Xiamen quartz sand [factory outlets] Zhangzhou quartz sand / quartz sand in Quanzhou / Fujian quartz sand Australia Springs 



 Quartz sand filter will need to filter the water through the pump boost (about 0.6MPa) through the filter layer of filtering purposes, also known as a pressure filter. 

 According to the water can be divided into single-flow mechanical filter and dual mechanical filter. The former flow direction from top to bottom, which is the upper and lower ends of the water, 
 Central water. Filter loading, can be divided into single-layer media mechanical filters and double-layer (multilayer) mechanical filter. 

 Quartz sand filter can be used for the ion exchange process to soften the desalination pretreatment, reverse osmosis pre-filter device; life, industrial sewage, waste water over 
 Filter handling and less demanding of water quality coarse filtration of industrial water supply and swimming pool water filtration, filter size specifications as the water quality requirements for softening and demineralization 
 Pretreatment of quartz sand, 0.5 ~ 1.0mm, 1.2 ~ 1.6mm anthracite. 





 Quartz sand filter tube body, compaction arranged by size from the bottom to the different size of the filter. When the filter layer down on the water since the water contains 


 The suspended material to flow into the tiny pores of the upper filter by adsorption and mechanical role of spoiler, suspended solids filter surface interception. Same time, these 


 "Overlap" and "bridging" role between the suspended solids are retained in the surface of the filter layer to form a thin film, continue to occur filtering effect. This is the so-called 


 Filter surface of the membrane filtration effect. The filtering effect of the film is not only the surface exists, and when this interception of the flow into the intermediate filter layer. 


 Different from the surface of the membrane filtration effects, this intermediate Interception called penetration function as a filter. 

 In addition, so the water filter between each other tightly, and another curved pore formation by suspended solids particles through the filter media particles, there are more opportunities and time with the filter surface collide with each other and contact suspended solids of red The filter media particle surface flocculation mutual adhesion, exposure coagulation. 

 The working principle of the filter penetration by membrane filtration - filtration - contact coagulation process, so that the water quality purification.
