Retriving distinct values from column cell

Hi Guru's,

In my table - in a particular column the records are stored in this way, for ex:

Dept_ID
--------
10,20,10,30,20,30,40,10,40

I need to get the distinct value for this column, the output I need is,

Dept_ID
--------
10,20,30,40

Thanks in advance,
Stration
