Cationic polyacrylamide usage and dosage
When cationic polyacrylamide is used
for sludge dewatering,
the recommended concentration of cationic polyacrylamide
is 2 parts per thousand.
Different industries and different water quality
are tested to determine the dosage.
Before using cationic polyacrylamide,
sample experiments are required
to determine the best ratio.
It is recommended to take a 100 milliliter sewage sample
and add 0.5 milliliter of
cationic polyacrylamide solution each time.
Stir constantly and observe,
check the sewage flocculation effect,
flocculation speed, supernatant condition,
sedimentation effect, etc.,
to determine the best dosage.
Under normal circumstances,
the dosage of solid dry powder polyacrylamide
in sewage is 10-20g/per ton
Cationic polyacrylamide is mainly used
in paper mills,
wastewater treatment plants,
chemical wastewater,
coal washing plants, etc.
