Abstract

The aim of the study is to investigate the effect of initial salinity and water flow rate on desalination processes in icicles formed on horizontal nozzles.

Experimental installation, is a frame on which are fixed: a container with initial salt water, impact surface, horizontal nozzles. Initial saline water of 10-30 g/l flowed out through the hole, fell and crushed against the impact surface, and then froze on the nozzles in the form of icicles. To investigate the degree of salinity, the icicles were divided into equal parts and melted.

The results of the investigation show that the obtained water contains the most salts in those parts that are closer to the bases of the borules. At a flow rate of 2 ml/sec, the borules grew to their full length. The level of the option was defined as the ratio of initial water solubility to the received solubility and was 1.5 to 4, higher values were obtained at the flow rate of 1 ml/sec, and at the first intervals.

Conclusions: The results of experiments showed that it is impossible to refine brackish water in 1 cycle. To obtain drinking water with salt concentration less than 0.5 g/l it is necessary to use several cycles of freezing-melting or to combine with other methods of desalination. It is necessary to control the optimum water consumption to ensure a higher degree of (solidification)desalination.
