I have always liked pulling vac on a vac flask and pulling the solution through https://www.amazon.com/dp/B07LCKBKCT/ref=cm_sw_r_cp_apa_i_Z5fgFb2VB8BWF those water filters. I would stage them 100-25-1 micron or something like that. Ghetto and probably not the best but it works for under $500 everythang including a pump
