Contract specification 6. Contract description: Construction of works of Trencin right bank wastewater treatment comprising: - lot 1: Kostolná-Zárecie and Brnianska sewer system; - lot 2: storm overflow, pumping station and delivery mains; - lot 3: wastewaster treatment plant. Lot 1: Kostolná-Zárecie and Brnianska street sewer system The Brnianska street sewer would collect urban wastwater forming a mixture of domestic sewage and industrial wastewater. The sewer system is combined. The sewer system proposed to serve the village of Kostolná-Zárecie is based on separate system. No important producers of industrial wastewater are present. The settlement does not have a comprehensive sewer network and a WWTP so far. The only existing installations are street drainage to carry off storm water flows. Generally, private cesspools and septic tanks are used to dispose of the sewage produced in the village. No - Kostolná-Zárecie - Capacity - Solution: 1 - Pressure piping V5 - DN 80 / 144 m - Pumping station 3 and piping; 2 - Pressure piping V4 - DN 100 / 132 m - Pumping station 2 and piping; 3 - Pressure piping V3 / WWTP connection - DN 100 / 731 m - Pumping station 1 and piping; 4 - Sewer system of Kostolná-Zárecie - DN 300 / 2 310 m - New PVC. Brnianská street sewer The catchment area of Brnianská street does not have a comprehensive sewer network so far. The only existing installations are street drainage to carry off storm water flows. Technical solution: DN 400, 290 m; DN 500, 341 m; Summary, 631 m of sewers. Lot 2 and lot 3: Pumping station and WWTP The pumping station and WWTP works scope of 30 150 PE60 is summarized below: wastewater will be carried via a combined sewer to the inlet pumping station. The inlet is equipped with a gravel trap and automatic screens to ensure mechanical pre-treatment. The wastewater is pumped to the WWTP via two pressure lines. At the WWTP, the liquid then flows through all purification stages by gravity. The WWTP inlet flow is measured by electromagnetic meters. The total hydraulic load entering the system is carried further on to the mechanical treatment system. At the mechanical treatment plant, two lines of very fine screens with automatically operated rakes and aerated grit and grease chamber are installed. The biological stage of the treatment plant a two-train activated sludge process system based on a deep oxidation ditch (similar to carousel) design. The contents of tanks should be homogenized using submersible mixers (flow-boosters). The aerobic sections should be equipped and aerated with a fine-bubble diffuser system. The activated sludge mixed liquor will leave the aerobic-zones of the activated sludge process tanks to fill two circular (deep) secondary setting tanks. The WWTP effluent flow is monitored by a Parshall flow-meter. The biological stage includes a blower plant. The plant is equipped with rotary blowers, driven by electric motors with speed control to regulate the supplied air rate. The settled activated sludge will be drawn into the return activated sludge pumping station to be distributed by return sludge pumps into the two available activated sludge process trains. The excess activated sludge will be drawn off discontinuously from the sludge pumping station and fed into the sludge treatment plant. The sludge treatment stage shall comprise mechanical devices for excess sludge thickening and a centrifuge for sludge dewatering. Two aerated sludge holding tanks will be provided (for use according to seasonal operation needs) to stabilize the thickened sludge. The sludge liquor is collected in a sump and then dosed to the activated sludge process. To ensure the sludge stabilization (according to seasonal operation needs) a lime station will be installed as well. A system based on PLC has been suggested to support the automated operation of the WWTP. The plant should be subordinated to the existing water-management dispatching centre in the operators headquarters in Trencin-left bank. Total operation staff of the Trencin right bank WWTP shall number 4 persons. The supplied automation of pumping station and WWTP must consider this requirement. 7.
