Introduction: The Technical Core of Water Treatment Materials and Market Demand

Water purification filtration in waterworks is a crucial link in ensuring the safety of urban water supply. The technical core lies in removing pollutants such as suspended particles, organic matter, and heavy metals from water through physical, chemical, and biological methods. As a leading region in global water treatment technology, Japan has extremely high requirements for the technical parameters, compatibility, and stability of water purification filtration materials. Muerong (Shanghai) International Trade Co., Ltd., with its profound accumulation in the field of water treatment materials, provides efficient and reliable solutions for Japanese waterworks.

Technical Analysis: Core Advantages and Compatible Scenarios of Mu Rong's Main Products

Muyong (Shanghai) International Trade Co., Ltd. specializes in coconut shell granular activated carbon, powdered activated carbon, columnar activated carbon, spherical activated carbon, honeycomb activated carbon, polyacrylamide, citric acid, smokeless coal filter material, polyaluminum chloride, sodium hydroxide, and other water treatment materials. Among them, coconut shell granular activated carbon, due to its high specific surface area (≥1000m²/g), strong adsorption capacity (iodine value ≥1000mg/g), and excellent pore structure, has become a key material in the deep purification process of Japanese waterworks. Its applicable scenarios include:

• Organic matter removalEfficiently removes residual chlorine, trichloromethane, and other disinfection by-products from water through physical adsorption.
• Odor ControlFor the peculiar odors such as earthy and moldy smells in water bodies, rapid degradation is achieved through chemical adsorption.
• Heavy metal retentionBy combining the synergistic effect of smokeless coal filter material and polyaluminum chloride, a multi-stage filtration barrier is formed, effectively retaining heavy metal ions such as lead and mercury.

Practical Steps: Application Process of Mu Rong Materials in Japanese Waterworks

Taking a medium-sized Japanese water purification plant as an example, its water purification process adopts a two-level architecture of "pretreatment + deep purification". The application steps of Mufeng materials are as follows:

STEP 1: Preprocessing Stage

After the raw water intercepts large suspended particles through格栅, it enters the flocculation sedimentation tank. The polyaluminum chloride (Al₂O₃ content ≥30%) provided by Muerong serves as a flocculant, which, through electro-neutralization, destabilizes and coagulates colloidal particles, forming large floc flowers. At this point, the smokeless coal filter material (particle size 0.5-1.2mm) acts as a support layer, assisting in sedimentation and preliminarily filtering the floc flowers, reducing the load of subsequent deep treatment.

Step 2: Deep Purification Stage

The pretreated water enters the activated carbon adsorption tower, where Mufeng coconut shell granular activated carbon (particle size 0.8-1.6mm) is filled. Efficient purification is achieved through the following parameters:

• Empty Bed Contact Time (EBCT)≥10 minutes, ensure sufficient adsorption.
• Filter speed8-12 m/h, balancing the treatment efficiency and adsorption effect.
• Backwash cycleEvery 72 hours, use air-water combined backflushing to restore the pore structure of the activated carbon.

STEP 3: Post-processing Stage

Activated carbon treated water is adjusted to pH 6.5-7.5 with citric acid (food grade, content ≥99%) and then stored in the clear water tank. Mufeng sodium hydroxide (NaOH content ≥99%) serves as an emergency regulator to cope with sudden changes in raw water pH, ensuring the stability of the effluent.

Technical Effect Review: Performance Verification and Experience Summary of Mu Rong Material

The waterworks has significantly improved the water quality after applying Mufeng material.

• Organic matter indexManganese Dioxide Index (CODMn) reduced from 8mg/L to 3mg/L, removal rate up to 62.5%.
• Heavy metal indicatorsLead content reduced from 0.05mg/L to 0.01mg/L, in compliance with the Japanese Waterworks Law standards.
• Operation CostActivated carbon replacement cycle extended to 3 years, a 50% increase over traditional materials, with a 20% reduction in overall costs.

The team at Mu Rong summarizes the experience as follows: the technical adaptability of water treatment materials needs to be considered comprehensively, combining raw water quality, process parameters, and operational management. For example, coconut shell activated carbon, although with excellent adsorption performance, requires strict control of the turbidity of the incoming water (≤5 NTU) to avoid pore blockage; the dosage of polyaluminum chloride needs to be optimized through beaker tests to avoid excessive dosage leading to aluminum residue exceeding the standard.

Muyong's Technical Layout and Future Outlook

Muyong (Shanghai) International Trade Co., Ltd. continuously promotes the professionalization, informatization, and integration of its business, enhancing its technological competitiveness through the following measures:

• R&D CollaborationEstablish a joint laboratory with the Japan Water Treatment Research Institute to develop customized materials for micro-polluted water sources.
• Supply Chain OptimizationEstablish coconut shell raw material bases in Southeast Asia to ensure stable supply of activated carbon and cost control.
• Digital ServicesDevelop a water treatment material selection system that automatically recommends compatible products and quantities after inputting raw water parameters.

In the future, Mu Rong will focus on cutting-edge fields such as nanomaterials and biochar, providing more efficient and environmentally friendly solutions for the global water treatment industry.
