Quartz sand filter |
| |
 Quartz sand is a kind of filter which is most widely used and has largest amount in China,it is apply in single,double quick filter and high purity water treatment as supporting layer for industrial. The quartz sand which our company produced,with natural quartz mine as raw material,produced through mining, broken, washing, sieving,etc process (High purity quartz sand by acid), appearance is white crystal with polyhedral or globular shape,has no impurities,high mechanical strength, chemical performance stable,strong Sewage Interception capacity, also can use long cycle,with good economic. |

Anthracite filter used Shanxi high quality carbon as raw material,produced through selection, crushing, screening and other process.It has uniform size, good glossiness, compression wear, high mechanical strength, long life cycle.And practical apply to general acid and alkaline water purification.Also it is the necessary purify material for double, three filter chamber, the technical indicators have reached and exceeded the Ministry of Construction (CJ/T44-1999) standards. 
Magnetite filter applied to a large resistance to water distribution pipe system, usually associated with quartz sand and anthracite filter media, is a necessary filter material in the use of three-layer filter,it has the application of good ability to improve the supporting layer and the water distribution system ,has high strength, filter fast, and when backwashing not easy in mixed layer. In addition, it has good effect on remove iron, manganese and fluorine.
Manganese sand filter with manganese ore as raw material,is produced through crushing, screening and other processes. The appearance of rough brown or light gray, commonly used in drinking water’s filter devices to remove iron, manganese , water treatment effect is very good. (Note: MnO2 ≥ 35% either removing iron, but also manganese, MnO2 ≤ 30%,can only be used for remove iron from ground water).
