Abstract
PURPOSE: To enhance the thermal efficiency of a drainage treating process by heating the drain water by utilizing the waste heat produced upon heating and drying of concentrated drain water produced in a desalting treatment and by treating the drain water by means of a reverse osmosis or electrodialysis after the reduction of liquid resistance of the drain water by heating a stock water introduced into a desalting device without a particular heat source.
