Sažetak
This paper gives wastewater aeration analysis by implementing the “ plunging water jet” aerators. To clarify the characteristics of such aeration process, physical model was designed consisting of: inlet chamber with constant water surface level and jet-designed outlet (nozzles), and receiving pool representing biological reactor. Variational parameters were number of nozzles, their effective diameter and angle, as well as flow and velocity of resulting water jets. Besides measurements of hydraulic parameters, the aim was to determine dissolved oxygen enrichment in biological reactor, depending on specific nozzle parameters. One of the goals was to find the optimal combination of such parameters that would result in maximum aeration rate. The study was carried out using the potable water from public water supply system. Based on resulting aeration efficiency it is possible to estimate the possibility and adequacy of plunging water jet aerators application within the specific site conditions. The final purpose was to reduce the total construction, operational and maintenance costs of wastewater treatment plants, concurrently increasing their treatment efficiency.
