Quartz Sand

The first and most critical stage of industrial and commercial water treatment processes is the physical purification of water. Silt, rust, clay, sand, and other large particles naturally found in well, municipal, or surface water not only cloud the water but also cause serious damage to plumbing systems and machinery. Quartz sand minerals are the most natural, common, and reliable filtration media for capturing these visible or suspended impurities in water.

These minerals, which naturally contain a high silica (SiO₂) content and are extremely resistant to wear, are arranged in specific layers within treatment tanks to form an excellent mechanical filtration barrier. Acting solely as a physical filter without altering the water’s chemical composition, quartz sand is the cornerstone of water treatment systems.

Water treatment sand, placed inside multi-layer (multimedia) filter tanks in various grain sizes, performs two basic physical treatment processes:

As water filters down from the top layer of the tank to the lower layers, it passes through beds of sand and gravel of various sizes, such as 0.5–1.0 mm, 1–2 mm, or 3–5 mm. Coarse particles and sediment that cause turbidity in the water become physically trapped within these beds. The result is clear, sediment-free, clean water at the outlet.

The quartz bed, which acts as a sediment filter, prevents coarse contaminants from clogging much more sensitive and expensive equipment in your facility, such as activated carbon, water softening resin, or reverse osmosis membranes. This helps extend the efficiency and service life of the entire water treatment system.

A properly sized sand filter provides significant operational benefits to mineral processing plants:

1. Natural and Eco-Friendly: Contains no chemical additives; it creates only a physical barrier.
2. Long-Lasting Performance: Thanks to its silica structure, it does not dissolve or crumble in water.
3. Easy Cleaning (Backwashing): Trapped mud and sediment are easily flushed into the drain via the system’s automatic backwashing process, allowing the sand bed to regenerate itself.

Achieving high efficiency in sand filters is not simply a matter of filling the tank with sand. Determining which grain size should be used at what depth—from the support gravel at the bottom to the fine sand at the top—based on the water flow rate and pollution load requires precise hydraulic engineering calculations. With over 30 years of deep-rooted field experience in the water treatment industry, we design the most appropriate layer configuration (multimedia filtration) for your facility.

The pressure-resistant sizing of filter tanks, the proper filling of mineral media, and the adjustment of the backwash automation speed to clean the sand are meticulously carried out by our professional team. Through our supply of the highest-quality media and periodic technical service, we ensure your process is always protected against physical contaminants.
