The scope of works includes reconstruction and extension of the existing sanitary sewage treatment plant operating in the Autothermal Thermofilic Sludge Stabilisation technology. The technology of the existing sewage treatment plant in Jarosławiec with a capacity of Q=2 500 m /d was adopted based on the process of low-loaded activated sludge working according to the SBR (Seqence Batch Reactors) batch treatment method with a batch supply from a retention tank, according to the system with a fixed filling volume. 3. As part of the reconstruction and expansion of the sewage treatment plant, the existing facilities should be used: a social and technical building, the SBR reactor chamber, the raw sewage and supernatant water pumping station, the barrel-wagon parking plate, the sedimentary lagoons and the construction of new facilities: SBR reactor chamber, retention tank, thickened sludge storage chamber, thermophilic stabilization chambers I and IIo, stabilized sludge storage chamber, sludge pump chamber, odour neutralisation system, sludge dewatering building, sludge shed, transformer station, power generator of min 250kVA, sewerage station. As part of the task, the accompanying infrastructure with technological installations should also be constructed in accordance with the design doc. and an information board with minimum dimensions of 80 x 120 cm containing: beneficiary's name, title of the project, project objective and logotypes.
