The effectiveness of any water filtration system hinges on the quality and specific properties of the filter media employed. At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on providing anthracite filter media that not only meets but exceeds industry expectations. Understanding the key specifications of this remarkable medium is crucial for optimizing its performance in various water treatment applications.

Effective Size and Uniformity Coefficient: The 'effective size' refers to the average particle diameter in a filter medium, while the 'uniformity coefficient' indicates the consistency of particle sizes within the sample. Anthracite filter media is typically characterized by a low uniformity coefficient (often less than 2). This means the particles are more uniformly sized, which is critical for creating a consistent filter bed. A low uniformity coefficient promotes even flow distribution, enhances solids retention, and reduces the likelihood of filter bed stratification, leading to more predictable and reliable filtration results.

Hardness and Durability: Anthracite is known for its high hardness, typically measured on the Mohs scale (around 3.0-3.8). This inherent hardness contributes to its exceptional durability, allowing it to withstand the abrasive forces of backwashing and the chemical stresses within a filter system. This durability translates to a longer service life for the media, reducing replacement frequency and associated costs.

Specific Gravity and Density: Anthracite has a specific gravity of approximately 1.65 and a bulk density of around 50-56 lbs/ft³. These properties are vital, especially in multi-media filtration systems. Its relatively lower density compared to sand allows it to hydraulically classify on top of the sand layer during backwashing, creating an effective pre-filtration layer that captures larger particles and improves the overall efficiency of the filter bed.

Chemical Stability: A key attribute of anthracite filter media is its stable chemical nature. It remains insoluble in ordinary acidic, alkaline, and neutral water, ensuring that it does not leach harmful substances into the treated water. This chemical inertness is crucial for applications involving potable water and sensitive industrial processes.

By understanding these technical specifications, water treatment professionals can better appreciate the value that high-quality anthracite filter media from NINGBO INNO PHARMCHEM CO.,LTD. brings to their systems. We are committed to providing media that is meticulously processed to ensure these critical properties, empowering our clients to achieve optimal water purity and operational efficiency.
