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 the critical role of activated carbon in completely adsorbing residual chlorine, which effectively prevents oxidative damage to downstream reverse osmosis membranes or ion exchange resins, thereby ensuring the safety and service life of the entire desalination system.

The Sand-Carbon Filtration System  has demonstrated exceptional application value and adaptability across various industrial and civilian sectors.The Pretreatment System features excellent product water quality, strong resistance to impact load, water and electricity saving, low operating costs, and a long service life. In industrial purified water preparation, it serves as a front-end pretreatment unit for reverse osmosis, electrodialysis, and ion exchange systems, providing reliable influent guarantee for deep desalination processes.In addition, it also serves the fine filtration and ingredient water purification in the food and beverage industry, circulating cooling water treatment in power and chemical enterprises, as well as circulating water for swimming pools and water purification systems for livestock farms, meeting the stringent requirements for pretreatment water quality in high-standard industries such as electronics and semiconductors, and daily chemicals.

 

We also have other water treatment equipments, such as Reverse Osmosis System and Ultrapure Water System.
