Bu çalışmada Balıkesir'in Edremit ilçesinde üç fazlı sisteme göre zeytinyağı üretimi yapan bir fabrikanın atıksularının (karasu) fiziko-kimyasal arıtılabilirliği araştırılmıştır. İncelenen karasuda öncelikle asit kraking işlemi yapılarak yağlı kısmın atıksudan ayrılması sağlanmıştır. Bu işlem sonucunda KOİ'de %53, AKM'de %91, fenolde ise %31 oranlarında giderim sağlanmıştır. Daha sonra asit kraking çıkışından alınan atıksuda, Chitosan, SDS (Sodyum dodesil sülfat) ve FeCl3 kullanılarak kimyasal arıtma yapılmıştır. Kimyasal arıtılabilirlik çalışması neticesinde ise, pH=6'da, 50 mg/L Chitosan, 0,6 g/L SDS ve 2500 mg/L FeCl3 dozlarında, KOİ'de %68 oranında giderme verimi elde edilmiştir. Bu arıtılabilirlik çalışmasına göre, karasuyun KOİ değeri 128000 mg/L'den 19200 mg/L değerine %85'lik bir verimle indirilebilmiştir. Karasuyun SKKY'nde verilen deşarj kriterine kadar (KOİ=230 mg/L) arıtılabilmesi için, fiziko-kimyasal arıtmadan sonra ileri arıtma tekniklerine ihtiyaç duyulduğu düşünülmektedir.
