Eksperimentalno testiranje postopkov nanofiltracije poliamidamin-epiklorohidrinskih smol : magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo

Zwitter, Matej

V nalogi obravnavamo diafiltracijo raztopine PAE smole z namenom zmanjšanja vsebnosti stranskih produktov DCP in MCPD. Uporabljeni sta nanofiltracijski membrani Koch SR3D in Koch SelRO MPS-34, obe s ... parametrom MWCO 200 daltonov. Spremljamo kratkoročno in dolgoročno spreminjanje permeabilnosti membran in stopnjo zadrževanja DCP in MCPD. Filtracija je izvajana pri nevtralnem pH. Rezultati kažejo, da skladno s pričakovanji PAE smola membran ne prehaja. V nasprotju s pričakovanji DCP in MCPD skozi membrano ne prehajata neovirano. Rezultati kažejo tudi, da se membrana tekom delovanja ne maši, maši pa se med mirovanjem naprave. Sprememba pH med čiščenjem tako v kislo, kot v bazično okolje prispeva k hitrejšemu mašenju membrane. Diskusija obravnava mehanizme zadrževanja DCP in MCPD ter mašenja membran.
