[Algal inactivation and removal by pulsed magnetic field with varying frequency].
The paper studied the algal inactivation and removal by pulsed magnetic field with varying frequency. The results indicated that algae could be inactivated and killed by the magnetic treatment for the circulating water sample. When the accumulated resident time reached 6 minutes, the algae became to die with the mortality of 94%. If the resident time were 10 minutes, the algal mortality would be more than 96%. The treated algae didn't grow within 120 hours, which indicated that the "magnetic memory time" can reach 120 hours. For the static sample in magnetic field, the inhibition effect became to do the work after 1 hour. Different treatment methods brought about different results. It was more propitious to inactivate the algae for circulating sample.
