Treatabılıty of Oıly Wastewater and Desıgn of the Treatment System

Öz

The oily wastewater depending on the source, has a very complex composition, such as suspended and dissolved solids, organic salts, oil and grease, aliphatic and aromatic hydrocarbons, sulfides and metals. Because of this content, it poses a danger to land, water, air and human life. Therefore, oil wastewater treatment has become a problem requiring urgent solution, and studies on treatment techniques have recently gained momentum. Many methods such as electrochemical treatment, membrane filtration, biological treatment and hybrid technologies are used for the treatment of oil-containing wastewater. Electrochemical treatment, membrane filtration, biological treatment, hybrid technologies are some of these methods. The aim of this study is to design a chemical and biological treatment system that will provide the discharge limits by determining the chemical treatability of the wastewater from a fuel storage facility. According to the results of the research, COD removal efficiency was determined as 94%, suspended solids removal efficiency was 96% and oil grease removal efficiency was 98% after treatment with acid cracking, dissolved air flotation and activated sludge system.

PETROL İÇEREN ATIK SULARIN ARITILABİLİRLİĞİ VE ARITIM SİSTEMİNİN TASARLANMASI

Öz

Petrol içeren atık sular, tehlikeli içeriği nedeni ile toprak, su, hava ve insan hayatına karşı bir tehlike oluşturmaktadır. Petrol endüstrisinden kaynaklanan atık suyun arıtım teknikleri konusundaki çalışmalar son zamanlarda hız kazanmıştır. Bu nedenle, petrol atık suyu arıtımı acil çözüm gerektiren bir problem haline gelmiş olup, acilen araştırılması ve çözüm bulunması gerekmektedir. Petrol içeren atık suyun arıtılması için pek çok yöntem uygulanmaktadır. Elektrokimyasal arıtım, membran filtrasyonu, biyolojik arıtım, hibrid teknolojiler bu yöntemlerden bazılarıdır. Bu çalışmanın amacı,  bir akaryakıt depolama tesisinden kaynaklanan atık suların kimyasal  arıtıla bilirliğini belirleyerek, deşarj limitlerini sağlayacak bir kimyasal ve biyolojik arıtma sistemini tasarlamaktır. Araştırma sonuçlarına göre asit kraking, çözünmüş hava flotasyonu ve aktif çamur sisteminden oluşan arıtma sisteminin ardından KOİ giderim verimi %94, askıda katı madde giderim verimi %96 ve yağ gres giderim verimi  %98 olarak tespit edilmiştir.
