Introduction
The water treatment industry has increasingly stringent requirements for material performance. With its high specific surface area, strong adsorption capacity, and stability, coconut shell granular activated carbon has become a core material in fields such as industrial wastewater treatment and drinking water purification. This article explores its efficient application pathways from three aspects—technical principles, application scenarios, and key selection criteria—drawing on the trade experience and technological布局 of Murong (Shanghai) International Trading Co., Ltd., to provide actionable technical references for the industry.

Opening Remarks on Industry Technical Pain Points
Traditional water treatment materials often face issues such as insufficient adsorption capacity, short regeneration cycles, and high costs when dealing with high concentrations of organic matter, heavy metal ions, or odor-causing substances. For instance, pollutants like benzene derivatives and pesticide residues in industrial wastewater require materials with rapid adsorption, high selectivity, and acid-base resistance. Meanwhile, drinking water purification imposes stricter demands on material safety and the absence of secondary pollution. Although coconut shell granular activated carbon is widely recognized, the performance of products varies significantly with different particle sizes and pore structures, making the selection of appropriate models based on water quality characteristics a critical challenge in the industry.

Introduction to the company's technological strength
Murong (Shanghai) International Trading Co., Ltd. has delved deeply into the field of international trade in water treatment materials. Leveraging Shanghai's geographical advantages and industry resources, it has established a trading system covering a full range of products, including coconut shell granular activated carbon, powdered activated carbon, and columnar activated carbon. The company's team boasts over 10 years of industry experience and is well-versed in the technological routes and product characteristics of mainstream activated carbon manufacturers worldwide, enabling it to provide customers with full-process services ranging from water quality analysis and material selection to application scheme design.
Technical Layout and Product Advantages
STEP 1: The coconut shell granular activated carbon represented by Murong is made from high-quality coconut shells sourced from Southeast Asia, such as Indonesia and the Philippines, through high-temperature carbonization and activation processes. It has an iodine value of 800-1200 mg/g, a specific surface area of ≥1000 m²/g, and a pore structure primarily composed of micropores, resulting in an adsorption efficiency for small-molecule pollutants (such as benzene and toluene) that is over 30% higher than that of ordinary coal-based activated carbon.
STEP 2: The product's particle size ranges from 0.5 to 8 mm, with specifications customizable based on treatment processes (e.g., fixed bed, fluidized bed). For instance, fine particles measuring 0.5-1 mm are suitable for advanced purification of drinking water, enabling rapid removal of residual chlorine and odors; whereas coarse particles of 4-8 mm are used for industrial wastewater pretreatment, offering strong wear resistance and extending the regeneration cycle to 6-8 times.
STEP3: Murong has established long-term cooperation with multiple ISO 9001-certified factories worldwide, with products passing international certifications such as NSF and FDA, ensuring that indicators like heavy metals and microorganisms meet drinking water safety standards. In 2023, the company provided a customized coconut shell activated carbon solution for a chemical enterprise, reducing the wastewater COD (Chemical Oxygen Demand) from 300 mg/L to below 50 mg/L and lowering operational costs by 25%.

FAQ: Q&A Technical Selection Guide
Q1: How to select the particle size of coconut shell granular activated carbon based on water quality?
A: Particle size selection requires a comprehensive consideration of treatment processes and pollutant characteristics. For fixed-bed processes, it is recommended to use medium particles of 1-4 mm to balance pressure drop and adsorption efficiency; for fluidized-bed processes, coarse particles of 4-8 mm should be selected to reduce the risks of wear and clogging. When treating water containing small-molecule pollutants (such as VOCs), fine particles of 0.5-1 mm are preferred due to their higher proportion of micropores and stronger adsorption selectivity.
Q2: How is the regeneration cycle of coconut shell activated carbon evaluated?
A: The regeneration cycle is influenced by factors such as influent concentration, flow rate, and temperature. Taking industrial wastewater treatment as an example, when the influent COD is ≤200 mg/L, the regeneration cycle of coconut shell activated carbon can reach 6-8 times; if the influent COD is >300 mg/L, the regeneration cycle is shortened to 4-5 times. Murong recommends determining the regeneration threshold through small-scale tests, such as testing effluent indicators after 200 hours of continuous operation. If the COD rebounds by more than 10%, the regeneration process should be initiated.
Q3: What are the performance differences between coconut shell activated carbon and coal-based activated carbon?
A: The iodine value of coconut shell activated carbon (800-1200 mg/g) is significantly higher than that of coal-based activated carbon (400-800 mg/g). With a higher proportion of micropores, its adsorption efficiency for small-molecule pollutants increases by 30%-50%. In contrast, coal-based activated carbon is primarily mesoporous and suitable for treating large-molecule pollutants (such as dyes). Additionally, the ash content of coconut shell activated carbon (≤5%) is lower than that of coal-based activated carbon (≤15%), reducing the risk of secondary pollution.
