Apstrakt
Stalni porast broja vozila na globalnom nivou negativno utiče na održivi razvoj zbog povećane potrošnje energije, buke i zagađenja vazduha, kao i povećane potrošnje vode koja se koristi za pranje vozila. Dominantni postprodajni servis u automobilskom sektoru je pranje automobila. Ako bi se otpadna voda iz autoperionica mogla ponovo koristiti u procesu pranja vozila, umesto sveže vode, mogla bi se značajno smanjiti potrošnja sveže vode. Kako bi se postigao ovaj cilj, neophodno je implementirati sisteme za prečišćavanje otpadnih voda „na mestu nastanka“ tj. u autoperionicama. U ovom istraživanju razvijeno je novo Pilot postrojenje za tretman, „na mestu nastanka“, otpadnih voda generisanih pranjem vozila u autoperionicama. Ovo pilot postrojenje predstavlja kombinaciju više metoda. Sastoji se od tri inovativna modula: višenamenskog reaktora (za koagulaciju/flotaciju, aeraciju/oksidaciju), filtera sa nasutim slojem (za filtraciju) i koalescera (za koalescentnu filtraciju). U svim ovim modulima materijali od kojih su formirani nasuti slojevi su izrazito laki (ekspandirani polistiren (EPS) i poliuretan (PU)), stoga je za njihovo pranje potrebna energija značajno niža nego kada je upitanju pesak koji se najčešće koristi kao filterski sloj. Pilot postrojenje ima jednostavnu konstrukciju i malu težinu, tako da se lako može premeštati po potrebi. Ovo novo razvijeno postrojenje pokazalo je veoma visoku efikasnost smanjenja HPK-a, kao i efikasnost uklanjanja suspendovanih materija i ulja, što ukazuje na njegov visok potencijal za rekuperaciji vode u autoperionicama.
