FIELD: technological processes, filters. ^ SUBSTANCE: invention is intended for treatment of sewage waters. Installation comprises the following components: reservoir N with liquid, the first surface groove 2a with overflow device 2a1, outlet unit P for floating impurities and the second surface groove 2c for removal of cleaned liquid. Floating impurities in continuous flow are poured in two subsequent stages: first in primary volume I, then - in secondary volume II. Floating impurities from primary volume I into secondary volume II are poured in controlled manner by means of liquid level h1 control in primary volume by unit 2a2 for flow balancing and/or by means of control device application that is installed in wall separating primary volume I and secondary volume II. It helps to separate floating impurities from liquid phase and their removal from reservoir. Cleaned water is removed by means of the second surface groove 2c. ^ EFFECT: simplification of device design, improvement of process of floating impurities separation from liquid phase. ^ 7 cl, 7 dwg |
