Abstract
Čiščenje odpadne vode postaja vse bolj ključnega pomena po vsem svetu. Kvaliteta čiščenja in energetska učinkovitost procesa sta močno odvisni od izbire komponent in delovnih strojev. Izbira delovnih strojev se nanaša na kompresorje in puhala različnih tipov. Ključnega pomena za učinkovito delovanje sistema je izkoristek vsakega posameznega delovnega stroja. Zato smo določili specifična območja delovanja za vsak delovni stroj in upoštevali porabo energije med njihovim delovanjem, da bi zagotovili najvišjo energetsko učinkovitost. Poznavanje območja, v katerem delovni stroji delujejo ter kakšne so pri tem vrednosti tlaka in pretoka, nam omogoča pravilno izbiro senzorjev in zagotavlja njihovo optimalno delovanje. Poleg tega smo identificirali ključne dejavnike, ki vplivajo na sistem in delovanje posameznega delovnega stroja, kar nam omogoča boljše razumevanje in optimizacijo celotnega sistema čiščenja odpadne vode. Rezultat naloge kaže na to, da je najbolj primeren tip delovnega stroja za aerizacijo zraka Rootsovo puhalo. Uporaba dvostopenjskega centrifugalnega puhala je prav tako ustrezna. Spiralni in batni kompresorji pa imajo premajhen pretok, saj so pri dani moči praviloma konstruirani za višje tlake.

Title:Designing a system for measuring characteristics of compressors intended for aeration
Abstract:
Wastewater treatment is becoming increasingly vital worldwide. The quality of purification and the energy efficiency of the process heavily depend on the choice of components and operating machines. The selection of operating machines pertains to compressors and blowers of various types. The efficiency of each individual operating machine is crucial for the effective operation of the system. Therefore, we have defined specific operating ranges for each operating machine and considered energy consumption during their operation to ensure the highest energy efficiency. Understanding the area in which the industrial machines operate and the values of pressure and flow is crucial for making the correct sensor selection and ensuring their optimal performance. Furthermore, we have identified key factors influencing the system and the operation of each individual machine, which allows for a better understanding and optimization of the entire wastewater treatment system. The result of the task indicates that the most suitable type of machine for air aeration is a Roots blower. The use of a two-stage centrifugal blower is also appropriate. However, spiral and piston compressors have insufficient flow, as they are generally designed for higher pressures given the same power.

Keywords:aeration, compressor/blower, operation area, efficiency, sensors
