Aarhus Vand had planned to increase the capacity of Viby wastewater treatment plant in order to ensure stable and efficient treatment performance.
Due to the WWTP’s expected short lifetime (10–15 years), a cost-efficient capacity expansion should be achieved with minimum infrastructure interventions. The proposed solution is now implemented in full-scale operation at the WWTP with considerable improvements in operational stability.
In partnership with NIRAS, TechRas Miljø, EssDe and DHI we now have a solution relying on the optimisation of existing processes to achieve the desired increased capacity while minimising capital expenditures.
The result is:
The expansion of Viby WWTP during 2019-2020 has ensured improvements in effluent quality during peak loads and in the sludge quality. These outcomes have been achieved through a very constructive collaboration between the partners who provided the right solutions to achieve the desired end result.
