Silica sand for water filtration

Natural silica sand has a sub-angular to a rounded shape, making them an ideal filtration media to capture suspended solids in water. Due to high silica content, sand is durable and hard-wearing, allowing it to be graded precisely to facilitate efficient filtering. These grades include 16/30, 8/16, 6/14, and 14/25, 20/40,18/8, 2/4,3/6, 6/13, 13
