  • Development phosphate removal from RO brine

    During Reversed Osmosis (RO) in water purification not only pure water but also a high salt fraction (brine) is generated. In order to prepare this brine for discharge to a sewer system or WWTP Colsen develops a pellet reactor in close collaboration with PEKA Kroef (Odiliapeel, NL). Via co-crystallization of salts on an inorganic “germ” pellets are generated with a diameter of 2 to 8 ...

  • Long-term seawater analysis has global significance

    Since 1988, scientists from the University of Hawaii have been conducting almost monthly deep-sea research expeditions to collect water samples for subsequent laboratory analysis. Originally designed to characterize subtle long-term changes in environments that were believed to be stable, the work has revealed some surprising conclusions. For example, it has become evident that even in these ...

  • Soil – the living skin of planet earth

    The soil forms the outer skin of the land masses of Planet Earth. This thin veneer of living material is sometimes only a few centimetres thick and rarely thicker than two or three metres, but it has critical influence on what happens on the surface of the Earth. Soil is our life-support system. It provides anchorage for roots; holds water long enough for plants to make use of it; and holds ...
