Primerjava ročnega in avtomatskega sistema spremljanja membran za reverzno osmozo
Ibrahim Mujezinović, 2023, undergraduate thesis

Abstract: Ta diplomska naloga raziskuje prehod iz ročnega na avtomatsko spremljanja membran reverzne osmoze. V nalogi je opisan koncept reverzne osmoze in podobnih filtracijskih tehnologij, kot tudi pomembnost spremljanja stanja membran med postopkom filtracije. Prav tako je predstavljena vloga senzorjev pri avtomatskem spremljanju delovanja membran. V nalogi so opisane različne metode za spremljanje stanja membran, s poudarkom na senzorjih. Razloženo je, kako senzorji delujejo in kako zbirajo relevantne podatke o delovanju membran. Prav tako je opisan način, kako omogočajo avtomatsko spremljanje. Predstavljena je tudi primerjava med ročnim in avtomatskim spremljanjem membran reverzne osmoze. Razložene so prednosti avtomatskega spremljanja, kot so hitrejše odkrivanje težav, zmanjšanje človeških napak in izboljšanje celotne učinkovitosti postopka filtracije. Na koncu naloge je izvedena analiza, ki preučuje uporabo membran reverzne osmoze s senzorji in brez njih.

Primerjava ročnega in avtomatskega spremljanja podatkov proizvodnega procesa na primeru proizvodne linije alternatorjev : diplomsko delo
Nejra Ajanović, 2021, undergraduate thesis

Abstract: V diplomskem delu se ukvarjamo s preverjanjem kakovosti delovanja proizvodnje in kakovosti izdelkov na proizvodni liniji montaže alternatorjev. Opisujemo dele izdelka in kako poteka njegova sestava. Pri tem določimo, katere meritve in parametre moramo zagotoviti pri izdelavi kakovostnega izdelka za boljše razumevanje obravnavane vsebine. Ugotavljamo, ali avtomatsko spremljanje podatkov (statistični nadzor procesa) že zamenjuje ročno spremljanje podatkov ter človeški del, ki je v vsakem proizvodnem procesu neizogiben. Avtomatski način je opisan s SPC metodologijo in njenim delovanjem v ozadju orodja Q-DAS. Ročni način preverjanja podatkov je opisan z izvajanjem večnivojskih presoj procesa. Na proizvodni liniji montaže sta obe metodi aktualni in se trenutno izvajata hkrati, vendar se rezultati uporabljajo za različne namene in se rezultati med seboj dopolnjujejo. Ugotavljamo, koliko so podatki kakovostni, sledljivi in uporabni, glede na način zbiranja podatkov. Zaključek smo naredili na podlagi teoretičnega in praktičnega primerjanja metod, končnih poročil in statistik.

Zasnova sistema za ciljno spremljanje porabe energije
Janko Kavčič, 2016, undergraduate thesis

Abstract: Metoda ciljnega spremljanja porabe energije je učinkovito orodje, s katerim lahko nadzorujemo porabo energije v podjetju. Opira se na meritve ter na pravilno odločanje in ukrepanje. V diplomskem delu obravnavamo problem ustvarjanja prikazov, vizualizacij in poročil iz neobdelanih podatkov, ki jih posredujejo merilniki porabe v bazo podatkov. Iz teh ustvarjenih prikazov lahko nato različne skupine zainteresiranih uporabnikov hitro vidijo informacije, ki jih zanimajo. Prikazi vsebujejo linijske grafe in tabelarične prikaze o porabi energije strojev, korelacijske diagrame o porabi energije glede na proizvedeno število izdelkov, glede na proizvedeno maso izdelkov, glede na število udarcev stroja ter graf kumulativne vsote in treemap prikaz. Ti prikazi služijo energetikom za lažje analiziranje stanja in odločanje o nadaljnjih ukrepih ter kot poročila nadrejenim. V diplomskem delu smo ugotovili, da je konstantno spremljanje izredno pomembno za obvladovanje energetskih tokov. Prikazi omogočajo lažje in hitrejše primerjanje porabe energije proizvodnih strojev med sabo in tudi z drugimi proizvodnimi spremenljivkami, hitreje se odkrivajo napake in se zato tudi hitreje odpravljajo. Tudi odločanje o nadaljnjih ukrepih je lažje, saj je na voljo več podatkov, prav tako je učinkovitejše spremljanje učinkov teh ukrepov in nadaljnje načrtovanje proizvodnje.

THE EFFECTS OF MIXED COMMUNAL WASTE RECYCLING MANAGEMENT IN SLOVENIA - CASE STUDY
Peter Bohinec, 2016, master's thesis

Abstract: With the adjustment of the Slovenian legislation with the European one we have an obligation to increase the reuse and recycling target for municipal solid waste by up to 65% by 2030 and gradual limitation of the landfilling of municipal solid waste to 10% by 2030 (Directive 2008/98 on waste, 2015). This represents a major challenge for municipalities in Slovenia. This study contains a plan for establishing new waste treatment facility in the Municipality of XY. As all new constructions in Slovenia, the presented facility needs to provide all the environmental protective measures predicted by the legislation. Beside the legislation, it is also important to ensure that new waste treatment facilities will have a low or no effect on the environment. Based on the Environmental Protection Act and the Construction Act of Slovenia, measures to ensure long term monitoring of the waste treatment facility as a case study in the Municipality of XY are presented. Before constructing the new facility, the track of “baseline” – a one-year monitoring of the following environmental parameters was crucial: groundwater, air dust deposit, condition of the soil on the area where new facility will operate in the future. The thesis points out the importance of the so-called track “baseline” monitoring of environmental parameters before new waste treatment facility will operate. This will be the basis for the introduction of operating monitoring for the new waste treatment facility in the future. Data for the analysis of presence of pollutants were acquired from groundwater, air dust deposit, soil sampling and containment of chemical pollutants. The following methods of analysis were employed in the acquisition of laboratory results of specific physical and chemical parameters: ion chromatography, gas chromatography, spectrophotometry, titration, inductive coupled plasma – mass detector, measurement with an electrode. It was determined that in the period between 2011 and 2012, the groundwater samples taken from three drilled wells containing pollutants as for example in the P-2 well there were adsorbable organic halogens - AOX, boron and mineral oils found. The results of the dust deposit show increased value of lead and zinc. More concerning are analysis of the soil samples where the quantity of copper at the MM2 measuring point were 530mg/kg, on 20 April 2012 the present critical level was 300 mg/kg. At the same measuring point (MM2) on the same day, the value of zinc was 650 mg/kg and almost reached the critical level of 720 mg/kg. The levels of heavy metals as cadmium, copper, lead and zinc in the soil samples taken at the MM2 and MM3 measuring points were at the warning level. All the detected parameters were evaluated and present a good basis for future operational monitoring of the environment in the area of the new waste treatment facility in the future. This case study has shown that planned steps in the improvement of the waste management in the Municipality of XY are crucial to protect the environment. The analysis and interpretation present an important basis for planning and monitoring a new waste treatment facility which will help to improve our goals and reduce landfilling to 10% and increace recycling by up to 65% by 2030 as predicted by the Directive on waste (Directive 2008/98 on waste, 2015).
