Uporaba membranskih procesnih sistemov za pripravo pitne vode na podlagi razsoljevanja morske vode je na globalnem trgu v intenzivnem razvoju. Membranske tehnologije se hitro razvijajo, a so omejene na delovanje pri visokih tlakih. Razsoljevanje z reverzno osmozo poteka zaradi vzpostavitve tlaka v sistemu, ki je večji od osmotskega tlaka. V delu sm...

Reverse Osmosis method is efficiently and widely used in drinking water production. Treatment of ground water faces three` main problems: scaling of membranes, concentrate handling and permeate ionic composition. A number of ionic pollutants (such as lithium, ammonia and boron) are poorly rejected by reverse osmosis membranes as compared to calcium...

Recent studies have increasingly applied machine learning (ML) to aid in performance and material design associated with membrane separation. However, whether the knowledge attained by ML with a limited number of available data is enough to capture and validate the fundamental principles of membrane science remains elusive. Herein, we applied expla...
Postopki razsoljevanja za pripravo pitne vode so zaradi vse večjega globalnega pomanjkanja kakovostne vode čedalje bolj pomembni. V magistrski nalogi obravnavamo komercialni sistem za pripravo pitne vode z RO iz virov z visoko vsebnostjo ionov, predstavljeni pa so tudi glavni elementi. V eksperimentalnem delu smo ugotovili, da se z večanjem vsebnos...

Manganese is the Earth's crust's third most abundant transition metal. Decades of increased mining activities worldwide have inevitably led to the release of large amounts of this metal into the environment, specifically in water resources. Up to a certain level, manganese acts as an essential micronutrient to maintain health and support the growth...
