The device for treatment of technological wastewater, of capacity 50 m3/day was delivered in 2020. Technological wastewater is generated during washing truck tanks.
Inlet wastewater parameters did not meet the values for water discharge into the Vrbas River.
Based on the input parameters, DAF technology with a combination of biological treatment, SBR (Sequencing Batch Reactor) was selected for the treatment of technological wastewater.
The capacity of DAF is 5 m3/h, while the capacity of SBR is 150 PE.
Produced sludge is gravitationally dehydrated by filter bags (Figure 2) after treatment, and is previously prepared by polymer dosing and mixing in a static mixer (Figure 1).
