Preventing Obstruction of Water Intake from Frazil Ice

Frazil buil-up can obstruate water intakes

Frequent obstruction of a water intake by frazil (newly formed or slushy ice) buildup in winter has the potential to interfere with the pumping of water for nuclear power plant cooling systems, for municipal water supplies and even for fire control authorities.

By definition, frazil is a thin layer of ice that forms on the surface of the water. Frazil can build up on the intake grates and clog them. In the presence of a risk of active frazil formation, two deicing technologies have been used in combination:

The customer is very satisfied with the results of combining these two deicing systems.
