PRODUCING METHOD OF BOILED DOWN SALT USING FINAL EFFLUENT FROM A SEAWATER DESALINATION PLANT

摘要

PURPOSE: A producing method of boiled down salt using final effluent from a seawater desalination plant is provided to use brine obtained from the seawater desalination plant to obtain the salt with all the minerals from sea water.;CONSTITUTION: A producing method of boiled down salt using final effluent from a seawater desalination plant comprises the following steps: burying a pipe(120) with plural through-holes(110) on the surface in clean foreshore(200) for the predetermined time; installing a filter layer(300) in between the pipe and the foreshore for collecting brine passed through the filter layer and mud on the surface of the foreshore in a brine tank(100); discharging the brine from the brine tank unit a pump(400); rapidly cooling the brine, and separating ice from the brine; and heating the brine at 60-200 deg. C for 24-72 hours until the salinity of the brine is 22-30%.;COPYRIGHT KIPO 2013
