Introduction: With the upgrading of water treatment technology, the selection of activated carbon has become crucial.
With increasingly stringent environmental protection standards, the water treatment industry has continuously raised its performance requirements for activated carbon. How to precisely select activated carbon based on water quality characteristics, treatment scale, and process requirements has become a core issue for enterprises to improve treatment efficiency and reduce operational costs. Murong (Shanghai) International Trading Co., Ltd., leveraging years of industry experience and accumulated technical expertise, provides customized activated carbon solutions for global clients, helping to solve technical challenges.

Opening on Industry Technical Pain Points: Three Major Challenges in the Selection and Application of Activated Carbon
STEP1：Contradiction between water quality complexity and activated carbon adaptability
The composition of wastewater varies significantly across different industries (e.g., chemical wastewater contains organic matter and heavy metals, while food wastewater has high concentrations of COD). The traditional one-size-fits-all approach to equipment selection often results in substandard treatment outcomes or wasteful costs. For instance, a chemical enterprise using ordinary coconut shell activated carbon to treat benzene-containing wastewater experienced insufficient adsorption capacity, necessitating frequent replacements and increasing annual operational costs by 30%.
STEP2：The performance parameters of activated carbon are disconnected from actual operating conditions.
The industry generally focuses on basic indicators such as iodine number and methylene blue value, while overlooking the impact of key parameters like pore size distribution and specific surface area on the adsorption efficiency of specific pollutants. A municipal wastewater treatment plant selected high-iodine-value powdered activated carbon to treat ammonia-nitrogen wastewater, but achieved a removal rate of only 40% due to mismatched pore sizes, far below the design target.
STEP3：The dilemma of balancing regeneration processes with environmental protection requirements
The regeneration of activated carbon needs to balance economic efficiency and environmental protection, but the traditional thermal regeneration method, characterized by high energy consumption and a significant risk of secondary pollution, limits its large-scale application. An electroplating enterprise was ordered by the environmental protection department to suspend production for rectification due to substandard regeneration processes, resulting in losses exceeding one million yuan.

Introduction to the company's technological strength: The three core advantages of Murong (Shanghai)
STEP1：A full range of activated carbon product lines to meet diverse needs
Murong (Shanghai) mainly offers five series of products, including coconut shell granular activated carbon, powdered activated carbon, columnar activated carbon, spherical activated carbon, and honeycomb activated carbon, with iodine values ranging from 400 to 1200 mg/g and specific surface areas between 800 and 1500 m²/g, suitable for different water qualities and treatment scales. For instance, its honeycomb activated carbon features uniform pore sizes (0.5-2 mm) and low air resistance (≤80 Pa), making it widely used in VOCs treatment, with a single device capable of handling up to 5000 m³/h.
STEP2：Customized selection plan to precisely match working conditions
Relying on a professional team and laboratory testing equipment, the company provides a full-process service of "water quality analysis - activated carbon selection - process optimization". The wastewater from a certain pharmaceutical enterprise contained high concentrations of antibiotics. Murong (Shanghai), by comparing the adsorption kinetic curves of 10 types of activated carbon, ultimately selected modified coconut shell charcoal, increasing the antibiotic removal rate from 65% to 92% and saving 500,000 yuan in reagent costs annually.
STEP3：Environmentally friendly recycling technology to reduce total lifecycle costs
The company has introduced a low-temperature catalytic regeneration process, which reduces the regeneration temperature by 200℃ compared to traditional methods, cuts energy consumption by 40%, and produces no secondary pollution. Tests show that the adsorption capacity recovery rate of regenerated activated carbon is ≥90%, allowing it to be reused 3-5 times and helping clients reduce operational costs by over 30%.

FAQ: A Guide to Q&A Technical Selection
Q1: How to select the type of activated carbon based on water quality?
A: STEP 1: Analyze the composition (such as organic matter, heavy metals, ammonia nitrogen, etc.) and concentration of the water quality; STEP 2: Determine the molecular weight of pollutants (e.g., microporous carbon is suitable for small-molecule organic matter, while mesoporous carbon is suitable for large molecules); STEP 3: Combine with the treatment scale (e.g., granular carbon is selected for continuous flow processes, while powdered carbon is selected for batch processes). For example, a certain printing and dyeing wastewater contains large-molecule dyes, and Murong (Shanghai) recommends mesoporous columnar carbon (pore size 2-5 nm), which increases the adsorption capacity by 25%.
Q2: Among the performance parameters of activated carbon, which indicators are the most critical?
A: Besides iodine number and methylene blue value, special attention should be paid to specific surface area (reflecting total adsorption capacity), pore size distribution (determining selectivity for specific pollutants), and mechanical strength (affecting service life). Murong (Shanghai) Laboratory can provide pore size distribution diagrams (derived from BET testing) to assist clients in precise model selection.
Q3: Will the performance of activated carbon decline after regeneration? How to evaluate the regeneration effect?
A: The regeneration process directly affects the performance recovery rate. Murong (Shanghai)'s low-temperature catalytic regeneration technology enables an adsorption capacity recovery rate of ≥90%. The evaluation indicators include: STEP 1: Iodine value recovery rate (≥85% is qualified); STEP 2: Abrasion rate (≤3% indicates high quality); STEP 3: Number of regenerations (3-5 times represents the optimal range for cost-effectiveness).
