Abstract

The phyto-zooplankton composition and some physical and chemical properties of drinking water were investigated in the İvedik water treatment plant. The mean values of phytoplankton abundance were 641±92 and 438±55 ind/ml in the Kurtboğazı and Çamlıdere inlets, respectively. More than 50% of the phytoplankton belonging to the classes Bacillariophyceae, Chlorophyceae, Cryptophyceae and Dinophyceae were removed in the clarifiers. The treatment efficiency of phytoplankton ranged from 89 to 100% after the last chlorination. The mean values of zooplankton abundance were 93±23 and 59±18 ind/l in the Kurtboğazı and Çamlıdere inlets, respectively. The treatment efficiency of zooplankton varied between 97% and 100% in the balancing room. In processed water, phytoplankton (Tetrachlorella, Cyclotella, Gomphosphaeria, Anabaena, Staurastrum, Aphanizomenon, Botryococcus and Rhodomonas) were recorded. In addition, zooplankton (Keratella, Ascomorpha, Polyarthra and nauplii) were found in treated water.
