Multigrade Sand Filter
Overview
A Multi Grade Filter (MGF) is a high-performance depth filtration system designed to remove suspended solids, turbidity, colloidal matter, and fine particulate impurities from water. The filter contains multiple layers of specially graded filtration media with varying particle sizes, enabling superior filtration efficiency, higher dirt-holding capacity, and longer filtration cycles compared to conventional filters.
