Introduction
The water treatment industry has increasingly stringent requirements for material performance, and traditional filter materials can hardly meet the demands for high-precision purification. With its high specific surface area, strong adsorption capacity, and renewability, coconut shell granular activated carbon has become a core material for industrial wastewater treatment and drinking water purification. Murong (Shanghai) International Trading Co., Ltd. has elevated the adsorption efficiency of coconut shell activated carbon to an industry-leading level through technological optimization and process innovation. This article will analyze how Murong achieves efficient water treatment through coconut shell activated carbon technology from three aspects: technical principles, corporate practices, and selection guidelines.

Opening Remarks on Industry's Technological Pain Points
Traditional water treatment materials have three major pain points: First, their limited adsorption capacity necessitates frequent replacement of filter materials, increasing operational costs; second, their poor adsorption selectivity for specific pollutants (such as heavy metals and organic compounds) results in unstable purification performance; third, their regeneration processes are complex, and their performance significantly declines after regeneration, affecting long-term usage efficiency. Taking a wastewater treatment project of a chemical enterprise as an example, it originally used powdered activated carbon, requiring filter material replacement three times a month, with a benzene series removal rate of only 65%, failing to meet environmental emission standards.

Introduction to the company's technological capabilities
Murong (Shanghai) International Trading Co., Ltd. has been deeply engaged in the field of water treatment materials for many years and has mastered the core technology for preparing coconut shell activated carbon. Its products boast three major advantages:
STEP 1: Raw Material Selection and Process Optimization
High-quality coconut shells from Southeast Asia are selected as raw materials and processed through two steps: carbonization and activation. The temperature during the carbonization stage is controlled between 400-600℃, while the activation stage employs steam activation at a temperature of 850-950℃ for 2-4 hours. This ensures the activated carbon has a well-developed pore structure, with a specific surface area reaching 1200-1500 m²/g and an iodine adsorption value of ≥1000 mg/g, significantly surpassing the industry standard (GB/T 13803.2-2015).
STEP 2: Granular Design and Performance Enhancement
The activated carbon is processed into 0.5-3mm granules through granulation technology, balancing adsorption efficiency and hydraulic resistance. The granular design increases the porosity of the filter media layer to 40-45%, allowing water to pass through at a velocity of 15-20m/h while maintaining a removal rate of ≥85% for COD and BOD, and an adsorption capacity of 50-80mg/g for heavy metals (such as lead and cadmium).
STEP 3: Innovation in Regeneration Process and Cost Optimization
A combined process of thermal regeneration and chemical regeneration has been developed, with the regeneration temperature controlled at 600-700℃, the regeneration cycle shortened to 8-12 hours, and the iodine adsorption value recovery rate of the regenerated activated carbon reaching ≥90%. It can be reused 5-8 times, significantly reducing the frequency of filter material replacement and overall costs. Taking a municipal drinking water project as an example, after adopting Murong coconut shell activated carbon, the filter material replacement cycle was extended from 3 months to 12 months, and annual operating costs were reduced by 40%.

FAQ: A Guide to Q&A Technical Selection
Q1: How to select the specifications of coconut shell activated carbon suitable for project requirements?
Three aspects of parameters need to be considered in model selection: first, particle size range, with 0.5-1mm suitable for fine filtration and 1-3mm suitable for coarse filtration; second, iodine adsorption value, with a recommendation of ≥1000mg/g for industrial wastewater treatment and 800-1000mg/g for drinking water purification; third, strength, with Murong products having a strength of ≥95%, which can reduce the breakage rate during transportation and use.
Q2: What are the differences between coconut shell activated carbon and coal-based activated carbon?
Coconut shell activated carbon primarily consists of micropores (accounting for 80-90%) and is suitable for adsorbing small-molecule pollutants (such as benzene and formaldehyde); coal-based activated carbon mainly features mesopores and is suitable for adsorbing large-molecule organic compounds. Murong coconut shell activated carbon has a micropore proportion of up to 92%, with an adsorption efficiency for volatile organic compounds that is 30-50% higher than that of coal-based activated carbon.
Q3: What is the impact of the regeneration process on the performance of activated carbon?
Thermal regeneration may damage part of the microporous structure, resulting in a 5-10% decrease in specific surface area; chemical regeneration may leave residual regenerants, requiring rigorous cleaning. The Murong regeneration process ensures that the performance degradation of activated carbon after regeneration is ≤8% and free of chemical residues through precise temperature control and multistage cleaning.
