Introduction to Industry Technical Pain Points
Traditional water treatment materials often face issues such as limited adsorption capacity, low regeneration efficiency, and single application scenarios. For example, powdered activated carbon is prone to loss and difficult to recover, while columnar activated carbon has uneven pore distribution, resulting in poor adsorption selectivity. Additionally, when treating high-concentration organic pollutants, some materials encounter technical bottlenecks like rapid saturation and short regeneration cycles, directly affecting treatment costs and the stability of results. Coconut shell granular activated carbon effectively addresses these pain points by optimizing pore structure and surface chemical properties. Its micropores account for over 85%, with a specific surface area reaching 1200-1500 m²/g, enabling efficient adsorption of organic compounds with molecular weights of 500-3000. It also possesses excellent mechanical strength (hardness ≥ 90%), allowing it to withstand water flow impact and backwashing operations, thereby extending its service life.

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, establishing a full-chain technological system covering raw material procurement, production and processing, and quality inspection. The company's main product, coconut shell granular activated carbon, uses high-quality coconut shells from Indonesia as raw materials and undergoes a 1,200°C high-temperature steam activation process, resulting in a uniform and well-developed pore structure. Its iodine adsorption value can reach 1,000-1,200 mg/g, and its methylene blue adsorption value reaches 180-220 mg/g, with performance indicators surpassing industry standards. By optimizing the activation time and temperature profile, the technical team has controlled the product's ash content to ≤5% and moisture content to ≤8%, ensuring stable adsorption performance in both acidic (pH 2-10) and alkaline (pH 8-14) environments.

In terms of applied technology layout, Murong International has developed customized solutions for different water treatment scenarios. For instance, for industrial wastewater treatment, it provides coarse-grained activated carbon with a particle size of 1.5-3.0 mm to reduce water flow resistance; for advanced purification of drinking water, it offers fine-grained activated carbon with a particle size of 0.5-1.0 mm to enhance adsorption efficiency. The company has also established a dynamic adsorption model, verified through laboratory-scale and pilot-scale tests, to accurately calculate material usage and replacement cycles for clients, thereby reducing operational costs.

FAQ: A Q&A Guide to Technical Selection
Q1: What are the core technical parameters of coconut shell granular activated carbon? How to select it based on different scenarios?
STEP 1: Clarify the treatment objectives. If the goal is to remove chromaticity and odor, prioritize products with a methylene blue adsorption value ≥ 200 mg/g; if treating high-concentration organic compounds, focus on the iodine adsorption value (≥ 1000 mg/g) and pore volume (≥ 0.9 cm³/g).
STEP 2: Match particle size specifications. Fine particles of 0.5-1.0 mm are recommended for drinking water treatment, coarse particles of 1.5-3.0 mm for industrial wastewater treatment, and extra-large particles of 3-5 mm for gas-phase adsorption.
STEP 3: Verify the regeneration performance. High-quality coconut shell activated carbon can undergo 5-8 cycles of high-temperature steam regeneration, with an adsorption capacity attenuation rate ≤15%, resulting in lower long-term usage costs.

Q2: How does Murong International's coconut shell activated carbon perform in actual projects?
Taking a wastewater treatment project in a certain chemical industrial park as an example, the raw water COD concentration reached 800 mg/L. By using Murong International's coconut shell activated carbon with a particle size of 2.0 mm, a packing height of 1.5 m, and an empty bed contact time of 15 minutes, the effluent COD was reduced to below 50 mg/L, achieving a removal rate of 93.7%. After six months of operation, following high-temperature regeneration treatment, the adsorption capacity recovered to 92% of its initial value, significantly outperforming similar products.

Q3: How to avoid common issues in the use of activated carbon?
Notes:
- Avoid direct contact with strong oxidizing agents to prevent damage to the pore structure;
- Regular backwashing (flow rate of 8-12 m/h) to prevent clogging;
- Store with humidity ≤ 60% to prevent moisture absorption and caking.
