Özet
Zeytin ve zeytinyağı özellikle Akdeniz ülkelerinde üretilen önemli tarım ürünleridir. Türkiye'de Ege, Marmara, Akdeniz, Güneydoğu Anadolu Bölgeleri'nde zeytin ağacı yetiştirilmektedir. Bu kadar geniş bir uygulama sahasına sahip olan zeytin endüstrisinin faaliyetleri sırasında oluşan bazı üretim atıkları bulunmaktadır. Zeytin ağacı yetiştirme sırasında her ağacın yıllık yaklaşık 25 kg'a kadar yan ürün (çerçöp, dal, yaprak vb.) oluşturduğu tahmin edilmektedir. Zeytin atığı ürünlerinin tip ve miktarı üretim teknolojileri ve çalışma verimliliğine göre değişim göstermektedir. Zeytinin ağaçtan toplanıp zeytinyağı elde edilene kadar geçen süreçte elde edilen zeytin yaprakları, dalları, pirina ve karasu temel yan ürünlerdir. Endüstriyel faaliyet sırasında ise çekirdek, kabuk ve posa gibi materyalleri içeren atığa da pirina denilmektedir. Yağ ekstrakte edilirken uygulanan prosedüre göre elde edilen pirinanın da nem ve yağ içeriği değişmektedir. Deneylerde ise kuru halde hazırlanmış pirina kullanılmıştır.Bu çalışmada laboratuvar ortamında hazırlanan Everzol Yellow 3RS içeren sentetik atıksudan adsorban madde olarak zeytin atığı (pirina) kullanılarak renk giderimi araştırılmıştır. Adsorbanın etkinliğini kanıtlayabilmek üzere süreye, doza, hıza, sıcaklığa ve pH'ya bağlı olarak optimum denge şartları belirlenmiştir. Adsorpsiyon işlemleri neticesinde 150 dakika temas süresi, 250 rpm karıştırma hızı, pH 7,5 ve 25 0C sıcaklık değerlerinde adsorban/boya oranı olarak 0,6 g/250 mL (%80'nin üzerinde giderim) elde edilmiştir
Olive and olive oil are important agricultural products produced especially in Mediterranean countries. Olive tree is grown in Aegean, Marmara, Mediterranean and Southeastern Anatolia regions in Turkey. Some production wastes are caused by the activities of olive industry which has a rich application area. It is estimated that in the course of growing, each olive tree annually generates about 25 kg of by product (sweeps, branches, leaves etc.). The type and amount of Pomace products vary according to production technologies and work productivity. In the process starting from the picking up of olives from the tree to the production of its oil, the basic emergent by products are olive leaves, branches, pomace and wastewaters of olive oil. The waste which includes materials such as seed, crust, pulp in the course of industrial activities is also called pomace. The humidity and olive content of the pomace obtained varies according to the procedure applied in the extraction of oil. In the experiments, dry-prepared pomace was used In this study colour removal was examined from synthetic color wastewater containing Everzol Yellow 3RS prepared in laboratory process by using pomace as an adsorbent. In order to prove the effectiveness of the adsorbent, optimum equilibrium conditions was determined dependently on contact time, dosage, speed, temperature and pH. As a result of adsorption processes, 150 min. contact time, 250 rpm mixing speed, pH 7,5, 25 0C temperature and 0,6 g/250 mL adsorbent/dye ratio (over 80% removal efficiency) were determined.
