市政用水工程

Potable water is divide into two parts: drinking water and non-drinking water. Cobetter various filter series can meet different cities requirement of water quality.

① Pre-RO Filtration——保安过滤

 Function: Stop new particles which are produced in the process or not removed in prefiltration to go into RO system, and protect high pressure pump and RO system. A good Pre-RO filtration system can increase inlet water quality remarkably before go into RO system. RO membrane life time can be extended,chemical regeneration can be reduced, therefore system cost is reduced too. 5um/10um is commonly used.

 

Item Flow Rate Part Number
Option A
≥100m³/h
Option B
<100m³/h
GUF(聚丙烯深层滤芯), 
SGD(高纳污保安滤芯)

 

② Final Sterile Filtration——终端过滤

 Function: Installed on the outlet of city drinking water system. Ensure final sterile filtration process and to remove particles, bacterial and heat source . 0.22um/0.1um is commonly used.
