PURPOSE:To efficiently and sufficiently separate and remove a non-magnetic suspended substance, in performing magnetic separation by adding a magnetic material and a flocculant in a liquid containing a non-magnetic suspended substance, by adding a magnetic material uniformly dispersed by ultrasonic waves. CONSTITUTION:Raw water containing a non-magnetic suspended substance is sent to an arranged pipe by a pump 14 while a dispersion 71 having magnetite powder particles uniformly dispersed therein by an ultrasonic oscillator 61 and a dilute solution 42 of a flocculant subjected to stirring treatment by a blade type stirrer 23 are added on the way of the arranged pipe by pumps 15, 16. In the next step, this liquid mixture is treated with an electromagnetic filter 52 to obtain treating water. |
