Sea water systems
Through-flowing filtered sea water is one of our most important facilities. We have deep water, with relatively high and stable salinity, and surface water, in which both salinity and temperature varies. Thanks to water reservoir and alarm to caretaker, the sea water systems are quite reliable.
For both deep and surface water entering the Kristineberg Main Building, salinity and temperature are continuously measured. It can be seen on the Water and weather data web page. Compiled measurement results from 2007-2013 and 2016-2018 are shown in diagrams below.
The deep water intake is at 32 metre depth. It is pumped up through the Main Building to a water reservoir on the third floor. The water is flowing through four serie-connected tanks, where sediment and large particles sinks. From the last tank, the water flows down through the building to the laboratories. In the thermoregulated rooms there are screen filters in the taps. In other labs, water is unfiltered.
The surface water intake is at 7 metres depth. This water is usually available in the laboratory from April to November. The water is pumped to the water reservoir on third floor of the Main Building. From here it flows through tanks and down into the laboratories.
