Abstract

PURPOSE: To obtain the maximum desalinating power, while reducing the generation amount of waste matter, by obtaining a desalinating rate from a flow rate and electric conductivity at an inlet and an outlet, and reducing a flow rate in the filtering desalinator where its desalinating rate is below a preset value and a pressure difference between the inlet and the outlet is above a preset value.
CONSTITUTION: Signals from an electric conductivity meter 10, a differential pressure gauge 11, a flow meter 9, etc. are inputted into a controller 13, and a result calculated by the circuit is fed to a flow rate-control valve 5 to adjust a feeding flow rate. In the controller 13, the sum of the products of the difference of electric conductivity between an inlet and an outlet with flow rates is obtained by operators 21, 22, and a value "1" is outputted to a part 30 by an operator 23 when the sum is smaller than a preset value Rμ. A value "1" is outputted to a part 29 by an operator 20 when a pressure difference is larger than a preset value Rp, while a value "1" is outputted to a part 31 by an operator 24 when the flow rate is larger than a preset value RF. The logical product of signals from parts 29, 30, 31 is obtained by an operator 25. Its result is integrated by an operator 26 and utilized as a signal 14 for the opening rate of a flow rate- control valve.
