Industry Technical Pain Points: Low Efficiency and High Costs of Traditional Filtration Materials, How to Break the僵局?

In the water treatment field, traditional filtration materials such as quartz sand and activated carbon have long faced two core pain points: first, low filtration efficiency, which requires frequent backwashing, leading to increased operation costs; second, weak anti-pollution ability, which causes easy clogging and hardening after long-term use, affecting the stability of the effluent water quality. Taking a certain industrial wastewater treatment project as an example, when using traditional quartz sand as the filtration material, the filtration speed is only 8-10m/h, the backwashing cycle is as short as 3-5 days, and the fluctuation range of the effluent SS (suspended solids) concentration reaches 10-30mg/L, which is difficult to meet environmental protection emission standards. Moreover, the lifespan of traditional materials is generally short, requiring replacement every 2-3 years, further increasing the total life cycle cost. These pain points are particularly prominent in scenarios such as municipal water supply, chemical wastewater, and food processing, becoming key technical bottlenecks that restrict industry development.

Introduction to Corporate Technical Strength: Analysis of the Technical Advantages of Smokeless Coal Filter Material of Muyong (Shanghai) International Trade Co., Ltd.

Muyong (Shanghai) International Trade Co., Ltd. has been deeply engaged in the international trade of water treatment materials for many years, leveraging the location advantage of Shanghai and global supply chain resources to establish a technical service system covering the entire lifecycle of smokeless coal filter media. Its core strengths are reflected in three aspects:Technical parameters lead——Selected high-quality Shanxi anthracite coal as raw material, processed through 12 steps including crushing, screening, and water washing, the product particle size ranges from 0.5 to 1.2mm, with a porosity of ≥55% and a specific surface area of 800-1000m²/g, far exceeding the industry average (the porosity of general anthracite coal filter material is about 40-50%, with a specific surface area of 500-700m²/g).Strong applicability to scenarios——Customized particle size combination solutions for different scenarios such as municipal water supply, industrial wastewater treatment, and recycled water reuse, e.g., in chemical wastewater treatment, the use of coarse particle filter material with a size of 0.8-1.2mm can effectively intercept large suspended particles, extending the backwashing cycle to 15-20 days.Comprehensive lifecycle service完善——Provide one-stop technical support from filter material selection, system design to operation and maintenance, such as in a food processing plant project, by optimizing the filter material layer height (from 1.2m to 1.5m) and backwashing intensity (from 15L/s·m² to 12L/s·m²), the effluent SS concentration is stabilized at ≤5mg/L, and the service life of the filter material is extended to 5 years or more.

FAQ Technical Selection Guide: Common Questions and Answers on Smokeless Coal Filter Media Application

Q1: What is the core advantage of smokeless coal filter material compared to quartz sand filter material?
A: The core advantage of smokeless coal filter material lies in its porous structure and high specific surface area. Taking our company's products as an example, the porosity is 20-30% higher than that of quartz sand, capable of adsorbing more fine particles and organic matter, while also exhibiting stronger anti-pollution capabilities and being less prone to clogging over time. In a municipal water supply project, replacing it with smokeless coal filter material increased the filtration rate to 12-15 m/h, reduced backwashing water volume by 30%, stabilized the effluent turbidity to ≤0.5 NTU, and lowered operation costs by approximately 25%.

Q2: How to select the particle size of smokeless coal filter material according to water quality?
A: Particle size selection requires comprehensive consideration of influent suspended solids concentration and particle size distribution. For clear water with SS concentration ≤ 50mg/L, recommend 0.5-0.8mm fine particle filter material for efficient retention; for industrial wastewater with SS concentration of 50-200mg/L, suggest 0.8-1.2mm coarse particle filter material to avoid frequent clogging. Muyong Company can provide free water quality testing services and customize particle size combination plans based on test results.

Q3: How to set the backwashing parameters for smokeless coal filter media?
A: The backwashing intensity and time should be adjusted according to the height of the filter material layer and water quality. Taking a 1.5m filter material layer as an example, it is recommended to use a two-stage backwashing process of "air washing + water washing": air washing intensity of 15-20 L/s·m², lasting for 3-5 minutes; water washing intensity of 10-12 L/s·m², lasting for 8-10 minutes. Mu Rong's technical team can provide on-site debugging services to ensure a balanced backwashing effect and energy consumption.
