Uzyskanie wody o jakości odpowiadającej wymaganiom stawianym wodzie przeznaczonej do spożycia i na potrzeby gospodarcze jest podstawowym zadaniem procesu uzdatniania wody. Doboru sposobu uzdatniania wody dokonuje się na podstawie takich kryteriów jak: jakość wody w stanie surowym, skład domieszek czy zanieczyszczeń i docelowa jakość wody. Rosnące wymagania wymuszają stosowanie skomplikowanych procesów, co skutkuje coraz większą ilością odpadów i popłuczyn o różnym stopniu szkodliwości.

An increased awareness of the presence of toxic contaminants in water treatment residuals is observed. The chemical composition of sludge predominantly depends on: type of water: fresh or groundwater, type and concentration of chemicals contained in raw water, composition and doses of treatment chemicals, the effects of water treatment process determined by type and quantity of removed mixtures and type and concentration of by-products of chemical reactions occurring during water treatment process. The contaminants of reagents used may significantly influence the quality of residuals from water treatment plant. An overview of the chemical characteristic and hazardous properties of waste produced during treatment process employed is presented. The choice of procedure of utilization or land disposal of water treatment sludges require as the first step that sludge has been shown to be nonhaz- ardous. It means, that water systems should thoroughly test their residuals prior to making disposal decision.
