Our quartz frits are high-purity sintered filter media, meticulously engineered for effective filtration and separation. Utilizing quartz sand as the primary medium, these porous discs exhibit excellent mechanical strength and chemical stability. They feature a negative surface charge, enabling the adsorption of positively charged suspended solids like silt, algae, and bacteria, achieving superior water purification. Available in various porosity grades (G00 to G5, ranging from 5 to 550 microns) and customizable dimensions (thickness 1.5-300mm, diameter 2-500mm), our quartz filters are ideal for demanding laboratory, industrial, and environmental applications.

How it works
A quartz sand filter utilizes quartz sand as its filtration medium. Water flows through the quartz sand layer under gravity or pressure. Quartz sand possesses good mechanical strength and chemical stability, and its surface carries a negative charge, enabling it to adsorb positively charged suspended solids in water, such as silt, algae, and bacteria. Larger particles are intercepted at the surface of the sand layer, while smaller particles gradually penetrate into the sand layer, eventually being adsorbed and retained by the quartz sand, thus achieving water purification.
