The subject of the procurement is the removal and disposal of waste water from the Waste Water Treatment Plant (WWTP).ž By conducting regular business processes of the Client, technological waste water is generated at the Biljane Donje WMC site, which is treated at the internal waste water treatment plant (WWTP). The UPOV purifies waste water through a combination of biological treatment and ultrafiltration. Biological treatment includes denitrification and nitrification processes in the MBR reactor. Wastewater collected in the receiving basin (leachate from non-hazardous waste landfills, drainage water from mechanical biological waste treatment plants - MBT plants, potentially contaminated surface water from traffic-manipulative surfaces) is pumped into the egalization basin, which serves to equalize the inflow to the next (biological) stage of waste water treatment. Biological treatment with a nominal capacity of 90 m3/day involves a process with active sludge in which the anaerobic and anoxic phases alternate, i.e. the processes of nitrification and denitrification. After the biological degree of treatment, water is referred to ultrafiltration where sludge and other suspended particles are separated from the water. Part of the sludge is recycled into the denitrification process, and the excess is discharged into a reinforced-concrete container. The disposal of excess sludge is not the subject of this tender. Permeate (purified water obtained by ultrafiltration) is temporarily stored in a buffer tank from where it is recycled if necessary, and the rest accumulates in a tank with a volume of 630 m3 where it awaits transportation for further treatment. The water treated at the WWTP Biljane Donje is treated to the level of quality of municipal waste water suitable for discharge into the public drainage system and is intended to be transported by tanker trucks to the treatment plant of the City of Zadar (in the event of unavailability of a waste water disposal site in the area of the City of Zadar, the Client will direct the contractor to alternative locations). The cost of waste water disposal is not the cost of the contractor , and the same supplier pays directly to the operator of the treatment plant to which the waste water is removed from the WMC site.
