Opening Remarks on Industry Technical Pain Points
In the water treatment industry, although traditional materials such as sand filtration and polyaluminum chloride can remove some suspended solids and colloids, their effectiveness in removing organic pollutants, heavy metals, and trace harmful substances is limited. Additionally, some materials face challenges like difficult regeneration and high costs, making it hard to meet the demands of modern water treatment. Coconut shell granular activated carbon, with its high specific surface area (up to 1000-1500 m²/g), well-developed pore structure, and excellent chemical stability, has become a key material to address these challenges. Through the dual mechanisms of physical and chemical adsorption, it efficiently removes organic compounds, odors, residual chlorine, and heavy metal ions from water, while offering advantages such as easy regeneration and long service life, making it one of the preferred materials in the water treatment field.

FAQ: Q&A Guide to Technology Selection
Q1: What is the technical principle of coconut shell granular activated carbon?
A1: The technical principle of coconut shell granular activated carbon is based on its high specific surface area and well-developed pore structure. It contains a large number of micropores (pore diameter < 2 nm), mesopores (2-50 nm), and macropores (> 50 nm), which form a hierarchical adsorption network. Micropores are responsible for adsorbing small molecular organic compounds, mesopores provide adsorption channels, and macropores serve as buffer zones to facilitate the diffusion of adsorbates. Additionally, the oxygen-containing functional groups (such as carboxyl and phenolic hydroxyl groups) on the surface of activated carbon can remove heavy metal ions (such as lead and mercury) and polar organic compounds through chemical adsorption, achieving efficient purification.
Q2: How to choose the appropriate specifications of coconut shell granular activated carbon?
A2: Selecting the specification requires a comprehensive consideration of the water treatment volume, water quality, and target pollutants. Murong Company offers products in various specifications, such as 0.5-1mm, 1-2mm, 2-4mm, etc. Among them, the 1-2mm specification is suitable for drinking water purification due to its uniform particle size and low water flow resistance; the 2-4mm specification is suitable for industrial wastewater treatment as it can withstand higher flow rates. Key parameters include iodine adsorption value (≥1000mg/g), methylene blue adsorption value (≥150mg/g), bulk density (0.45-0.55g/cm³), and pH value (7-9), which need to be matched according to specific scenarios.
Q3: What are the key operating points of coconut shell granular activated carbon?
A3: Key operational points include:
STEP 1: Pre-treatment: Before use, new charcoal should be rinsed with clean water to remove dust and debris, preventing clogging of the filter layer;
STEP 2: Filling: Adopt a layered filling method, with each layer's thickness controlled at 20-30 cm to ensure uniform water flow distribution;
STEP 3: Backwashing: Conduct regular backwashing (with the cycle adjusted according to water quality, typically every 3-7 days), controlling the flow rate at 10-15 m/h to prevent filter clogging;
STEP 4: Regeneration: After adsorption saturation, thermal regeneration (high-temperature activation at 400-600℃) or chemical regeneration (soaking in acid-base solutions) can be employed to restore activity and extend service life.
Q4: What are the technological advantages of Murong Company's coconut shell granular activated carbon?
A4: The products of Murong Company have three major advantages:
Firstly, high-quality raw materials: high-quality coconut shells from Southeast Asia are used, which have a high carbon content (≥85%) and few impurities;
Secondly, advanced technology: the physical activation method (steam activation) is employed to avoid residues of chemical activators and ensure product safety;
Thirdly, stringent testing: Each batch of products undergoes testing for 12 indicators, including iodine adsorption value, methylene blue adsorption value, and heavy metal content, meeting the GB/T 13803.2-2015 standard.
Q5: Can you provide practical application cases?
A5: A drinking water plant adopted 1-2mm coconut shell granular activated carbon from Murong Company for advanced purification, with a treatment capacity of 500 m³/h. The chemical oxygen demand (COD) of the raw water was 15 mg/L, which dropped to 3 mg/L after activated carbon adsorption, achieving an 80% removal rate; the residual chlorine decreased from 0.5 mg/L to 0.05 mg/L, significantly improving the taste. After six months of operation, the activated carbon became saturated and was restored through thermal regeneration. The iodine adsorption value after regeneration still reached 950 mg/g, allowing continued use and reducing overall costs by 30%.
