Investigation of Deposit on Heat Exchange Tubes in Desalination Plants and Its Removal by Sponge Ball Cleaning

Abstract

he author studied application of the sponge ball cleaning method to scale prevention for heat exchange tube surfaces in the flash evaporators by using the fundamental test apparatus.
As the results of tests, they clarified followings:
(1) In applying any scale prevention method, removal of sludge on heat exchange tube surfaces is indispensable
(2) The sponge ball cleaning method could become one of effective scale prevention methods for the flash evaporators.
(3) A, surface of heat exchange tubes is not given any damage by the sponge ball cleaning.
