2. Operation and Maintenance
Don't use permeated water for drinking.
Before discharging the treated water to the environment or reusing
it, make sure to analyze its quality and confirm that the water
quality meets the intended purpose.
Don't burn the membranes without appropriate facilities since
harmful Hydrogen fluoride (HF) gas is generated at burning.
When dispose membranes, please apply a service of a qualified
waste disposing company.
When the clean water operation, charging clean water to the
membrane submerged tank with the air discharge valve open to
release air from the elements. After charging water, close the air
discharge valve.
Don’t use the ground water, which contains considerable amount
of iron, manganese, calcium or silica, for the clean water operation
as it may cause the clogging of the membrane.
Don't continue the clean water operation unnecessarily.
A long-time filtration of clean water tends to cause the clogging.
Once the membrane gets wet, keep it wet. If the wet membrane is
dried up again, the permeability of the membrane might be
decreased seriously.
When feeding the seeding sludge, be sure to remove foreign
substances from it with the screen (with openings of 5mm or
under).
Don't do the filtration operation without supplying the scouring air in
a right way, or the membrane will be clogged severely.
Don't put in the activated sludge liquid chemicals, toxic agents, oils
or other substances that may adversely affect activated sludge.
ABS supporting panel may get chemical cracks by some organic
solvent, such as alcohols and oils, and some synthetic detergents. So
don't make ABS panel contact such materials.
Please avoid abrupt changes of operating conditions, especially
pH, temperature and the suction pressure of the membrane even
within the range of the standard operating conditions (Table VII-1).
Please replace the renewal parts periodically or when the
deterioration is detected at the inspection.
