Introduction: Coconut Shell Granular Activated Carbon—the "Adsorption Expert" in the Field of Water Treatment
The water treatment industry has increasingly stringent requirements for the adsorption performance of materials, and traditional filter materials can hardly meet the needs of high-precision purification. With its well-developed pore structure, high specific surface area, and excellent chemical stability, coconut shell granular activated carbon has become a core material for industrial wastewater treatment and advanced drinking water purification. This article will analyze how Murong (Shanghai) International Trading Co., Ltd. maximizes water treatment efficiency through coconut shell granular activated carbon from three aspects: technical principles, parameter optimization, and practical case studies.

Opening on Industry's Technological Pain Points: Limitations of Traditional Water Treatment Materials
STEP 1: Traditional filter materials (such as quartz sand and anthracite) have limited adsorption capacity, with a removal rate of organic compounds and heavy metals of less than 60%, making it difficult to meet the requirements in the "Standards for Drinking Water Quality" (GB 5749-2022) of COD ≤ 3 mg/L and lead ≤ 0.01 mg/L.
STEP 2: Although powdered activated carbon has strong adsorption performance, it is prone to loss and difficult to regenerate, resulting in an increase of over 30% in operating costs; columnar activated carbon has uneven pore distribution and poor retention of small-molecule pollutants.
STEP 3: Some companies opt for low-quality coconut shell charcoal to reduce costs, with an iodine adsorption value < 800 mg/g and a methylene blue adsorption value < 120 mg/g, making it unable to effectively remove odors, residual chlorine, and micro-pollutants from water.

Introduction to the company's technological strength: Coconut Shell Charcoal Technology Layout of Murong International
Murong (Shanghai) International Trading Co., Ltd. has been deeply engaged in the trade of water treatment materials for 12 years, establishing a full-chain technical system encompassing "raw material control - process optimization - application support":
STEP 1: Strict Raw Material Selection: Establish long-term cooperation with high-quality coconut shell suppliers in Southeast Asia to ensure raw materials with a carbon content ≥85% and ash content ≤8%, laying the foundation for high adsorption performance.
STEP 2: Process upgrading: Adopting the dual process of "physical activation + chemical modification" to achieve an iodine adsorption value of 1000-1200 mg/g, a methylene blue adsorption value of 150-180 mg/g, and a porosity of ≥65% for the product, significantly surpassing industry standards.
STEP 3: Application Support: Establish a technical team composed of experts in chemical engineering and environmental science to provide customers with a one-stop service covering "model selection - commissioning - maintenance," with a cumulative total of over 200 service projects and a customer repurchase rate of 90%.
Technical parameter example: The Murong coconut shell granular activated carbon has a specification of 0.5-3mm, a bulk density of 0.45-0.55g/cm³, a pH value of 6-9, a strength of ≥90%, can withstand water temperatures ≤80℃, and is suitable for scenarios such as reverse osmosis pretreatment and ozone catalytic oxidation.

FAQ Q&A Technical Selection Guide
Q1: How to select the particle size of coconut shell charcoal based on water quality?
A: STEP 1: Test the turbidity and SS content of raw water: If SS > 50 mg/L, it is recommended to use 3-5 mm large-particle carbon to prevent clogging; if SS < 20 mg/L, 0.5-1 mm small-particle carbon can enhance contact efficiency.
STEP 2: Analyze the molecular weight of pollutants: For macromolecular organic compounds (such as humic acid), select 1-3 mm medium-particle-size carbon; for small-molecule pollutants (such as pesticides), 0.5-1 mm fine-particle carbon is required.
STEP 3: Refer to the Murong case: In a certain chemical wastewater project, the raw water COD was 150 mg/L. Using 1-2 mm coconut shell charcoal with an empty bed contact time of 15 minutes, the effluent COD was reduced to 30 mg/L, achieving an 80% removal rate.
Q2: How to determine the regeneration cycle of coconut shell charcoal?
A: STEP 1: Monitor pressure differential: When the pressure differential of the filter bed increases by 30% compared to the initial value, regeneration is required.
STEP 2: Monitor the effluent water quality: If COD and chroma exceed the standard twice consecutively, initiate regeneration immediately.
STEP 3: Murong's recommendation: In industrial wastewater treatment scenarios, the regeneration cycle of coconut shell charcoal is 6-12 months; for drinking water treatment scenarios, it can be extended to 18-24 months. Thermal regeneration (steam activation at 400-600℃) is employed for regeneration, which can restore over 90% of its adsorption performance.

Case Analysis: Application of Murong Coconut Shell Charcoal in Wastewater Treatment at an Electronics Factory
STEP 1: Project Background: The production wastewater from an electronics factory contains heavy metals (nickel, copper) and organic solvents (isopropyl alcohol). The original treatment process (chemical precipitation + sand filtration) resulted in an effluent nickel concentration of 0.2 mg/L, exceeding the standard by 100%.
STEP 2: Technical Solution: Murong provides a combined process of "coconut shell granular activated carbon adsorption + ion exchange", selecting 1-2mm coconut shell carbon, with an empty bed flow rate of 8m/h, a contact time of 20 minutes, and a carbon layer height of 1.5m.
STEP 3: Implementation Effect: After three months of operation, testing revealed that the nickel concentration in the effluent decreased to 0.005 mg/L, and COD dropped from 80 mg/L to 15 mg/L, meeting the requirements of the "Discharge Standard of Water Pollutants for Electronic Industry" (GB 39731-2020).
STEP 4: Economic Analysis: The project processes 100,000 tons of water annually, consumes 15 tons of coconut shell charcoal per year, reduces operating costs by 25% compared to the original process, and has a payback period of only 1.2 years.
