Abstract
Sve veći porast gradskog stanovništva, razvoj industrije i energetike, povećanje komunalnog otpada i razvoj masovnog turizma dovode do emisije štetnih metala u okoliš. Navedeni antropogeni izvori znatno onečišćuju vode u prirodi teškim metalima, stoga je neophodno razviti metode uklanjanja teških metala iz vode na siguran i ekološki prihvatljiv način. U ovom radu ispitana je učinkovitost uklanjanja teškog metala olova iz otpadne vode sorpcijom na nusproizvodima/otpadu iz prehrambene industrije (košticama maslina, peletu od komine maslina, ostacima hridinskog ježinca, košticama trešanja i košticama višanja). Sorpcija olova provedena je šaržnim postupkom iz otpadne vode koncentracije 0,5 mmol Pb/L i 1,5 mmol Pb/L. Svi ispitani biosorbensi pokazali su potencijal uklanjanja olova iz obiju otpadnih voda. Bolje uklanjanje olova postignuto je pri nižoj početnoj koncentraciji. Najveću učinkovitost pokazale su koštice višanja i to 83,65 % pri nižoj početnoj koncentraciji olova te 54,90 % pri višoj početnoj koncentraciji. Iako je postignuto prilično dobro uklanjanje olova iz otpadne vode, zaostala koncentracija olova bila je iznad zakonom propisanih vrijednosti za ispust efluenta u površinske vode i u sustav javne odvodnje. Stoga bi buduća istraživanja trebalo usmjeriti na modifikaciju ispitanih biosorbenasa radi povećanja njihove učinkovitosti u obradi voda onečišćenih olovom.
Abstract (english)
Increase in the city's population, the development of industry and energetics, the increase in municipal waste and the development of mass tourism lead to the emission of harmful metals into the environment. The mentioned anthropogenic sources significantly pollute water in nature with heavy metals, thus it is necessary to develop methods of removing heavy metals from water in a safe and environmentally friendly manner. In this diploma thesis the effectiveness of lead removal from wastewater by sorption using by-products/waste from the food industry (olive pits, olive pomace pellets, residues of the sea urchin, cherry pits and sour cherry pits) was examined. Sorption of lead was carried out by a batch performance from wastewater containing 0.5 mmol Pb/L and 1.5 mmol Pb/L. All tested biosorbents showed the potential for lead removal from both wastewaters. Better removal was achieved at lower initial lead concentration. The highest efficiency of 83.65 % was obtained by sour cherry pits for lower initial lead concentration and 54.90 % for higher initial lead concentration. Although a good lead removal was achieved, the residual lead concentration was still above the prescribed value for discharge into the public sewage system and into the surface waters. Therefore, future research should be focused on the modification of the tested biosorbents in order to increase their efficiency in treatment of lead polluted water.
