VII. Operation Control
1. Standard Operating Conditions
Table VII-1 shows standard operating conditions for “TMR140 Series".
These operating parameters such as MLSS, sludge viscosity, DO (dissolved oxygen
concentration) and pH should be kept in the range of the standard operation conditions given
in Table VII-1 in order to ensure stable operation.
The raw water should be treated with the proper pretreatment facilities before the membrane
modules to remove foreign matters which is harmful to the membrane such as big chunks of
suspended solid or oil.
Please use an alcohol-based antifoaming agent* if necessary.
* Recommended: Kurita Water Industries “Kuriless P.F-663”
The operating conditions may change from this standard conditions, depending on the
characteristics of the sludge, the raw water quality and/or other given operating
circumstances.

Don't use the permeate water for drinking.
Analyze the quality of the permeate water to ensure that the water
quality meets the intended purpose before actual use.
Don't use chemicals, toxic agents, oils or other substances that
can adversely affect activated sludge.
