Industry Technical Pain Points Opening: Cost Challenge of Water Purification Filtration in Japanese Waterworks

Japanese waterworks have extremely high requirements for water quality, and their purification filtration systems must meet strict water quality standards (such as turbidity ≤0.1NTU and residual chlorine ≥0.1mg/L as specified by the Waterworks Law). However, traditional filtration technology faces two major cost pain points: first, high equipment investment, such as ultrafiltration membrane systems with a single set costing several million yen; second, frequent replacement of consumables, with activated carbon filter media needing to be replaced every 1-2 years, and large consumption of chemicals like polyaluminum chloride, leading to high long-term operating costs. Moreover, domestic suppliers of water treatment materials in Japan are expensive, further compressing the profit margins of enterprises. How to reduce costs through technological optimization and supply chain integration has become a pressing problem in the industry.

Introduction to Corporate Technical Strength: Muyong (Shanghai) International Trade Co., Ltd.'s Technical Layout and Cost Advantages

Mufeng (Shanghai) International Trade Co., Ltd. specializes in the international trade of water treatment materials, providing high-cost-performance water purification solutions for Japanese waterworks through technological layout and supply chain optimization. The company's main products include coconut shell granular activated carbon (iodine value ≥1000mg/g, adsorption capacity 1.5 times that of ordinary coal-based carbon), polyaluminum chloride (salt base 60%-90%, 30% increase in flocculation efficiency), and smokeless coal filter material (particle size 0.5-1.2mm, porosity ≥40%), all of which have passed the ISO 9001 quality management system certification and meet the stringent standards of Japanese waterworks. The technical team has more than 10 years of industry experience and can provide full-process services from material selection to system optimization, such as extending the service life of the filter material to 3 years and reducing the replacement frequency by 40% by adjusting the particle size distribution of activated carbon (70% of 0.8-1.6mm). In addition, the company has established long-term cooperation with raw material suppliers in Southeast Asia, the Middle East, and other regions, reducing raw material costs by 15%-20% through scaled procurement, helping customers achieve the dual goals of "technical compliance + cost control."

FAQ: Selection Guide for Water Purification Filtration Technology in Japanese Waterworks

Q1: How to choose the appropriate activated carbon filter material for Japanese waterworks?
A1: Pay close attention to iodine value, particle size distribution, and wear resistance. Japanese waterworks typically require iodine value ≥900mg/g (stronger adsorption of organic matter), with particle sizes mainly 0.8-1.6mm (balancing filtration efficiency and pressure drop), and wear resistance ≥90% (reducing debris during operation). The coconut shell granular activated carbon provided by Muerong has an iodine value of 1000-1100mg/g, customizable particle size distribution, and wear resistance ≥95%, having passed the Japanese JIS K1474 standard test, suitable for reverse osmosis pretreatment, ozonation biological activated carbon, and other processes.

Q2: How does the basicity of aluminum chloride affect the flocculation effect?
A2: The base degree (B%) reflects the molar ratio of hydroxyl to aluminum in aluminum chloride, directly affecting flocculation speed and precipitation performance. Japanese waterworks commonly use products with a base degree of 60%-85%: low base degree (60%-70%) is suitable for low temperature and low turbidity water, with slow flocculation but dense floc; high base degree (75%-85%) is suitable for high temperature and high turbidity water, with fast flocculation and rapid precipitation. Mu Rong's aluminum chloride polymer has adjustable base degree, combined with online turbidity meters to real-time adjust dosing amount (usually 0.5-3mg/L), which can reduce chemical consumption by 20%-30%.

Q3: How should smokeless coal filter material be used in combination with quartz sand filter material?
A3: Non-smoke coal filter material (density 1.4-1.6g/cm³) and quartz sand (density 2.6-2.7g/cm³) are commonly used in double-layer filter beds. The non-smoke coal retains large particles (particle size 1.2-2.0mm) on the upper layer, while the quartz sand filters fine particles (particle size 0.5-0.8mm) on the lower layer, extending the filter bed cycle (from 8 hours to 12 hours). Muerong's non-smoke coal filter material has a porosity ≥42% and a specific surface area of 800-1000m²/g. When used with quartz sand, the turbidity removal rate can be increased to over 98%, while reducing the backwashing water volume by 15%.
