ABSTRACT:
A process and apparatus for the purification of industrial waste water containing solid particles. The apparatus contains at least two treatment sections. The first treatment section is a settling tank containing an agitation means, preferably an inclined deflector plate against which the waste water is directed to form a rolling wave and causing solid particles to coagulate and settle. The partially cleaned waste water overflow from the first stage is conveyed to the lower portions of the second stage into spaces between inclined plates which form an inclined plate pack clarifier. The solid particles are taken off from the bottom of the second treatment section, and clarified water is taken off from the top.
