Silica sand is commonly used as a filter medium in various filtration systems, including water treatment, swimming pool filters, and industrial filtration processes. The specific type of silica sand used for filtering systems is often referred to as filter sand or filter media.
Different filtration systems may have specific requirements for the silica sand used as filter media, varying based on factors such as desired filtration efficiency, flow rate, and the type of contaminants being filtered.
0.45 to 0.55mm range for efficient removal of suspended solids and impurities
Uniform particle size distribution to promote even flow and prevent channeling or clogging
Minimum 90% silica content for good filtration properties
Low levels of iron manganese organic matter and other contaminants
Resistant to degradation during filtration to maintain integrity and prevent excess fines
