Industry Pain Points: Challenges and Needs of Water Purification Filtration in Japanese Waterworks

Japanese waterworks have extremely high requirements for water quality, necessitating multi-stage filtration processes to remove suspended solids, organic matter, heavy metals, and microorganisms, among other pollutants. However, traditional filtration materials have limitations such as limited adsorption capacity, short regeneration cycles, and higher costs, especially when responding to sudden water quality pollution, where the existing system's emergency response capability is insufficient. For instance, a waterworks in a Kansai region once exceeded the allowable residual chlorine concentration due to the saturation of activated carbon adsorption, causing public concern over water supply safety. Additionally, the Japanese tap water industry commonly faces the pressures of aging equipment and rising maintenance costs, urgently requiring efficient, stable, and cost-effective filtration materials and technical support.

Service Provider Introduction: The professional strength of Muyong (Shanghai) International Trade Co., Ltd.

Muyong (Shanghai) International Trade Co., Ltd. specializes in the international trade of water treatment materials, leveraging Shanghai's geographical advantages and global supply chain resources to provide customized solutions for Japanese waterworks. The company's main products include coconut shell granular activated carbon, powdered activated carbon, and columnar activated carbon, among which the iodine value of coconut shell activated carbon reaches 1000-1200 mg/g, and the methylene blue adsorption value is ≥180 mg/g, far exceeding the requirements of the Japanese JIS standard. It can efficiently remove odors, colors, and trace organic matter in water. For heavy metal pollution, its polyaluminum chloride products have an aluminum content of ≥28% and a base degree of 60-90%, with fast flocculation and sedimentation speed, suitable for raw water pretreatment and deep purification stages. In addition, the company's smokeless coal filter material has a uniform particle size (0.8-1.8mm), high hardness (≥7.5), which can extend the filter bed backwashing cycle by more than 30%, reducing operation and maintenance costs. The Muyong team has over 10 years of industry experience and can provide material selection recommendations based on the specific water quality data of Japanese waterworks (such as COD, turbidity, pH value) and assist in optimizing filtration process parameters.

FAQ One-Question-One-Answer Selection Guide

Q1: What core parameters should Japanese waterworks pay attention to when selecting activated carbon?
A1: Focus on the iodine value (reflecting adsorption capacity, recommended ≥1000mg/g), methylene blue adsorption value (for organic matter, recommended ≥150mg/g), strength (affecting regeneration times, recommended ≥90%), and ash content (affecting effluent quality, recommended ≤8%). Mu Rong's coconut shell activated carbon has passed the Japanese food-grade certification and can meet the stringent requirements for drinking water treatment.

Q2: How does the salt base content of aluminum chloride affect the flocculation effect?
A2: The higher the basicity (60-90%), the greater the charge density of the polyaluminum chloride, and the stronger its bridging adsorption on colloidal particles. When the raw water turbidity of Japanese waterworks is high, it is recommended to choose products with a basicity of 75-85%, which can reduce the dosing amount by over 20% and simultaneously lower the risk of aluminum residue.

Q3: How does Muerong ensure the stability of water treatment material supply?
A3: Mu Rong has established long-term partnerships with high-quality raw material suppliers globally. The coconut shell activated carbon raw materials come from sustainable plantations in Southeast Asia, while the aluminum chloride polymer is produced using aluminum hydroxide from large domestic chemical enterprises. The company maintains a stock of over 500 tons of regular products, capable of meeting urgent order demands from Japanese customers, and supports small-batch trial orders (starting from 10kg).
