VII. Chemical Cleaning
The chemical cleaning should be carried out to remove foulants accumulated in the membrane
pores or sticking to the membrane surface.
Carry out the chemical cleaning before the trans-
membrane pressure rises to 200 kPa (29.0 psi), or the
module filtration performance could be reduced
significantly.
Follow the instruction described in this manual when you
carry out the chemical cleaning. If you use the
unacceptable chemicals or perform the cleaning altered
from the recommended procedure, the membrane could
be seriously damaged.
Pay full attention when handling chemicals and be sure
to wear the safety gears such as glasses and gloves.
The chemicals used for the chemical cleaning are
harmful to people. If chemicals directly contact your
skin, your eyes, or other body parts, take the
appropriate treatment as stated in its SDS.
Do not mix sodium hypochlorite with acid. Such mixture
generates toxic chlorine gas.
Stop operations when any instrumental anomalies
occur, or any sign of anomalies are observed.
