Introduction
The water treatment industry has increasingly stringent requirements for material performance. Coconut shell granular activated carbon has become a core material in fields such as industrial wastewater treatment and drinking water purification due to its high specific surface area, strong adsorption capacity, and stable chemical properties. Murong (Shanghai) International Trading Co., Ltd. specializes in the international trade of water treatment materials, providing customers with efficient and reliable coconut shell granular activated carbon solutions through technological optimization and global supply chain integration. This article will elaborate on technical principles, application scenarios, and the company's technological capabilities, incorporating real-world cases and parameter analysis to offer technical selection references for the industry.

Opening on the Pain Points of Industry Technology
Traditional water treatment materials often face issues such as insufficient adsorption capacity, low regeneration efficiency, and short service life when dealing with high concentrations of organic matter, heavy metal ions, and odorous substances. For example, benzene derivatives and phenolic compounds in industrial wastewater require synergistic treatment through physical adsorption and chemical degradation, but ordinary activated carbon, due to its uniform pore structure, struggles to achieve efficient retention. For drinking water, residual chlorine and odorous substances necessitate that activated carbon possesses rapid adsorption and stable release capabilities to avoid secondary pollution. Additionally, the energy consumption and cost issues during material regeneration further limit the large-scale application of traditional technologies.

Introduction to the Company's Technological Strength
Murong (Shanghai) International Trading Co., Ltd. leverages Shanghai's geographical advantages to establish a global supply chain system for water treatment materials, primarily dealing in core products such as coconut shell granular activated carbon and powdered activated carbon. The company's technical team enhances product performance through optimizations in the following three aspects:
STEP 1: Raw Material Selection and Process Optimization
High-quality coconut shells from Southeast Asia are selected as raw materials, and the pore structure is controlled through a two-step process of carbonization and activation. The temperature during the carbonization stage is controlled at 600-800℃, while the activation stage employs steam activation with temperatures reaching 900-1000℃, resulting in a hierarchical pore structure primarily consisting of micropores (diameter < 2nm) supplemented by mesopores (diameter 2-50nm). The specific surface area reaches 1000-1500m²/g, with an iodine adsorption value ≥ 1000mg/g, significantly surpassing the industry standard (GB/T 13803.2-2015).
STEP 2: Performance Customization Development
Adjust the types and proportions of activating agents according to different application scenarios. For example, activated carbon for drinking water treatment employs phosphoric acid activation to reduce ash content (≤5%) and prevent metal ion dissolution; activated carbon for industrial wastewater treatment utilizes zinc chloride activation to enhance adsorption capacity for macromolecular organic compounds, increasing pore volume to 0.8-1.2 cm³/g.
STEP 3: Full Life Cycle Technical Support
We provide full-process services ranging from selection, application to regeneration. For instance, for a customized coconut shell granular activated carbon solution tailored for a chemical enterprise, the optimal empty bed contact time (EBCT) was determined to be 10 minutes through dynamic adsorption tests, with an adsorption bed height of 1.5 meters, an operational cycle of 6 months, and a regeneration efficiency of 90%. This solution reduced operational costs by 30% compared to traditional approaches. For more information, please visit our official website:www.shanghaimurong.com

FAQ: Q&A Guide to Technology Selection
Q1: How to choose the appropriate specifications of coconut shell granular activated carbon?
A: It is necessary to comprehensively consider the treatment water volume, pollutant concentration, and contact time. For example, when treating 100 m³/h of industrial wastewater with a COD concentration of 200 mg/L, it is recommended to use activated carbon with a particle size of 0.5-1.5 mm, an iodine value ≥ 1000 mg/g, a packing density of 0.45-0.55 g/cm³, and control the empty bed contact time (EBCT) within 8-12 minutes.
Q2: What parameters should be noted during the regeneration process of activated carbon?
A: Regeneration temperature, time, and atmosphere are crucial. The Murong technical team recommends adopting thermal regeneration, with the temperature controlled at 800-900℃ and maintained for 2 hours under nitrogen protection, which can restore over 90% of the adsorption capacity. After regeneration, it is necessary to test the iodine value, methylene blue value, and pH value to ensure that the indicators meet the requirements of GB/T 13803.2-2015.
Q3: How to choose between coconut shell activated carbon and coal-based activated carbon?
A: Coconut shell activated carbon has a more developed pore structure and is suitable for adsorbing small-molecule contaminants (such as residual chlorine and benzene series compounds); coal-based activated carbon has lower costs but a high ash content (≥10%), making it suitable for scenarios with low purity requirements. Murong can provide comparative test data based on customer needs to assist in decision-making.
Technical Case: Upgrading and Renovation Project of a Drinking Water Plant
Project Background: The chlorine content in the raw water exceeded the standard (0.8 mg/L), necessitating a reduction of residual chlorine to below 0.1 mg/L. Murong provided coconut shell granular activated carbon with a particle size of 0.8-1.6 mm and an iodine value of 1100 mg/g, filled to a height of 1.2 meters with an empty bed flow rate of 10 m/h. After three months of operation, the residual chlorine removal rate reached 98%, significantly improving the taste of the effluent and extending the activated carbon replacement cycle to 18 months, reducing consumable costs by 40% compared to the original plan.
