ABSTRACT
The aim of the study is to choose the variant of design optimization of existing drinking water treatment plant by Life Cycle Assessment (LCA) tool. This plant is located in the Chelyabinsk region of Russian Federation. In this LCA we compared two water treatment technologies: conventional system and ultrafiltration (UF) with ozonation – activated carbon pretreatment. The software Sima Pro 8.0.2 has been used as the LCA analysis tool. Eco-Indicator 99 method has been applied. The results show that the UF is characterized by the high consumption of electricity. In conventional technology the electricity consumption is seen as efficient, but its chemical usage is seen as the major contributor to the reduction of environmental quality and human health.

Keywords: Life Cycle Assessment (LCA), water treatment plant, drinking water, conventional water treatment, ultrafiltration (UF)
