Silex

Silex is used to filter and clean portable water filters and pool filters and sewage treatment plants. It is a highly effective filter media as it hold back precipitates containing impurities. Filter sand size, angularity and hardness are the important filter media sand characteristics to ensure proper filtering.Silex, also known as silica sand or quartz sand, is a naturally occurring material composed primarily of silicon dioxide (SiO2) crystals.Silex consists mainly of silica (SiO2) in the form of small granules or grains. It is one of the most abundant minerals on Earth and can be found in various geological formations, including sandstone, quartzite, and beach deposits. Silex typically has a white to light gray color, although it can also occur in shades of pink, brown, or black depending on impurities and mineral content. It is characterized by its hardness, high silica content, and resistance to weathering and erosion.
