Abstract

PURPOSE: To plan the separation of scale components together with turbidity components, by separating with the permeable membrane, after the pH value of the separated liquid obtained by adding the precipitate-forming agent for removing the hardness ions to the seawater, has been regulated to the range at which alkaline scale does not deposit.
