Opis:: The paper presents the efficiency of nitrogen removal from wastewater using Brenntaplus VP1 as an external carbon source. The study was conducted during the municipal wastewater treatment process in two independent activated sludge chambers of SBR type. One of the chambers contained glycerol as the source of easily available organic compounds. The study showed that the use of Brenntaplus VP1 as the external carbon source during wastewater treatment resulted in a higher efficiency of nitrogen removal than in the reactor without the external carbon source applied, resulting in low level of the COD value in the treated wastewater. There was a significant acceleration of the denitrification process as compared to the control reactor.

Opis:: The characteristics of the wastewater produced by the tofu industry are high viscosity, slipperiness, and foaming resulting from the continuous fermentation of the tofu bacteria. This made it difficult to reduce the organic content of tofu wastewater, namely biological oxygen demand (BOD5), phosphate (PO4), and Total Nitrogen. A wastewater processor that is designed to handle dense and slippery tofu wastewater is known as a Sequencing Batch Reactor. The impeller is used to create turbulent flow, resulting in more evenly distributed DO, which is difficult to distribute due to the viscous tofu wastewater. The SBR was operated with a hydraulic retention time (HRT) of 24, 36, and 48 hours and an impeller stirring speed of 50, 100, and 150 rpm. The results of the research found that there was an effect on the stirring speed of the impeller and that the low stirring speed of the impeller was not optimal. HRT that was regulated in the SBR cycle has affected the performance of the bacteria. Pseudomonas sp. was found in this study and Bacillus sp., which can degrade up to 90% of phosphate and nitrate.
