Chalk is calcium carbonate, which is insoluble in water. Hence, it can easily be removed by filteration. Moreover, calcium carbonate has reverse solubility in water, i.e. its solubility reduces with increase in temperature. Thus, the solution may be heated and then filtered.

Chalk particles can be collected by using a filtration process. A filter paper or a fine sieve can be used to separate the dissolved chalk particles from the water. The water can then be evaporated to obtain the solid chalk residue.

Why do you need water softening?
there is chalk (CaCo3) in the water, which makes the water "hard"... i.e. if you wash your clothes, the fabric becomes stiff. But adding an agent to the chalky water will "soften" it, this means that the chalk will chemically be removed.
