hiervoor heb je verschillende manieren. je kan door middel van stofeigenschappen de beste
scheidingsmethode uitkiezen.

bezinken: dichtheid bij suspensie (vaste stof+vloeistof, troebel) en emulsie
(vloeistof+vloeistof, troebel). het component met een grotere dichtheid
zakt naar beneden.
centrifugeren: versneld bezinken door ronddraaiende
beweging.

filtreren: deeltjesgrootte bij suspensie. het mengsel
passeert een filter. de
vloeistof kan door het filter heen en heet

achterblijft heet het residu.
