Opening Remarks on Industry Technical Pain Points
Traditional water treatment materials often face issues such as insufficient adsorption capacity and short regeneration cycles when dealing with high concentrations of organic pollutants and heavy metal ions. For example, while powdered activated carbon offers rapid adsorption rates, it is prone to loss and difficult to regenerate; columnar activated carbon has uneven pore distribution, resulting in low adsorption efficiency for small-molecule pollutants. Additionally, some materials exhibit poor stability in acidic or alkaline environments, leading to fluctuations in treatment effectiveness. The industry urgently requires a material that combines high adsorption capacity, long service life, and stable chemical properties to meet purification needs under complex water quality conditions.

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 international resources, it has established a complete industrial chain covering raw material procurement, technical testing, and application support. The company's main product, coconut shell granular activated carbon, is made from high-quality coconut shells sourced from Southeast Asia. Through high-temperature steam activation processes, it forms a well-developed microporous structure, achieving an iodine adsorption value of 1000-1200 mg/g and a specific surface area exceeding 1000 m²/g, significantly surpassing the industry average.

The technical team has endowed the product with both rapid adsorption and high-capacity characteristics by optimizing particle size (0.5-3mm) and pore distribution. For instance, in industrial wastewater treatment projects, Murong's coconut shell granular activated carbon can achieve a COD removal rate exceeding 90% and a heavy metal ion adsorption capacity of over 50mg/g. The company has also established a stringent quality control system, with each batch of products passing ISO 9001 certification to ensure stable performance.


Murong's technological layout focuses on three key directions: First, deepening cooperation with raw material suppliers in Southeast Asia to ensure the purity and sustainability of raw materials; second, collaborating with universities to develop new activation processes and enhance directional pore development capabilities; third, establishing an application database to provide customized solutions based on different water quality conditions. For instance, for drinking water treatment scenarios, the company has developed a dedicated model with low ash content and high mechanical strength, effectively reducing the risk of powder shedding.

FAQ: A Q&A Guide to Technology Selection
Q1: How do the core technical parameters of coconut shell granular activated carbon affect its application effectiveness?
STEP 1: Pore structure is crucial. By controlling the activation temperature (800-950℃) and time (2-4 hours), Murong products form a hierarchical pore structure dominated by micropores (diameter < 2nm) with the inclusion of mesopores (2-50nm). Micropores are responsible for adsorbing small-molecule pollutants (such as benzene series compounds and chlorinated hydrocarbons), while mesopores enhance the adsorption efficiency of large-molecule organic matter (such as humic acid).
STEP 2: Particle size distribution affects flow rate and contact time. Murong offers three specifications: 0.5-1mm, 1-2mm, and 2-3mm. Among them, the 1-2mm model can achieve a flow rate of 0.5-1.5 m/h and a contact time of 15-30 minutes in a fixed-bed reactor, balancing treatment efficiency and pressure drop.
STEP 3: Mechanical strength determines service life. Murong's products significantly outperform industry standards in ball milling hardness (≥95%) and wear resistance rate (≤0.1%) by optimizing the molding process, reducing breakage and dust generation during use.

Q2: How to select the type of activated carbon based on water quality conditions?
STEP 1: Detect water quality indicators, including COD, BOD, heavy metal ion concentration, pH value, etc. For example, high-concentration organic wastewater (COD > 500 mg/L) requires the selection of a high-capacity model with an iodine adsorption value ≥ 1100 mg/g; acidic wastewater (pH < 4) necessitates the choice of acid-resistant products with an ash content ≤ 5%.
STEP 2: Determine the treatment process. Murong provides compatible models for different processes such as fixed bed, fluidized bed, and stirred tank. For instance, the fixed bed process requires products with uniform particle size and low pressure drop to reduce backwashing frequency; the fluidized bed process necessitates models with high mechanical strength to withstand the impact of high-velocity water flow.
STEP 3: Refer to successful cases. Murong has accumulated a wealth of application data in industries such as electronics, chemicals, and pharmaceuticals. For instance, in a wastewater treatment project of a semiconductor enterprise, by selecting Murong's 1-2mm coconut shell granular activated carbon, a fluoride ion removal rate of 92% was achieved under conditions of a flow rate of 1m/h and a contact time of 20 minutes, with annual operating costs reduced by 30%.


Q3: How to control the regeneration cycle and cost of activated carbon?
STEP 1: The regeneration cycle depends on the influent water quality and load. Murong recommends establishing a regeneration model based on actual operational data, such as initiating regeneration when the effluent COD exceeds 30% of the initial value. The regeneration cycle for high-capacity models can reach 6-12 months, while for low-capacity models, it is 3-6 months.
STEP 2: Selection of regeneration process. Murong offers two options: thermal regeneration and chemical regeneration. Thermal regeneration is suitable for most organic pollutants, achieving a regeneration efficiency of over 90%, but with relatively high energy consumption. Chemical regeneration targets specific pollutants (such as heavy metals), enabling in-depth regeneration through acid or alkaline washing, with lower costs but requiring waste liquid treatment.
STEP 3: Cost Optimization Strategy. Murong controls regeneration costs at 40-60% of the price of new carbon through large-scale procurement and process optimization. For example, a chemical enterprise reduced its annual activated carbon procurement costs by 55% and cut waste disposal expenses by adopting Murong's regeneration services.
