Colour Removal with Adsorption Process Using Pomace
Journal Title: Cumhuriyet Science journal - Year 2017, Vol 38, Issue 4
Abstract
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.
