Durable graded silica gravel for water treatment, providing a stable support bed for filtration systems with excellent chemical resistance and flow distribution.
Graded silica gravel is a durable and chemically stable filtration media widely used in water treatment systems. Acting as a support bed beneath sand, resins, or other filtration media, silica gravel enhances water flow distribution and prevents fine media from escaping into the outlet stream. Its hardness, uniform particle size, and low acid solubility make it an essential component for both municipal and industrial water treatment applications.
