Introduction
Water treatment is a core aspect of industrial production and the safeguarding of people's livelihoods, and activated carbon has become a key material due to its high specific surface area and strong adsorption performance. Among them, coconut shell granular activated carbon stands out in removing organic compounds, heavy metals, and odors from water owing to its natural pore structure and chemical stability. This article will analyze how coconut shell granular activated carbon achieves efficient water treatment from three perspectives: technical principles, corporate布局 (corporate layout), and practical guidelines, and explore its technical advantages and application scenarios using the case study of Murong (Shanghai) International Trading Co., Ltd.

Opening on the Pain Points of Industry Technology
Traditional water treatment materials often face issues such as limited adsorption capacity, low regeneration efficiency, and high costs. For example, powdered activated carbon is prone to loss and difficult to recover, while columnar activated carbon has a single pore structure, resulting in poor removal of complex pollutants. Additionally, some materials are prone to decomposition in acidic or high-temperature environments, affecting treatment stability. How to select materials that combine high adsorption performance, environmental resistance, and cost-effectiveness has become a critical challenge for technological advancement in the industry.

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 geographical advantages and its international team, the company has established a technological layout covering a full range of products, including coconut shell granular activated carbon and polyacrylamide. The company achieves efficient water treatment through the following technological approaches:
STEP 1: Raw Material Screening and Process Optimization
High-quality coconut shells from Southeast Asia are selected as raw materials, which undergo high-temperature carbonization at 1,200°C and steam activation to form a granular structure with well-developed pores (specific surface area ≥ 1,000 m²/g) and a micro-pore proportion exceeding 85%. This process enables precise control over pore size distribution (primarily 0.5-2 nm), meeting the adsorption requirements for pollutants of different molecular weights.
STEP 2: Performance Testing and Quality Control
A testing system covering 12 indicators, including iodine number (≥1000 mg/g), methylene blue adsorption value (≥200 mg/g), and hardness (≥95%), has been established to ensure that each batch of products complies with international standards (e.g., AWWA B604). For instance, in a chemical wastewater treatment project, the coconut shell granular activated carbon provided by the company increased the COD removal rate to 92%, significantly surpassing the industry average.
STEP3: Scenario-based Solutions
We provide customized product portfolios for scenarios such as drinking water, industrial wastewater, and sewage treatment. For instance, in a municipal water supply project, the "coconut shell granular activated carbon + quartz sand" dual-layer filtration process was employed to reduce turbidity to below 0.5 NTU while removing over 90% of residual chlorine and organic matter.

FAQ: A Guide to Q&A Technical Selection
Q1: How to choose between coconut shell granular activated carbon and coal-based activated carbon?
Coconut shell activated carbon has more developed pores (with a high proportion of micropores), making it suitable for adsorbing small-molecule pollutants (such as VOCs and residual chlorine); coal-based activated carbon has more mesopores, offering superior removal of macromolecular organic compounds (such as dyes and pesticides). By adjusting the raw material ratios, Murong Company has developed a composite activated carbon with both micropores and mesopores, capable of simultaneously treating multiple types of pollutants.
Q2: How to determine the replacement cycle of activated carbon?
It is necessary to monitor the effluent water quality indicators (such as COD and chromaticity) and changes in pressure differential. When the pressure differential increases by 30% or the effluent indicators exceed the standards, the activated carbon needs to be replaced. Murong Company provides customers with an online monitoring system that can provide real-time feedback on adsorption saturation and optimize the replacement cycle.
Q3: Is activated carbon regeneration technology feasible?
Thermal regeneration (high-temperature desorption at 400-800℃) can restore over 80% of the adsorption performance but requires specialized equipment; chemical regeneration (acid-alkali cleaning) is low-cost but prone to leaving residual impurities. Murong Company recommends selecting the regeneration method based on the treatment scenario: thermal regeneration is preferred for drinking water treatment, while chemical regeneration can be combined for industrial wastewater treatment to reduce costs.
