Kuti mumvetsetse aluminium sulphate, ndikofunikira kumvetsetsa ntchito zake, kuphatikiza chithovu chamoto, kuyeretsa zimbudzi, kuyeretsa madzi ndi kupanga mapepala.Njira yopangira aluminium sulphate imaphatikizapo kuphatikiza sulfuric acid ndi zinthu zina, monga bauxite ndi cryolite.Kutengera ndi mafakitale, amatchedwa alum kapena pepala alum
Aluminiyamu sulphate ndi woyera kapena woyera kristalo kapena ufa.Sichigwedezeka kapena kuyaka.Ikaphatikizidwa ndi madzi, pH yake imakhala yochepa kwambiri, imatha kutentha khungu kapena kuwononga zitsulo, imasungunuka m'madzi, ndipo imatha kusunga mamolekyu amadzi.Madzi amchere akawonjezeredwa, amapanga aluminium hydroxide, Al (OH) 3, ngati mvula.Zitha kupezeka mwachilengedwe m'mapiri ophulika kapena kutayira zinyalala zamigodi.
