The Impact of an Ultrasonic Field on the Efficiency of Coke Wastewater Treatment in a Sequencing Batch Reactor

The growing production of coke and, consequently, wastewater is a significant problem for the environment. Coke wastewater, because it contains high amounts toxic substances, classified as an extremely hazardous industrial wastewater. treatment such requires combination advanced physicochemical and biological methods. aim research was to investigate effectiveness application ultrasonic disintegration in sequencing batch reactor (SBR). tests were conducted two stages, wherein first stage involved determining most favorable sonication conditions, that is, time amplitude. authors used following amplitudes: 31 µm; 61.5 92 123 µm times: 120 s; 240 480 960 s. second focused on treating SBRs (Reactor A—a proportion mixture: 5%, 10%, 20%; B—sonicated 20%). efficiency process determined based rate removal selected parameters: chemical oxygen demand (COD), total organic carbon (TOC), inorganic (IC), ammoniacal nitrogen (N-NH4), (TN), course pH changes. study revealed increased biodegradability reduced its toxicity. use preliminary before improved degree tested parameters by approximately 10%. volumetric ratio mixture had greatest impact obtained results. ultrasound field allows be executed with addition exceeding In addition, found order increase efficiency, one should optimize individual phases SBR pollution load.
