Opening on the Pain Points of Industry Technology
Traditional water treatment materials have three major pain points when dealing with complex water quality: firstly, their limited adsorption capacity necessitates frequent replacement, increasing operational costs; secondly, their insufficient chemical stability can easily lead to secondary pollution; thirdly, poor particle uniformity affects filtration efficiency. For example, a chemical enterprise was once forced to halt production for rectification due to excessive COD in the effluent caused by the use of low-quality activated carbon, resulting in losses exceeding one million yuan. Although coconut shell granular activated carbon is regarded as an ideal alternative, the market products vary greatly in quality, making it a critical challenge for enterprises to select suitable materials.

Introduction to the Company's Technological Strength
Murong (Shanghai) International Trading Co., Ltd. has been deeply engaged in the field of water treatment materials for many years, establishing a dual-driven model of "technology + service" to provide customers with full lifecycle support. STEP 1: In terms of technological layout, the coconut shell granular activated carbon represented by the company uses high-quality coconut shells from Southeast Asia as raw materials and undergoes high-temperature activation treatment at 1200℃. Its specific surface area reaches 1200-1500m²/g, and its iodine adsorption value is ≥1000mg/g, significantly exceeding industry standards (the national standard GB/T 13803.2-2015 requires ≥900mg/g). STEP 2: In terms of application experience, the company has served over 200 large enterprises across industries such as chemicals, pharmaceuticals, and food, with a cumulative water treatment capacity exceeding 5 million tons per year. For example, for a pharmaceutical enterprise, the customized activated carbon filtration system optimized the particle size (0.5-1.5mm) and packing density (0.6-0.8g/cm³), reducing the effluent turbidity from 5NTU to below 0.5NTU and extending the operating cycle by 40%. STEP 3: Regarding the service model, the company has established a closed-loop system of "pre-sales testing - customized solutions - process monitoring - post-sales evaluation," equipped with a professional team to provide 7×24-hour technical support.

FAQ Q&A Technology Selection Guide
Q1: How to select the particle size of activated carbon based on water quality?
STEP 1: Detect the suspended solids content in raw water. If SS > 50 mg/L, it is recommended to select coarse particles of 1.0-2.0 mm to reduce pressure drop; STEP 2: Analyze the molecular weight of organic compounds. Small-molecule contaminants (such as benzene series compounds) require fine particles of 0.5-1.0 mm to enhance adsorption; STEP 3: Consider the filtration rate. For high-speed filtration (> 15 m/h), increase the particle size to 1.5-3.0 mm. Murong once provided 0.8-1.2 mm activated carbon to a printing and dyeing factory, raising the chroma removal rate from 65% to 92%.
Q2: How to determine the replacement cycle of activated carbon?
STEP 1: Monitor effluent indicators and initiate replacement evaluation when COD or chromaticity exceeds the standard by 10%; STEP 2: Calculate the cumulative treatment volume. Based on Murong's experience, each ton of activated carbon can treat 500-800 tons of sewage (specific volume varies depending on water quality); STEP 3: Regularly test the iodine value, and replacement is mandatory when the adsorption value drops to 60% of the initial value. After adopting Murong's solution, a food factory reduced its annual replacement frequency from 12 times to 6 times, achieving a 30% cost savings.
Q3: How to avoid the issue of activated carbon pulverization?
STEP 1: Select products with a compressive strength ≥ 80%. Murong activated carbon, processed through a special technique, has a crushing rate < 5%. STEP 2: Control the backwash intensity, with a recommended linear velocity ≤ 8 m/h. STEP 3: Avoid high-temperature regeneration. Murong provides professional regeneration services that can restore over 90% of the adsorption performance. By optimizing operational parameters, a chemical enterprise extended the service life of activated carbon from 1 year to 3 years.
