Abstract: The current scenario requires treatment systems with high efciency, easy operation and low cost. The solid?liquid separation process as a pre-treatment of swine manure is an efcient strategy improving the wastewater management and treatment. In this sense, the aim of this study was to establish for the frst time a condition in which swine manure treatment could be successfully performed using a simple solid-liquid separation, combined with nitrifcation and denitrifcation process in a modifed Ludzack?Ettinger system. The solids separation was done with a brush-roller screen (2 mm mesh) followed by a settling unit. The nitrogen removal unit was composed of a modifed Ludzack?Ettinger process, operated in three phases, according to diferent sedimentation times in the solid?liquid separation process. The modifed Ludzack?Ettinger system showed good performance for treatment of swine wastewater with total suspend solids concentration higher than 14 g L−1, reaching removal efciency of 88.3% for nitrogen and 86.3% for total organic carbon removal. The results obtained in this study confrm that it is possible to operate the modifed Ludzack?Ettinger system at high total solids concentration using a simple solid?liquid separation process keeping a high nitrogen removal efciency. |
