The paper is devoted to the study of small wastewatertreatment plants, in particular the study of wastewater treatment processes with the wastewater with low concentration of organic contaminations entering treatment plants. The primary goal of the study is to select the reactor operation mode to ensure the deep biological treatment quality of trea...

... order to optimize the column performance as a Sequencing Batch Reactor, time relays were used, which switched on and off the aerator, stirrers in accordance with the specified time, and created conditions for the activated sludge sedimentation. The laboratory-scale plant operation diagram is shown in Fig. 1. Then there is a photo of the plant in Fig. 2. The work was carried out with the use of artificially composed peptone-based waste liquid. The contaminations concentrations were closest to those existing in the actual waste liquid. In the course of the experiment, the concentrations of certain substances and the hydraulic load on the plant changed depending on the task assigned. ...

This paper presents an assessment of the start-up performance of aerobic granular sludge (AGS) for the treatment of low-strength (chemical oxygen demand, COD < 200 mg/L) domestic wastewater by the application of a diatomite carrier. The feasibility was evaluated in terms of the start-up period and stability of the aerobic granules as well as COD an...
Sequencing batch reactors (SBRs) are devices widely used in wastewater treatment, chemical engineering, and other areas. They allow for the sedimentation and compression of solid particles of biomass simultaneously with biochemical reactions with nutrients dissolved in the liquid. The kinetics of these reactions may be given by one of the establish...
