Występowanie związków organicznych w wodach górskich i ich podatność na koagulację

The problem of mountain water treatment is still raising great interest both in this country and abroad. Mountain water calls for treatment by enhanced coagulation not only because of high coloured matter content and turbidity, but also because of high organic substance concentrations which affect the efficiency of disinfection. This undesirable effect persists even if other pollutants do not exceed the admissible levels. In the present paper, consideration is given to seasonal variations of organic matter (including THM precursors) in the "Wisła-Czarne" reservoir, which stores mountain waters. On the basis of statistical analysis, attempts are made to correlate organic matter concentration (expressed as UV254], colour, COD and TOC. Making use of measured UV254 and TOC values, the susceptibility of the water to treatment by enhanced coagulation is assessed.
