industrial wastewater pre-treatment
- Drinking water treatment plants
- Groundwater remediation projects

FAQ
What factors should I consider when selecting industrial activated carbon?
Key considerations include the type of contaminants, required removal efficiency, flow rate, system pressure, and budget constraints. Different applications may require specific pore structures or particle sizes for optimal performance.
How do I determine the correct dosage of polyacrylamide?
Dosage depends on water quality parameters like turbidity, suspended solids content, and pH. We recommend conducting jar tests with different concentrations to determine the optimal dosage, typically ranging from 1-10 ppm depending on the application.
Can citric acid replace traditional scale inhibitors?
Citric acid works well for preventing calcium carbonate scale in systems with moderate hardness. For higher hardness levels or complex scaling conditions, specialized scale inhibitors may be more effective. Our technical team can help evaluate the best solution for your specific needs.
What maintenance is required for anthracite filter media?
Regular backwashing is essential to maintain filtration performance. The frequency depends on raw water quality and filtration load, typically ranging from once per day to once per week. Periodic media replacement (every 3-5 years) may be needed depending on operating conditions.
