Quartz Sand Filtration and Carbon Sand Filtration

  The Sand-Carbon Filtration System serves as the core component in modern water treatment pretreatment systems, employing a dual mechanism of physical retention by quartz sand and chemical adsorption by activated carbon to achieve efficient purification of raw water.During the physical filtration stage, the water flow passes through the Quartz Sand Filtration layer from top to bottom. Suspended solids, silt, colloids, and large particulate impurities in the water are effectively intercepted due to screening and adhesion effects, thereby significantly reducing the effluent turbidity.Subsequently, the initially filtered water enters the activated carbon layer. Relying on its massive specific surface area and developed microporous structure, as well as the chemical adsorption characteristics of oxygen-containing functional groups on its surface, the activated carbon effectively removes organic pollutants, color, odor, and residual chlorine from the water.Of particular significance is th…
