Tender Details

Expansion of the Horsens Central Wastewater Treatment Plant The Horsens Central Wastewater Treatment Plant is designed for 210, 000 PE with a high degree of industrial load, and is sometimes heavily loaded if you start from traditional static dimensioning calculations and now being plant configuration. Nevertheless, the treatment plant has performed well in relation to a previous nitrogen requirement of 8 mgTN/l. The treatment plant has now, as part of the Implementation Order, been imposed a stricter treatment requirement of 3.5 mgTN/l at the end of the treatment plant. Overall, this means that the biological capacity must be expanded so that the treatment plant can comply with an average discharge requirement of 3.5 mgTN/l. Due to the increased hydraulic load resulting from increasingly extreme rainfall events, Horsens Centralrenseanlage's hydraulics have been updated in recent years. It included new grates, new inlet pumps, updated intermediate pump station and a heavy slurry plant (S::Select). Now the turn has come to sand and grease capture, where the treatment plant is process-technical limited to 2, 700 m3/h, while hydraulically it is limited to 6, 500 m3/h. It is desired to double this capacity, so that at the end of the project at the treatment plant there will be two new/renovated sand and grease traps with a total process technical capacity of 5, 400m3/h and a hydraulic capacity of 13, 000m3/h. The project is offered as a turnkey contract, including project design, soil and concrete work, blacksmith and machine work, electrical work, groundwater lowering and cleaning, etc.
