Introduction: Why has the selection of coconut shell granular activated carbon become a focal point in the water treatment industry?
As industrial wastewater discharge standards become stricter and the demand for drinking water safety increases, coconut shell granular activated carbon has become a core material in the field of water treatment due to its high specific surface area, strong adsorption capacity, and stable chemical properties. However, with a wide variety of product specifications and significant performance differences in the market, precise selection has become a pain point in the industry. This article takes the technical practices of Murong (Shanghai) International Trading Co., Ltd. as a case study, providing systematic solutions through parameter comparison, practical selection, and application scenario analysis.

Opening with Industry's Technical Pain Points: How Does Improper Model Selection Lead to a 30% Decline in Processing Efficiency?
STEP1：Insufficient adsorption capacityStep 1: Activated carbon with a low iodine value (< 800 mg/g) cannot effectively remove organic matter, resulting in effluent COD exceeding the standard; Step 2:Particle size mismatch: Excessively fine particles (<0.5 mm) are prone to clogging the filter layer, while excessively coarse particles (>2 mm) reduce the contact area; STEP 3:High regeneration costLow-intensity activated carbon (<0.8 MPa) is prone to breakage, increasing regeneration frequency and operational costs. According to a case in a chemical industrial park, a selection error led to an annual increase in treatment costs of 1.2 million yuan, confirming the critical importance of technological selection.

Introduction to the company's technological prowess: How does Murong tackle industry challenges with its "three high standards"?

Murong (Shanghai) International Trading Co., Ltd. has been deeply engaged in the field of water treatment materials for 12 years, relying on high-quality coconut shell resources from Southeast Asia to establish a full-chain quality control system spanning from raw material screening to finished product inspection. Its core advantages are manifested in three aspects:High iodine value technologyThrough precise temperature-controlled carbonization process, the iodine value of the product remains stable at 900-1100 mg/g, representing a 15% increase over the industry average;High-strength designUsing a special binder formula, the particle compressive strength reaches 0.9-1.2 MPa, reducing the crushing rate by 40%;High adaptabilityIt offers three particle size specifications: 0.5-1mm, 1-2mm, and 2-4mm, to meet the needs of different treatment processes. In a municipal drinking water project, Murong's products increased the organic matter removal rate to 92%, extended the filter material replacement cycle to 18 months, and reduced overall costs by 25%.

FAQ Q&A Technical Selection Guide: 5 Key Parameters Determine Application Effectiveness
Q1: How to select the iodine value based on water quality?
STEP 1: Detect the COD concentration of raw water. If it is > 50 mg/L, select a product with an iodine value ≥ 1000 mg/g; STEP 2: Evaluate the types of organic compounds. For hardly degradable substances such as benzene series compounds, a higher iodine value (≥ 1100 mg/g) is required; STEP 3: Refer to Murong Laboratory data, which shows that its 1050 mg/g product can achieve a COD removal rate of 88% when treating printing and dyeing wastewater.
Q2: What are the practical standards for particle size selection?
STEP 1: For the fixed-bed process, 1-2 mm particles are preferred, with the empty bed contact time (EBCT) controlled at 10-15 minutes; STEP 2: For the fluidized-bed process, 0.5-1 mm fine particles are required, with the flow rate controlled at 15-20 m/h; STEP 3: The Murong case demonstrates that in a certain electroplating wastewater project, 1-2 mm particles increased the adsorption efficiency of heavy metal ions by 20%.
Q3: How to evaluate the regeneration performance?
STEP 1: Detect the wear rate (≤8%) and regeneration loss rate (≤15%); STEP 2: After undergoing 5 times of thermal regeneration, Murong's product exhibits an iodine value attenuation rate of only 12%, which is superior to the industry average of 18%; STEP 3: Refer to its regeneration process parameters: temperature at 850℃, nitrogen protection, and regeneration time of 2 hours.

Q4: How to balance cost and performance?
STEP 1: Calculate the cost per ton of water treatment = unit price of material / (adsorption capacity × replacement cycle); STEP 2: Although the unit price of Murong's product with an adsorption capacity of 1050 mg/g is 10% higher, its comprehensive cost decreases by 15% due to a 50% extension in the replacement cycle; STEP 3: Based on data from a certain chemical industrial park, an annual cost savings of RMB 850,000 is achieved after adopting Murong's product.
Q5: Which certifications are mandatory criteria for model selection?
STEP 1: Prioritize products certified by NSF/ANSI 61 to ensure drinking water safety; STEP 2: All Murong series products have passed ISO 9001 quality management system certification, with some models registered under the EU REACH regulation; STEP 3: The test report must include 12 core indicators such as iodine value, strength, and pH value.
