Bu çaly?mada, fenton, fenton-benzeri ve potasyum permanganat kullanylarak olu?an a?yry çamur miktarlaryndaki azalmalar tespit edilmi?tir. Bunun yanynda kullanylan kimyasallaryn çyky? suyu kalitesine ve çamur karakteristi?ine olan etkileri belirlenmi?tir. Ayryca, daha önceden ozon ve klorla yapylan çaly?malarda kullanylan konsantrasyona denk konsantrasyonlarda çaly?yldy?yndan elde edilen sonuçlaryn bunlarla kar?yla?tyrmasy da yapylmy?tyr. Fenton yöntem ile % 80, fenton benzeri yöntem ile % 75 ve potasyum permanganat ile % 75'lik çamur azalmasy elde edilmi?tir. Fakat, çyky? suyu kalitesi ve çamur karakteristi?inin bozuldu?u gözlenmi?tir. Maliyet ve çamur azalmasy verimi dikkate alyndy?ynda, a?yry çamur azalmasynda fentonun ozon ve klor yöntemine alternatif oldu?u bulunmu?tur.

In this study, fenton, fenton like and potassium permanganate was used for excess sludge elimination. The effect of these chemical oxidants on sludge reduction, effluent water quality and sludge characteristics were investigated. Besides, the obtained results were compared with studies made by using ozone and chlorine because of the same concentrations were used. Sludge minimization was found as 80 % for fenton, 75 % fenton like and 75 % potassium permanganate. However, effluent water quality and sludge characteristics worsened. It is found that fenton is able to replace the ozonation and chlorine in term of excess sludge reduction and cost.
