Abstract:Magistrsko delo prikazuje študijo iskanja rešitve čiščenja osnesnaževal iz matične lužnice, ki nastane pri proizvodnji psevdoboemita, s pomočjo različnih separcijskih metod, s katerimi bi proizvedena odpadna voda ustrezala standardom za odvajanje odpadne vode v javno kanalizacijo ali ponovno uporabo v proizvodnem procesu. Predstavljeno je po katerih karateristikah se psevdoboemit razlikuje od preostalih aluminijvih spojin. Opisana je proizvodnja psevdoboemita v podjetju Silkem. Uporabljene so bile različne separacijske metode: filtracija, kristalizacija s pomočjo ohlajanja, reverzna osmoza, nasičenje raztopine z Al2(SO4)3, Ca(OH)2, NaAlO2, Na2(SO)4 ter uvajanje CO2. Metoda s katero bi dosegli željene rezultate mora biti primerna za uporabo v industiji ter biti ekonomsko spremljiva. Rezultati preizkusov kažejo, da je možno s pomočjo reverzne osmoze in podhlajevanjem matične lužnice doseči potrebne mejne vrednosti za ponovno uporabo odpadne vode v tehnoloških procesih.

Title:Use of separation processes in mother liquor treatment from pseudoboehmite production process
Abstract:In this master thesis, a study is presented to find a solution for the treatment of pollutants from the mother liquor generated during the production of pseudoboehmite, using different separation methods, so that the resulting effluent meets the standards for discharge into the public sewer system or reuse in the production process. The properties that distinguish pseudoboehmite from other aluminum compounds are presented. The production of pseudoboehmite in the company Silkem is described. Various separation methods were used: Filtration, crystallization by cooling, reverse osmosis, saturation of the solution with Al2(SO4)3, Ca(OH)2, NaAlO2, Na2(SO)4 and introduction of CO2. The method used to obtain the desired results must be suitable for industrial use and economically viable. The results of the tests show that it is possible to achieve the established limits for the reuse of waste water in technological processes using reverse osmosis and cooling of the mother liquor
Keywords:pseudoboemite, wastewater, neutralization, cooling, filtration
