Abstract

PURPOSE: To enable circulating use of washing liquid and to decrease the amount of damping, by removing coarse grain at the first settling tank and overflowing to the second settling tank and moreover, introducing to the third settling tank passing through a high gradient magnetic filter which removes minute particles containing Fe.
CONSTITUTION: Washing liquid from the washing liquid tank 1 is introduced to the descent part 2a of the first settling tank 2 and particles of 30 microns or more, are precipitated and removed by the usual method and then, the above liquid is overflowed from the ascent part 2b to the second settling tank 3, at the purification of washing liquid for electrolytic washing equipment of the surface of steel material, such as strip etc. Next, the above liquid is sent to the third settling tank 4 through the high gradient magnetic filter 5. At this time, partices of grain diameter of 30 microns or less containing Fe, are removed nearly perfect. Purified washing liquid able to use circulatively, can be obtained because the precipitation and removal of removal of particles having the grain diameter of 30 microns or less, is carried out in the second settling tank 3 and the third settling tank 4.
