Analiza i izbor optimalne metode omekšavanja vode primenom vikor i ahp metode – studija slučaja

Abstract

Prečišćavanje sirove vode do nivoa neophodnog da bi se ona koristila za vodosnabdevanje naselja predstavlja veliki izazov, naročito imajući u vidu da sirova voda nikada nije opterećena samo jednim parametrom zagađenja. Napretkom tehnologija za prečišćavanje vode, posebno membranskih tehnologija, efikasnost tretmana postala je daleko veća. Postavlja se pitanje koja tehnologija je optimalna, u pogledu odstranjivanja štetnih materija, ekonomskih, ekoloških dobiti, itd. U izboru optimalne tehnologije tretmana vode značajnu pomoć mogu da pruže metode višekriterijmske optimizacije. U slučaju koji je razmatran u okviru ovog rada primenjene su metode VIKOR i AHP na izbor optimalne konfiguracije postrojenja za omekšavanje vode bazirane na nanofiltraciji. Metoda VIKOR pokazala je bolji uvid u u fizičke karakteristike parametara i značajniju objektivnost donosioca odluke u odnosu na metodu AHP.

Treatment of raw water in order to achieve quality requred for drinking water can be a major challenge, especially considering that raw water usually contains more than one pollutiant. With the advancement of water treatment technologies, especially membrane technologies, the efficiency of water purification has been increasing. The question is which technology is optimal, in terms of removal of pollutants, economic, environmental benefits and other criteria. Methods of multi-criteria optimization can provide significant assistence in choosing the optimal water treatment technology. In this paper, the VIKOR and AHP methods were applied for selection of optimal drinking water treatment scheme of water softening plant based on nanofiltration. The VIKOR method showed a better insight into the physical characteristics of the water quality parameters and a more significant objectivity of the decision maker in relation to the AHP method.
