Silica sand is used frequently in water filtration systems. The chemical compound silicon dioxide is also known as silica sand. Filter silica sand consists of hard, durable, and dense grains of predominantly siliceous material that will resist degradation during handling and use.

Silica sand is an extremely effective filter media because of its ability to hold back precipitates containing impurities. Filter sand size, angularity and hardness are the important filter sand characteristics to ensure proper filtering.
