Remember all I want is pour water which I can get by the distillation, but the problem is that the methanoic acid will also the distill over because it has the same boiling points as water. To work around this, I first neutralize the acid with sodium hydroxide. The mixture now is that of salt, water and sand. Since I only need pour water, I get it now through distillation

No neutralization is not part of seperation techniques

the first process would be FILTRATION in order to remove the sand, then DISTILLATION is used to separate the liduid.
