Introduction
With increasingly stringent industrial wastewater discharge standards, the technical performance of water treatment materials has become a core factor determining treatment effectiveness. Coconut shell granular activated carbon, with its high specific surface area, strong adsorption capacity, and regenerability, has become the preferred material in the field of industrial water treatment. Munrong (Shanghai) International Trade Co., Ltd., leveraging its extensive industry experience and professional expertise, provides high-performance coconut shell granular activated carbon solutions to clients worldwide. This article will analyze how Munrong achieves efficient water treatment through technological innovation from three aspects: technical principles, corporate strength, and application cases.

Opening on the Pain Points of Industry Technology
In industrial wastewater treatment, traditional adsorption materials often face two major pain points: first, their limited adsorption capacity necessitates frequent replacement, leading to high costs; second, their low regeneration efficiency poses a significant risk of secondary pollution. For example, a chemical enterprise once used coal-based activated carbon to treat benzene-containing wastewater, but due to difficulties in regeneration after adsorption saturation, the annual replacement cost exceeded 2 million yuan, and secondary pollution was generated during the disposal of spent carbon. Although coconut shell granular activated carbon has theoretical advantages, its actual performance is significantly influenced by raw material purity, pore structure, and particle size distribution, and the following key issues must be addressed for practical application:
STEP 1: Raw Material Selection: High-density coconut shells must be used to ensure well-developed pores after carbonization;
STEP 2: Pore regulation: Accurately control the proportion of micropores and mesopores through physical activation methods (e.g., steam activation);
STEP 3: Particle size optimization: Customize particle size (0.5-3 mm) based on the processing scenario (e.g., fixed bed or fluidized bed) to balance pressure drop and adsorption rate.

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 advantage spanning from raw material procurement to technical services:
STEP 1: Raw Material Control: Establish long-term cooperation with high-quality coconut shell suppliers in Southeast Asia to ensure that the iodine value of raw materials is ≥1000 mg/g and the ash content is ≤5%;
STEP 2: Process Innovation: Adopt the "two-stage activation method," initially carbonizing at low temperature (600°C) to retain volatile components, followed by high-temperature (900°C) steam activation for pore expansion, resulting in a specific surface area of the product reaching 1200-1500 m²/g, significantly surpassing the industry average (800-1000 m²/g);
STEP 3: Particle Size Customization: Equipped with German-imported screening equipment, we can provide products with any particle size within the range of 0.5-3mm according to customer requirements, with a standard deviation of particle size distribution ≤0.2mm;
STEP 4: Application Support: Establish a technical team composed of experts in chemical engineering and environmental science to provide full-process services ranging from model selection to operation and maintenance.
Typical Case: In a wastewater treatment project containing heavy metals at an electronics factory, the original use of powdered activated carbon led to system shutdown due to excessively high pressure drop. The Murong technical team recommended using 1.5mm coconut shell granular activated carbon, which maintained a heavy metal removal rate of over 95% while reducing the system pressure drop by 40%, extending the operational cycle to six months, and saving 1.2 million yuan in annual costs.

FAQ Q&A Technical Selection Guide
Q1: How to choose the appropriate particle size of coconut shell granular activated carbon?
A: Particle size selection requires a comprehensive consideration of treatment processes and target pollutants:
- Fixed-bed process: Prioritize particle sizes of 1.0-2.0 mm, balancing pressure drop (typically ≤0.5 MPa/m) with adsorption rate;
- Fluidized bed process: Fine particles with a diameter of 0.5-1.0 mm are selected to improve contact efficiency, but the backwashing frequency needs to be increased;
- High-viscosity wastewater: It is recommended to use a coarse particle size of 2.0-3.0 mm to prevent clogging.
Q2: How is the regeneration cycle of coconut shell granular activated carbon determined?
A: The regeneration cycle depends on the concentration of pollutants in the influent and the adsorption capacity:
- Benzene series compounds treatment: Regeneration is required when the effluent concentration reaches 10% of the influent concentration;
- Heavy metal treatment: Taking copper ions as an example, regeneration is required when the slope of the breakthrough curve is ≥ 0.5 mg/(L·h);
- After testing, Murong's product can achieve a regeneration cycle of 6 to 12 months in conventional industrial wastewater scenarios.
Q3: How to evaluate the adsorption performance of activated carbon?
A: The key detection indicators include:
- Iodine value: Reflects the quantity of micropores; a value ≥1000 mg/g indicates high quality;
- Methylene blue value: measures mesopore capacity, with ≥150 mg/g being preferable;
- Strength: ≥90%, ensuring resistance to pulverization during transportation and use;
- Ash content: ≤5%, reducing interference from inorganic impurities.
