Abstract

The aim of this study was to determine the effects of alkaline fly ash on fecal coliform content of wastewater sludge. In addition, the variation of fecal coliform numbers in fly ash-sludge mixtures during drying process was observed. The results of the study indicated that addition of fly ash with doses of 40%, 80% and 120% (on a dry weight basis) was not adequate for an efficient removal of pathogens. Drying fly ash-sludge mixtures to 40% dry matter wasn't suffecient in terms of fecal coliform reductions, where as drying to 60% dry matter achieved 1-2 log fecal coliform removal. It was determined that drying to approximetely %90 dry matter brought about a reduction in indicator bacteria ranging from 3 to 5 logs.

Özet

Bu çalışmada, arıtma çamurlarına ilave edilen alkali karakterli uçucu külün çamurun fekal koliform içeriği üzerindeki etkilerinin ortaya konması amaçlanmıştır. Ayrıca, hazırlanan çamur-uçucu kül karışımlarının indikatör bakteri sayılarında kurutma süresince meydana gelen değişimler izlenmiştir. Çalışma sonuçlan %40, %80 ve %120 (kuru ağırlık bazında) oranlarında eklenen uçucu külün yalnız başına etkili bir patojen giderimini sağlayamadığını göstermektedir. %40 kuru madde seviyelerine kadar kurutulan kül-çamur karışımlarında etkin bir fekal koliform giderimi sağlanamazken, %60 kuru madde seviyelerine kadar kurutulan karışımlarda l ila 2 logluk bir azalma, gerçekleşmiştir. %90 kuru madde seviyelerine kadar kurutulan örneklerde ise indikatör bakterilerin 3 ila 5 loğ azaldığı tespit edilmiştir.
