WATER TREATMENT Process Pumps

Water flows (1) to the treatment plant from the reservoir or stream through rotating screens (2) to remove large debris. It is then pumped into the plant where alum is added (3) to cause coagulation. After rapid mixing, the water remains in the settling basin (4) while sedimentation of floc occurs (2-4 hours). The water treatment residual (settled floc) is pumped from the bottom of the pools and ...

Calculating ‘old’ and ‘new’ water runoff

Just ahead of a rainstorm, Cody Ross might run out to an agricultural research site as part of his graduate work. He’ll need to get some dye into an injection well. The point? To evaluate the path that water follows from the field during and after the rainstorm. Ross, a member of the Watershed Systems Research Program at the University of Manitoba, is measuring water flow in a part of the ...

Trawling threatens to destroy deep-sea ecosystems

Intensive trawling could turn seafloor ecosystems into ‘deserts of the sea’, new research warns. The study found that continuous bottom trawling for shrimp in a deep-sea Spanish canyon has damaged the foundations of marine ecosystems by dramatically reducing seafloor biodiversity and nutrients in sediment. Increasingly, fishers around the world are taking bottom trawling further, and ...

The bad oxygen conditions in the Baltic Sea continue

The serious oxygen conditions that have affected the Baltic Sea during the 2000s continue. The oxygen survey performed during autumn 2013 show that 15% of the bottom areas are dead due to total absence of oxygen and about 30% suffer from acute oxygen deficiency. Sad development SMHI have analyzed the oxygen situation in the Baltic Sea during the period 1960 to today. Up to 1999 the oxygen ...
