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.

A process for the purification of industrial waste water containing solid particles comprising introducing said waste water into a settling tank with agitation wherein a portion of the solid particles in said waste water form flocs and settle in the form of sludge and clarified waste water which contains the remainder of said solid particles which overflow the settling tank, dividing said clarified waste water into several streams, conveying each of said several streams to respective lower portions of spaces between the plates of a first inclined plate pack wherein the solid particles coagulate in the space between the plates, and the coagulated particles settle on the plates and slide to the bottom thereof and then into the bottom of a receiving basin and are removed therefrom, and clarified water rises between the plates and is taken off through an overflow at the top.
