Is there any microfilter capable of filtering Aluminium, Strontium and Barium from drinking water?
Can any microfilters be used to purify aquifers water as well? How to purify extremely high values of above three from water?
Use caution with RO and Nano as these targets may precipitate and foul. Modeling will provide indications of precipitation and other recovery/rejection issues. Pretreatment will be critical.

Joseph is right. What are the levels of these elements in your raw water and what else do you have to eliminate?

Reverse Osmosis Membranes(RO) Modified with Ag2O Nanoparticles to Improve Performance for Nan particles filteration n orm of compound.
The process used m -phenylenediamine and trimesoyl chloride in hexane, incorporating silver oxide Ag2O nanoparticles of varied concentrations from 0.001 to 0.1 wt%. Ag2O nanoparticles were prepared at different sizes varying between 20 and 50 nm. The modified membranes characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), atomic force microscopy (AFM), transmission electron microscopy (TEM), and contact angle measurement.

NF membranes will reduce polyvalent ions. RO removes everything. Cation exchange will work for those ions. Also lime softening will remove Ba and Sr, probably not Al.

These metals are not present in pure metal but are present in compound form. So that's are not particles like you can filter it out.
These can be taken out either by chemical presentation or absorbing on media or Nano/RO membranes

No, not a Mirco filter.. For metal / contaminants at the atomic level like this you'll need reverse osmosis.
