Desalination is common solution to a fresh water scarcity. The common desalination units are made of metal, which bring some disadvantage as corrosion or heavy weight. The presented paper discribe principle of polymeric distillation and present results of experimental verification of prototype of fully polymeric distillation. This prototype is based on air gap membrane distillation and combines two type of polymeric hollow fibers. Porous hollow fibers were used as membrane and the non-porous hollow fibers were used for the condenser. The prototype was operated in long-term continuous operation. Six experiments with different flow rate and temperature were done. During testing the temperature, humidity and amount of condensate was measured.

Desalinace je běžným řešením nedostatku vody. Běžné desalinační jednotky jsou vyrobeny z kovu, což sebou nese nevýhody jako koroze nebo velkou hmotnost. Tento článek popisuje princip polymerní destilační jednotky a prezentuje výsledky experimentálního ověření prototypu plně polymerní destilace. Tento prototyp je založen na air gap membránové destilaci a kombinuje dva druhy polymerního dutého vlákna. Porézní duté vlákno bylo použito jako membrána a neporézní duté vlákno jako kondenzátor. Prototyp byl v dlouhodobém provozu. Bylo provedeno šest experimentů s různým průtokem a teplotou. Během testování byla měřena teplota, vlhkost a množství kondenzátu.
