The Mixing System of Saturated Salt Solution and Seawater Salt Purification Process Using Hydroextraction Method

The hydro-extraction process is one of the ways to purify and improve the quality of salt. Until now, the development of salt purification technology using the hydroextraction method has not been carried out where one of the processes of the hydro-extraction method is the mixing process. The design of the mixing system for the salt purification process starts from the design of hardware and software designs. In addition, an automation system design is also carried out to automatically control the actuators by using the solenoid valves and DC motors. The measurement system uses an ultrasonic sensor HC-SR04 which has functions to measure the volume in the salt solution tank with an average measurement correction of 0.5, an average error of 0.17%, and an accuracy value of 95.3%. Measurement of volume in the salt tank with an average measurement correction of 0.05, an average error of 0.039%, and an accuracy value of 94.5%, as well as a level measurement in a mixing tank with an average measurement correction of 0.5, an average error 0.06%, and an accuracy value of 95%. Sensor monitoring data will be displayed on an LCD display and can be accessed on a smartphone via the Blynk application.
