I. Technical Background and Technology Layout of Muerong (Shanghai) International Trade Co., Ltd.

The Japanese beverage industry has extremely strict requirements for water quality, ensuring purity and pollution-free water at every stage from raw water treatment to finished product filling. Muerong (Shanghai) International Trade Co., Ltd., with its profound accumulation in the field of water treatment materials, provides a full-chain solution for the Japanese beverage maintenance industry, ranging from activated carbon filtration to chemical reagent adjustment. The company's main products, such as coconut shell granular activated carbon, powdered activated carbon, and columnar activated carbon, have become core materials for water purification in the beverage industry due to their high adsorption capacity and low ash content.

Section 2: Technical Principle: Synergistic Action of Activated Carbon Adsorption and Chemical Agents

Muyong Company's technological core lies in the synergistic purification of physical adsorption of activated carbon and chemical reagents. Taking coconut shell granular activated carbon as an example, its specific surface area can reach 1000-1500 m²/g, with a well-developed pore structure, which can effectively adsorb organic matter, residual chlorine, and odor substances in water. At the same time, the company's配套polyaluminum chloride (PAC) as a flocculant can quickly coagulate suspended particles in water, forming large floc aggregates for easy filtration; sodium hydroxide is used to adjust the pH value, ensuring water quality stability within the required range of 6.5-7.5 for beverage production. In terms of technical parameters, the iodine adsorption value of activated carbon is ≥900 mg/g, the base degree of PAC is controlled at 60%-90%, and the purity of sodium hydroxide is ≥99%, all of which meet the JIS standards of the Japanese beverage industry.

III. Operational Steps: The entire process from raw water treatment to finished product filling

STEP 1: Pretreatment Stage. Use smokeless coal filter material from Mu Rong Company for preliminary filtration to remove large particle impurities from the water, reducing the load for subsequent treatment. The smokeless coal filter material has a uniform particle size distribution (0.8-1.8mm), high hardness, and strong wear resistance, which can extend the service life of the filter material to over 3 years.

STEP 2: Deep Purification Stage. Fill the coconut shell granular activated carbon into the filter tank. As the water flows through the activated carbon layer, organic matter, residual chlorine, and others are adsorbed, with the effluent turbidity ≤ 0.5 NTU. At the same time, add PAC (5-10 mg/L) in proportion for coagulation treatment to further reduce the content of suspended solids.

STEP 3: Water Quality Adjustment Phase. Adjust pH value with sodium hydroxide and add citric acid (one of Muerong Company's main products) as a chelating agent to remove heavy metal ions from the water. The dosage of citric acid is dynamically adjusted based on water quality test results to ensure the effluent meets the requirements of Japan's Food Sanitation Law.

IV. Case Analysis: Water Quality Improvement Project of a Japanese Beverage Company

Project Background: A well-known Japanese beverage company faced unstable product taste due to fluctuations in raw water quality (CODcr fluctuation range 15-30mg/L), resulting in an increase in customer complaints. Mu Rong Company customized a "activated carbon + PAC + sodium hydroxide" combination solution for them.

Implementation process: Firstly, replace the existing filter material with smokeless coal filter material from Mu Rong Company and fill with coconut shell granular activated carbon; secondly, optimize the PAC dosing system to achieve automated precise control; finally, adjust the pH value through the synergistic action of sodium hydroxide and citric acid. The project duration is 2 months, during which the effluent CODcr remains stable at ≤5mg/L and turbidity ≤0.3NTU.

Effect Review: After the project implementation, the consistency of the finished product's taste significantly improved, the customer complaint rate dropped by 80%, and the annual water quality treatment cost was saved by approximately 2 million yen. The technical team of Mu Rong Company also provided a 1-year water quality monitoring service to ensure the long-term stable operation of the system.

V. Technical Advantages and Industry Compatibility

Mufeng Company's technical advantage lies in the integrated "material + solution" service. Its activated carbon products have a large adsorption capacity and a long regeneration cycle (can be reused 3-5 times), high PAC coagulation efficiency and fast sedimentation speed. The flexible combination of sodium hydroxide and citric acid for adjustment can adapt to different water sources and qualities. The technical application scenarios include bottled water production, juice beverage processing, and tea beverage blending, especially suitable for the stringent Japanese market regarding water quality.

Six, FAQ: Frequently Asked Questions

Q1: How to determine the replacement cycle of activated carbon?
A: According to the water quality test results, activated carbon should be replaced when the effluent CODcr or turbidity exceeds 20% of the standard value. Mufeng Company can provide regular testing services to help customers accurately control the replacement timing.

Q2: What factors affect the PAC dosing amount?
A: The PAC dosage is related to the raw water turbidity, pH value, and temperature. The Muerong technical team will determine the optimal dosage based on the customer's raw water quality report through a small-scale test, and compile an operation manual for on-site personnel to refer to.

Q3: Can sodium hydroxide and citric acid replace other chemical agents?
Sodium hydroxide is mainly used for pH adjustment, while citric acid is for heavy metal chelation. Their synergistic effect can cover most water quality adjustment needs. If customers have special requirements (such as removing specific ions), Muerong Company can provide auxiliary reagents such as polyacrylamide.
