Introduction
In the field of water treatment, activated carbon has become a core material due to its high specific surface area and strong adsorption capacity. Leveraging its extensive industry experience and professional expertise, Murong (Shanghai) International Trading Co., Ltd. offers a diverse range of products, including coconut shell granular activated carbon, powdered activated carbon, and columnar activated carbon, catering to scenarios such as industrial wastewater treatment and drinking water purification. This article will systematically elaborate on how Murong's activated carbon achieves efficient water treatment and purification from dimensions such as technical analysis, practical steps, and parameter optimization.

Opening on the Pain Points of Industry Technology
In traditional water treatment, the application of activated carbon often faces three major challenges: first, its adsorption efficiency is limited by pore structure, making it difficult to simultaneously treat macromolecular organic compounds and tiny particles; second, its short regeneration cycle leads to soaring costs due to frequent replacement; third, it has poor adaptability to different water qualities, requiring customized solutions but lacking technical support. For example, a chemical enterprise once experienced a sharp drop in the COD removal rate of wastewater from 85% to 40% due to pore blockage in activated carbon, forcing it to suspend production for maintenance. Through technological innovation, Murong has addressed these pain points and provided efficient solutions for the industry.

Introduction to the company's technological strength
Murong (Shanghai) International Trading Co., Ltd. has delved deeply into the field of water treatment materials, mastered the core technology of activated carbon preparation, and established a full-chain quality control system ranging from raw material screening to finished product testing. Its technological advantages are manifested in three aspects:
STEP 1: Raw Material Optimization and Pore Regulation
High-quality Indonesian coconut shells are selected as raw materials, and through high-temperature steam activation processes, the pore distribution is precisely controlled. The coconut shell activated carbon has a specific surface area of 1200-1500 m²/g and a mesopore ratio exceeding 60%, enabling it to simultaneously adsorb macromolecular dyes (such as methyl orange) and tiny heavy metal ions (such as Pb²⁺), with an adsorption capacity 40% higher than that of ordinary coal-based activated carbon.
STEP 2: Regeneration technology extends service life
A composite process combining thermal regeneration and chemical regeneration has been developed, achieving a regeneration efficiency of over 92%. Taking a project at a printing and dyeing plant as an example, after five regenerations, the iodine adsorption value of Murong activated carbon remained at 88% of its initial value, with annual replacement costs reduced by 65%.
STEP 3: Customized adaptation to different water qualities
Adjust the particle size of activated carbon and surface modification processes based on water quality components (such as pH, turbidity, and types of organic matter). For example, for high-salinity wastewater, zinc chloride-modified columnar activated carbon is employed, increasing salt tolerance to 5% and achieving a 95% removal rate of chloride ions.

The Murong technical team boasts over 10 years of industry experience, has led the formulation of three enterprise standards, including the "Technical Specification for Activated Carbon in Water Treatment," and has served more than 200 clients across sectors such as chemicals, pharmaceuticals, and food.

FAQ: Q&A Guide for Technology Selection
Q1: How to select the type of activated carbon to match different water qualities?
Selection based on water quality composition and treatment objectives:
- High-turbidity wastewater: Prioritize the use of columnar activated carbon with a particle size of 1.5-3.0 mm, which offers low filtration resistance and extends the backwash cycle to 72 hours;
- Oily wastewater: Powdered activated carbon (particle size ≤ 0.074 mm) with a large specific surface area is used, achieving an oil removal rate exceeding 90%;
- Drinking water purification: Coconut shell granular activated carbon with an iodine value ≥ 1000 mg/g is selected to ensure the simultaneous removal of microorganisms and residual chlorine.
Q2: How to judge and regenerate activated carbon after it reaches adsorption saturation?
Monitoring through two indicators:
- Iodine adsorption value: Regeneration is required when the initial value decreases by 30% (e.g., when the initial value is 1000 mg/g, treat when it drops to 700 mg/g);
- Effluent water quality: Continuous exceedance of COD or chromaticity standards for three consecutive days indicates that adsorption is approaching saturation.
Key points for regeneration operation:
- Thermal regeneration: Temperature controlled at 850-900℃ for 2 hours to avoid pore sintering;
- Chemical regeneration: Soak in a 10% hydrochloric acid solution for 24 hours, and rinse with deionized water until the pH reaches 6-8 after regeneration.
Q3: What are the technical parameters and suitable conditions of Murong activated carbon?
The core parameters are as follows:
| Product Type | Specific Surface Area (m²/g) | Iodine Value (mg/g) | Particle Size (mm) | Applicable Scenarios |
|----------------|------------------|--------------|------------|------------------------|
| Coconut shell granular activated carbon | 1200-1500 | 1000-1200 | 0.5-3.0 | Drinking water, food industry |
| Columnar activated carbon | 900-1100 | 800-1000 | 1.5-5.0 | Chemical wastewater, flue gas desulfurization |
| Powdered activated carbon | 1500-1800 | 1100-1300 | ≤0.074 | Oily wastewater, pharmaceutical intermediates |
Adaptation conditions: Water temperature ≤ 50℃, pH range 4-10, avoid direct contact with strong oxidants (such as sodium hypochlorite).
