ABSTRACT

The paper presents and analyses the results of the research on hydraulic resistance in pipe aerators for waters from Tertiary and Quaternary periods, under conditions of technical exploitation of water treatment plant. Hydraulic resistance investigation was conducted in concurrent pipe aerators filled with the Białecki rings of 12 and 25 mm diameters. The research methodology comprised of measuring hydraulic resistance in the case of clean rings (after the start of water treatment plant operation) and in the case of silted ones (after some two years of water treatment plant operation). On the basis of that researches, some hydraulic phenomena occurring in pipe aerators filled with the Białecki rings were recognized and exploitation rules for this kind of aerators were established.

Key words: water, pipe aerator, water treatment plant, hydraulic resistance, Bialecki rings.
