26180 Voluntary ex ante transparency notice module based, container based cleaning system.

The need and framework conditions at the plant. The municipality ́s existing sewage treatment plant has shown inadequate treatment ability connected to BOF5 and KOF. The system has sufficient hydraulic capacity, but lacks the necessary purification effect to fulfil the requirements for secondary purification. The treatment plant serves approx. 6,500 pe and handled approx. 450,000- 500,000 m³ sewage in 2025. The municipality therefore needs a system that can quickly increase the purification effect, at the same time that the existing installations can be continued and optimised in a transition period. The municipality ́s need is functionally and operationally justified. The system must be able to handle varying amounts of water and loads, have high hydraulic capacity, low area need and preferably be established without a new permanent building or comprehensive reconstruction of the existing treatment plant. Furthermore, it is necessary that the system is movable, scaleable and module based, so that the municipality can adapt the placement and capacity if the operational conditions or need change. The system must also have self-cleaning mechanical filtration, integrated management, continual process monitoring and data collection. This is necessary in order to ensure stable cleaning effect and to give the municipality a better actual basis for further operation and any new future cleaning requirements. It is of significant importance that the solution can be established …
