Water treatment system

Can you please help me to set up the water treatment system because my water is very bad condition :
Total aerobic plate count at 37 c - 24h : 890 CFU/ml
Total aerobic plate count at 22 c -72h : uncountable/ml
Total coliforms : < 1 CFU/100ml
Thermotolerent Coliforms : < 1 CFU / 1ooml
Escherichia coli : < 1 CFU / 1ooml
Enterococcus Faecalis : < 1 CFU / 100ml
Sulfite reducing anaerobes : < 1CFU /100ml

So as this results i really don't know how can i set up the water filter.
I would like you to help me to find out the solution.
