In the pursuit of cleaner water, advanced filtration techniques are often employed. Multi-media filtration, a process that utilizes layers of different granular materials, is particularly effective. Among these materials, anthracite plays a critical role, offering distinct advantages when combined with other media like sand. NINGBO INNO PHARMCHEM CO.,LTD. highlights the benefits of using anthracite in optimizing water filtration systems.

Multi-media filters are designed to leverage the unique filtering characteristics of different materials to achieve superior water quality. Typically, these systems consist of an anthracite layer at the top, followed by sand, and often a layer of gravel at the bottom. The anthracite, with its coarser granulation and angular shape, acts as the initial filter, capturing larger suspended solids and turbidity. Its ability to penetrate deeper into the filter bed, compared to sand, means it can hold more solids without premature clogging.

The strategic placement of anthracite in a multi-media system is key to its performance. Its lower specific gravity allows it to remain above the denser sand layer during backwashing, ensuring that the layered structure is maintained. This layering effectively utilizes the entire filter bed for solids retention, leading to significantly longer filter runs than single-media filters. Longer filter runs translate directly to less frequent backwashing, which in turn reduces water wastage and the consumption of treated water for cleaning cycles.

Moreover, the angularity of anthracite particles promotes more effective backwashing. The agitation created by these particles during the backwash process helps to dislodge captured solids more efficiently, ensuring that the media is thoroughly cleaned and ready for the next filtration cycle. This improved cleaning efficiency contributes to the longevity of the filter media and the overall system.

For industrial facilities and municipal water treatment plants, adopting multi-media filtration with anthracite can lead to substantial operational benefits. It reduces the frequency of maintenance, lowers energy consumption due to decreased head loss, and consistently delivers higher quality filtered water.
