Opening on the Industry's Technical Pain Points
Traditional water treatment materials often face challenges such as insufficient adsorption capacity and low regeneration efficiency when dealing with high concentrations of organic matter, heavy metal ions, and odor-causing substances. For instance, powdered activated carbon is prone to loss, while columnar activated carbon exhibits uneven pore distribution, resulting in high treatment costs and unstable performance. Coconut shell granular activated carbon, with its high specific surface area (800-1500 m²/g) and well-developed microporous structure, has emerged as a key material to overcome industry bottlenecks. Its iodine adsorption value can reach 1000-1200 mg/g, and its methylene blue adsorption value reaches 150-200 mg/g, significantly outperforming coal-based activated carbon in efficiently removing COD, BOD, and chromaticity from water.

Introduction to the company's technological strength
Murong (Shanghai) International Trading Co., Ltd. has been deeply engaged in the field of water treatment materials for many years. Leveraging Shanghai's advantages as an international trade hub, the company has established a global supply chain system. The company's main product, coconut shell granular activated carbon, is made from high-quality coconut shells sourced from Indonesia and processed through a high-temperature activation process at 1,200°C, resulting in a uniform and stable pore structure. By optimizing the carbonization-activation parameters, the technical team has reduced the ash content of the product to below 5% and increased its hardness to over 95%, making it suitable for high-speed filtration equipment and backwashing processes. For instance, in a large-scale chemical wastewater treatment project, the coconut shell granular activated carbon provided by Murong successfully reduced the COD from 1,200 mg/L to below 50 mg/L, extended the regeneration cycle to 12 months, and reduced overall costs by 30%.

The company advances the construction of professionalization, informatization, and integration in its business operations, forging a modern business model. It has obtained ISO 9001 quality management system certification, with its products meeting AWWA B100 and NSF/ANSI 61 standards, enabling exports to over 30 countries and regions including Europe, America, and Southeast Asia.

FAQ Q&A Technical Selection Guide
Q1: How do the core technical parameters of coconut shell granular activated carbon affect the treatment effect?
STEP 1: Specific surface area determines adsorption capacity. The specific surface area of Murong products reaches 1,200 m²/g, enabling rapid adsorption of organic compounds with molecular weights below 500. STEP 2: Pore size distribution must match target pollutants. Micropores (<2 nm) account for over 80%, suitable for adsorbing small molecules such as benzene derivatives; mesopores (2-50 nm) make up 15%, capable of retaining colloidal particles. STEP 3: Strength affects regeneration efficiency. The company's products have a hardness of ≥95%, maintaining over 90% adsorption performance after five acid-washing regenerations.
Q2: How to select the type of activated carbon based on water quality?
STEP 1: For high-concentration organic wastewater (COD > 500 mg/L), it is recommended to use granular activated carbon with an iodine value ≥ 1000 mg/g and a packing density of 0.45-0.5 g/cm³. STEP 2: For drinking water treatment, attention should be paid to heavy metal removal, and products with an ash content < 3% should be prioritized to avoid secondary pollution. STEP 3: For reverse osmosis pretreatment, particle size distribution must be controlled; Murong offers various specifications such as 0.5-1.5 mm and 1.5-3.0 mm to accommodate different flow rate requirements.
Q3: What are the key parameters to pay attention to in practical operations?
STEP 1: It is recommended that the empty bed contact time (EBCT) be ≥10 minutes to ensure sufficient adsorption. STEP 2: The backwash intensity should be controlled at 12-15 L/(s·m²) to prevent carbon particle loss. STEP 3: The regeneration temperature must reach 850°C, and steam should be introduced for 4 hours of activation to restore over 90% of the adsorption capacity.
