Ion Migration Patterns and Mechanisms of Melting Brackish Water Ice by Gravity-Induced Desalination

Published: Jan. 1, 2024

The melting process of brackish water ice has more desalination effect than the formation ice. In this experiment, crystals produced by single-stage progressive freezing under different conditions icing temperature and raw ion concentration were utilized to carry out gravity-induced (GD) conventional tests. migration pattern Cl-, SO42-, CO32-+HCO3-, Na+, K+, Ca2+ Mg2+ crystal masses was explored. results showed that removal rate tended decrease with continuation GD average concentration. When decreased, a decreasing trend. ice-melt during an exponential decay, type changed from Na·Mg-Cl Na-Cl·SO4. There differences in rates each melt. Among them, discharge distribution Cl- > Na+ SO42- Ca2+, Mg2+, CO32-+HCO3- K+. SO42-. key factors affecting are relative mass, polarizability, radius, temperature, And significantly positively correlated other influencing except mass. model can be used accurately predict mixed process. Using as target for user demand improve production rates. Compared using instantaneous collection point, improved 27.40%. application prediction is presented way case study.

This research aims to analyze the effect of temperature differences on electric voltage and determine Seebeck coefficient in making a tool, namely Thermoelectric Generator. The experimental variables used this experiment were Peltier dynamo-type control variables, ice manipulation cold side, propeller speed response variables. type is TEG-SP1848-27145 SA 5V dynamo. was carried out by connecting peltier dynamo placing objects both sides with different temperatures. fire originating from candles for hot part part. Based experiments that have been out, it can be concluded greater difference, voltage. lower propeller.
