The simplest method is the distillation of the solution.
If you have a pet that is drinking it ;o) Or if it is hot is it evapourating?
Most metallic chlorides are soluble in water.
Yes, most chlorides are water soluble
Generally chlorides are soluble in water. But not all the chlorides: for example the silver chloride, AgCl.
Reverse osmosis is an effective method for removing chlorides from water. It involves passing water through a semipermeable membrane that filters out impurities, including chlorides. This process helps to produce clean and purified water with reduced chloride levels.

Sodium and potassium chlorides are both soluble in water.
Sodium, potassium, calcium chlorides have the effect of lowering the freezing point of water.
Silver chloride and lead (II) chloride do not dissolve well in water.
After water evaporation minerals called evaporites remain as residues: chlorides, carbonates, phosphates, etc.
There are many soluble chlorides, such as sodium chloride (table salt), potassium chloride, calcium chloride, and magnesium chloride. These compounds dissolve readily in water to form clear solutions.
The most important are the chlorides of sodium, potassium, magnesium, calcium.
