Comparative Analysis of the Effectiveness of Regulation of Aeration Depending on the Quantitative Characteristics of Treated Sewage Water

Abstract

Monitoring of work of the aeration tanks of operating town treatment plants is done. Based on the obtained results a conclusion has been drawn that sewage water is improperly treated from ammonium nitrogen. The velocity of the aeration process, depending on the concentration of dissolved oxygen and ammonium nitrogen, is investigated. The obtained investigation data became the basis for modeling the aeration process in industrial conditions depending on the required initial concentration of ammonium nitrogen.

Cavitation-Reagent Technology for Water Purification of Pools and Water Parks

“…The working chamber (9) is connected to the loading (6) and the unloading (14) chambers with the possibility of relative displacements through the flexible grooves (8 and 12). The ring-shaped anchor (10) made of sheet iron is fixed on the working chamber (9). The chamber and the anchor through the brackets (2) and the cylindrical elastic rods (5) are connected with reactive masses (11), which are fixed on the pipes of loading and unloading chambers.…”

“…At best, these substances are used in other industries, for instance, as complex fertilizers of prolonged action (Tulaydan et al 2017). The biological methods (this technology is typical of municipal waste water purification) produced a large amount of biological sludge, which has already created considerable environmental pollution in Ukraine and in a number of other countries (Malovanyy M. et al 2016, Malovanyy A. et al 2014). Therefore, the purification methods that do not form secondary waste are of special interest.…”

Analysis of environmental safety of recreational territories of mountain ecosystems and development of technical measures for its stabilization

“…The general tendency in minimization of the impact of anthropogenic activity on NNPs is the use of renewable energy sources [24] to prevent pollution of the hydrosphere. The sources are natural sorbents [25], membrane methods [26] and biological natural purification methods [27].…”

Solar Water Purification System Design: Application Study in Lake Taihu, China

“…The polluted sediment is an important factor for the formation of black water aggregation [31]. Significant energy input is a necessity for aeration of wastewater and is often one of the biggest constituents of the total energy requirements of a purification plant [32].…”
