Opening on the Industry's Technological 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, and odorous substances. For example, benzene derivatives and phenolic compounds in industrial wastewater require rapid removal using high-efficiency adsorption materials, yet ordinary activated carbon, with its simple pore structure, struggles to meet the demands of complex water quality treatment. Additionally, powdered activated carbon is prone to causing secondary pollution, while granular activated carbon poses challenges in flow rate control, both of which constrain the efficiency and stability of water treatment. The industry urgently requires a material that combines high adsorption performance, ease of operation, and long service life to reduce overall treatment costs.

Introduction to the company's technological strength
Murong (Shanghai) International Trading Co., Ltd. has delved deeply into the field of water treatment materials, leveraging Shanghai's geographical advantages and a global supply chain to establish a product matrix centered around coconut shell granular activated carbon. The company's technical team optimizes material performance through the following steps:
STEP 1: Raw Material Selection and Pretreatment
High-quality coconut shells from Southeast Asia are selected, and their pore structures are controlled through a two-step process of carbonization and activation. The carbonization temperature is strictly maintained at 600-700℃, and the activation time is precisely set at 2-3 hours, ensuring an iodine adsorption value of ≥1000mg/g and a methylene blue adsorption value of ≥200mg/g, reaching industry-leading standards.
STEP 2: Optimization of granulation process
By employing an integrated crushing-screening-molding technology, the diameter of activated carbon particles is controlled within the range of 0.5-3mm, balancing flow rate and adsorption efficiency. Measured data shows that at a flow rate of 20m/h, the removal rate of COD can still remain above 85%, representing a 15% improvement over traditional columnar activated carbon.
STEP 3: Breakthrough in Regeneration Technology
The high-temperature steam regeneration process has been developed, shortening the regeneration cycle to 48 hours and achieving a recovery rate of adsorption capacity after regeneration of ≥90%, significantly reducing customers' operational costs. Currently, this technology has been applied to a wastewater treatment project in a chemical industrial park, with an annual treatment capacity of 500,000 tons and a 20% reduction in treatment cost per ton of water.
The company has served over 300 customers globally, with its products certified by the ISO9001 quality management system and exported to regions such as the EU and Southeast Asia, while its technical expertise has been widely recognized in the industry.

FAQ Q&A Technical Selection Guide
Q1: How to select the specifications of activated carbon based on water quality?
A: For high-concentration organic wastewater (such as printing and dyeing, chemical wastewater), it is recommended to use 0.5-1mm fine granular activated carbon to increase the contact area; for low-concentration municipal sewage, 1-3mm coarse granular activated carbon can be selected to balance flow rate and cost. Murong offers customized services for five specifications, suitable for a wide range of operating conditions with a pH of 4-10 and a temperature of 5-50℃.
Q2: What are the core differences between coconut shell charcoal and coal-based charcoal?
A: Coconut shell charcoal has a specific surface area of 1,200-1,500 m²/g, which is 1.5 times that of coal-based charcoal, with micropores accounting for over 80%, enabling higher adsorption efficiency for small-molecule pollutants (e.g., benzene, chloroform). Actual measurements indicate that, under the same dosage, the adsorption capacity of coconut shell charcoal for heavy metal ions is 30% higher than that of coal-based charcoal.
Q3: What parameters should be noted during the regeneration process?
A: The regeneration temperature must be controlled between 800-900°C to prevent the collapse of pore structures, while the steam pressure should be maintained at 0.2-0.3 MPa to ensure full penetration of the regenerant. Murong offers regeneration equipment rental services equipped with an intelligent control system that monitors 12 parameters, including temperature and pressure, in real time to guarantee regeneration quality.
