In connection with the construction of the new hospital in Drammen, Nordisk Vannteknikk has delivered an advanced treatment plant for the treatment of water from the construction process. The project represents a step forward in implementing sustainable practices in the construction industry, while taking into account the protection of the surrounding environment.
In collaboration with local authorities and construction contractors, we have put together a tailor-made solution to handle the large volume of water generated during the construction process. Rainwater, groundwater and surface runoff are collected and channeled through the facility. This system uses modern purification technology to remove particles, sediments and any contaminants from the water.
The purified water is carefully monitored to ensure it meets strict quality standards before being released into the fjord. This not only helps protect the fjord environment, but also shows the way for other construction projects that seek to minimize their impact on nature.
New Drammen Hospital
The plant is a complex mobile system consisting of a number of components for optimal performance. A combination of different treatment methods is used, including traditional sedimentation together with chemical precipitation, to achieve the best possible results while reducing the footprint of the plant.
A lamella separator solution is also used due to high water flow in certain periods. The lamella separator is a sedimentation tank with built-in lamellas and a screw in the bottom for continuous sludge removal.
The smooth surfaces of the slats ensure that sediments sink to the bottom faster, which leads to faster sedimentation time and therefore higher water flow in the same footprint. The sludge auger continuously removes sludge from the tank so that shutdowns for emptying are not necessary and downtime is thus significantly reduced.
The project in Drammen is a living example of Nordisk Vannteknikk's expertise in advanced water treatment and their commitment to finding innovative solutions to complex environmental challenges. Through this project, they have not only contributed to a cleaner fjord, but have also set a new standard for responsible water management in the construction industry.
