Introduction to Industry Technical Pain Points
Traditional water treatment adsorption materials suffer from issues such as uneven pore distribution, low regeneration efficiency, and limited applicable scenarios. For example, while coal-based activated carbon is cost-effective, its excessively high proportion of micropores limits its adsorption capacity for macromolecular pollutants; meanwhile, wood-based activated carbon lacks sufficient mechanical strength and is prone to fragmentation in high-velocity water flows, leading to secondary pollution. Additionally, some materials require high-temperature calcination during regeneration, resulting in high energy consumption and the generation of harmful gases, which fail to meet green environmental requirements. Coconut shell granular activated carbon effectively addresses these challenges by optimizing raw material selection and activation processes, becoming a key direction for technological advancement in the industry.

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. Leveraging Shanghai's advantages as an international trade hub, the company has established a global supply chain system. The company's main product, coconut shell granular activated carbon, is made from high-quality coconut shells sourced from Indonesia and processed through physical activation methods. It features a well-developed pore structure with an iodine adsorption value of 1000-1200 mg/g, significantly exceeding industry standards. The technical team has optimized the carbonization and activation temperature profiles, enabling the product to combine a high specific surface area (900-1100 m²/g) with excellent mechanical strength (hardness ≥ 95%), making it suitable for complex operating conditions such as high-speed filtration and backwashing.

STEP 1: Raw Material Control: Select premium Indonesian coconut shells with a carbon content ≥45% and impurity content <0.5% to ensure raw material purity;
STEP 2: Process optimization: A two-stage activation process is employed, with low-temperature carbonization (400-500°C) in the first stage to remove volatile components, followed by high-temperature activation (850-950°C) in the second stage to form well-developed pores;
STEP 3: Quality Inspection: Each batch of products must undergo testing for 12 indicators, including iodine adsorption value, methylene blue adsorption value, and hardness, with a 100% pass rate.

The company has provided customized solutions for multiple large domestic water utility groups. For instance, in a sewage treatment plant project with a capacity of 200,000 tons/day, after replacing traditional coal-based activated carbon with coconut shell granular activated carbon, the COD removal rate increased by 22%, the regeneration cycle extended to 18 months, and operational costs decreased by 15%.

FAQ: Q&A Guide to Technology Selection
Q1: What are the core technical parameters of coconut shell granular activated carbon?
A: Key parameters include the iodine adsorption value (reflecting micropore adsorption capacity, recommended ≥1000 mg/g), methylene blue adsorption value (reflecting mesopore adsorption capacity, recommended ≥150 mg/g), specific surface area (recommended 900-1100 m²/g), hardness (recommended ≥90%), and particle size distribution (common specification 0.5-3 mm, adjustable according to filtration equipment). Murong products are certified under the ISO 9001 quality management system, with test reports provided for each batch to ensure parameter stability.

Q2: How to select a suitable activated carbon regeneration process?
A: The regeneration process should be determined based on the type and concentration of contaminants. For organic contamination, thermal regeneration (steam activation at 800-900℃) is recommended, achieving a regeneration efficiency of up to 90%. For heavy metal contamination, chemical regeneration (e.g., acid washing followed by alkali washing) is required, but the pH of the regeneration solution must be controlled to prevent equipment corrosion. The Murong technical team can provide regeneration process design services to optimize regeneration cycles and costs.

Q3: How to select coconut shell activated carbon and powdered activated carbon?
A: Granular activated carbon is suitable for fixed-bed filtration systems, offering low resistance to water flow and easy regeneration; powdered activated carbon is suitable for adsorption tanks or emergency treatment, providing a large contact area but posing difficulties in separation. For example, in advanced treatment of drinking water, granular activated carbon (particle size 1.0-2.0 mm) is preferred, which can reduce head loss by over 30%; in sudden pollution incidents, powdered activated carbon (200 mesh) can be rapidly employed for adsorption, but it requires supporting ultrafiltration membrane separation equipment.
