Change of electromagnetic field has a great influence on conductivity and congulation performance of PFS dissolved liquid. It can be turned by alternating electromagnetic: under normal condition

the conductivity value of PFS dissolved liquid treated by alternating electromagnetic increased 14%

stability improved double

effluent turbidity improvrd double

dosage saved 2 times; Clear positive correlation was shown between them

Between the conductivity and hydrolysis performance exist clear positive correlation. Both of them displayed V shape in voltage range of 0~220v

current range of 0~1.2A

frequency range of 0~200

200~400Hz

magnetizingtime range of 0~180s

Voltage

current

high frequency

band frequency and magnetization time change

electric charge neutralization of PFS is a leading ability

at low-band frequency

adsorption and bridging is a leading ability

the best parameters for voltage is 100v

current is 0.7A

frequency is 150Hz

magnetizingtime is 60s.
