I want to build a DIY vacuum filtration apparatus with a bike pump but it's very difficult to find one the could be easily converted into a vacuum pump. This prompted an idea to simply build a reverse version where above atmospheric pressure is forcing the liquid to flow through the filter. I notice pressure filtration is rarely mentioned in write-ups, unlike vacuum filtration. Is there a reason for this inpopularitylack of popularity or a reason why such a DIY apparatus would likely not work?

edit: couldCould it be that vacuum is necessary for drying the paste that forms at first because it enhances evaporation?

Why isn't pressure filtration popular compared to vacuum filtration?
