The constructed wetland (CW) in Gra

The constructed wetland (CW) in Gradig~e (Slovenia) has been in operation since 1991 for the
purification of waste waters from a food processing plant. It functions according to the method of
horizontal subsurface flow. Waste waters are composed of industrial, faecal and meteor waters. The CW
is composed of two beds, filled with substrate and planted with Carex gracilis and Phragmites australis.
Average hydraulic loading of the CW is 5 m 3 d-k A high COD average value of 3674 mg 1 -t and a BOD5
average val~Le of 962 mg 1-t are characteristic of influent waters. Analysis showed that pollution decreased
with regard to COD by 92%, BOD5 89%, orthophosphate 96%, ammonium 86% and nitrate 65%. The
microbiological parameters indicated that the total number of coliform bacteria is reduced by 99% and
the number of faecal streptococci by 98%. Results demonstrated that the CW can be appropriate for
treating waste waters from the food processing plants
