Filter and Treatment Sand
Filter and treatment sand is a high-purity filtration material used in water treatment systems, produced from natural quartz or silica minerals. Manufactured in accordance with the TS EN 12904 standard, our filter silica sand products are produced to meet the chemical and physical safety criteria required for filter materials used in drinking water treatment systems.
Sand filters are high-efficiency units designed to remove water-insoluble particles, suspended solids of various sizes and turbidity. The quartz sands used in treatment plants show high abrasion resistance, are durable against mechanical damage, and undergo no dissolution or mass loss in acid tests.
Both rapid and slow sand filter systems are used in water treatment plants. Rapid sand filter systems generally use filter sand in the 0,800–1,200 mm range and are equipped with nozzle and backwash systems. In slow sand filter systems, filter sand of 0,300–0,500 mm is laid to a height of approximately 1 metre over support layers of 15–25 mm gravel, 5–15 mm gravel, 3–5 mm and 1–3 mm.
The correct selection of filter materials directly affects the quality of the treated water. In multi-layer filtration systems, filter sand, filter gravel, filter anthracite and filter garnet are used together to achieve maximum filtration efficiency.
