This article presents an analysis of results of the research on the turbidity and oxygen content in water after the pipe aerator. Turbidity and oxygen content in water, measurements was conducted in conditions of technical exploitation of water treatment plant. The research embraced the pipe aerator with the Białecki rings which was made of stainless steel about the diameter of 12 mm. It was found that together with the growth of the flow of air at the given flow of water, the content of oxygen in water and her turbidity is increasing proportionally. However together with the growth of the flow of water at the given flow of air, the content of oxygen in water and her turbidity is decreasing.
