Mobile Ceramic Membrane Filtration Equipment

Technology / Service Summary

Mobile water purification system using ceramic membrane loaded onto a truck. It enables filtration of high turbidity raw water available in the event of disaster. No chemical to prevent deterioration in quality is required while storing ceramic membranes in a long period of time. Operation has no problem at places where there is no power source available, because a generator stands by in a truck.


Filtration of raw water and supply of potable water to rural areas where there is no water purification plant as well as to areas suffering so much inconveniences due to a disaster such as flood, etc.


The characteristics of the system are as follows.
1)Ceramic membrane which has a longer life span over 15 years, can filtrate high turbidity raw water to remove protozoa such as cryptosporidium and bacteria such as E coli.
2)No chemical is required while storing ceramic membranes in a long period of time.
3)No sedimentation basin is required, therefore, configuration of the system becomes simple. The O&M is also simple because replacement of membrane does not happen for such a longer period of time.   


The system can filtrate high turbidity raw water to supply the following volume of drinking water according to the number of membrane elements used.
One element system (ground water:1~4 m3/hr., surface water:1~2.5 m3/hr.)
Two elements system(ground water:2~8 m3/hr., surface water:2~5 m3/hr.)
Four elements system(ground water:4~16 m3/hr., surface water:4~10 m3/hr.)
