Multigrade Filters: Superior Pre-Filtration for Clear Water

A Multigrade Filter (MGF) is a highly efficient pre-filtration system that works on the principle of depth filtration. It uses a graded bed of coarse and fine media, typically a mixture of sand, gravel, and pebbles in a fixed proportion. This arrangement creates a filter bed with varying pore sizes, allowing for the effective trapping of a wide range of physical impurities, including suspended solids, mud, silt, and other particulate matter.

How Our MGF Systems Work

Unlike conventional single-media filters, our multigrade filters operate at a significantly higher flow rate. The multi-layered design ensures that larger particles are trapped in the top, coarser layers of media, while the finer layers below capture smaller particles. This staged filtration process leads to:

• High Dirt-Holding Capacity: The entire depth of the filter bed is used for filtration, extending the time between backwash cycles.

• Reduced Pressure Drop: The efficient flow through the graded media minimizes pressure loss, saving energy and improving overall system performance.

• Effective Turbidity Removal: Our filters consistently reduce turbidity and Total Suspended Solids (TSS) from the water, making it clearer and more suitable for downstream processes.
