Aluminum, Al, is present in natural waters. It is hydrolyzing metal and comparatively insoluble in neutral pH conditions. However, under acid or alkaline conditions and/or in presence of complex agents its solubility changes, opening the possibilities for biochemical transformations. The ecological consequences are considered of increased concentrations of dissolved Al. Al in soil and water has various forms differing relative to the chemical and biological reactions. Al has always been considered a benign element. There are no indications of Al affecting the public health under normal conditions but too high doses of aluminum can cause serious health problems.
The effect of Al in water is described, e g. the Al salts which are generally used in the public water supply systems. The Al compounds are used as coagulates in the raw water treatment. The residual Al has always been low in the water. The paper presents the results of research on the application of aluminum polychloride.
The water purification process is optimized in relation to the values of the muteness and color of water and the amount of residual Al. Aluminum coagulants have significant advantages over other coagulants

Ključne reči: aluminum; nature; drinking water; coagulation.
