As an energy saving and environment protecting wastewater treatment method
freezing concentration is a new way not only to solve the problems of water pollution but save energy and ease the water demand in water scarce areas.Compared with evaporating wastewater treatment
freezing concentration has a huge energy-saving potential.Through theoretical analysis and calculation under the design conditions
it is obvious that the freezing concentration method use 30.35% less energy than evaporating in wastewater treatment.It consumes about 45.7% less energy while using pre-cooling method in freezing concentration.Moreover
it consumes about 62.5% less energy while combining freezing concentration with pre-cooling method and ice thermal storage technology.
