•

Theory
Application/Function in DI System
Operation

After this training:

•
•
•

Know the theory of main units
Understand the function of units in DI system
Understand the possible causes of abnormal performance Daily Operation
To take care of the system

•
•
•
•

To watch
To listen
To smell
To feel

Why???

•
•
•
•

To find out problem on time, minimize loss
To prevent problem happening
Data collection for analysis
“It was” can’t guarantee “it will be”!

Daily Operation
Our goal:

•

To maintain water treatment system at tip-top condition in order to produce pure water for manufacturing process

•

To apply best known methods in process to optimize unit cost of water purification process

•

To minimize system incident which will cause supply interruption or system down time

•

To eliminate ESH issue

Water Resources
The volume of all water on Earth is about 1,360,000,000 km³
(326,000,000 mi³).
