Reducing of biodiesel wastewater by hexane extraction process

Key words: Extraction; Wastewater; KOİ; Oil grease; Biodiesel; Hexane In this study we investigated that biodiesel from wastewater may be reduced by hexane extraction process. KOI, Oil grease, pH have been checked on the samples after the samples had been taken at specific times. In our experimental study, it has been analyzed effect of these parameters on KOI, Oil grease, KOI % capacity, Oil grease by changing of amount of temperature, pH and KMnO4 parameters. To reduce effectively KOI and Oil grease in the wastewater, KMnO4 and hexane have been used. The reducing capacity couldn`t be obtained effectively because prior KOI and Oil grease had amount of very much concentration (70 %). At the first chapter meaning and importance of study has been explained. At the second chapter information about biodiesel has been given. At the third chapter reducing process and characteristics of biodiesel wastewater have been explained. At the fourth chapter in part of material and method experimental studies and designations had been explained. At the fifth chapter experimental results with chart and graphic have been showed. Also of some parameters, reducing effect on KOI and Oil grease has been mentioned. At the sixth chapter results have been explained. At the seventh chapter discussions and suggestions about studies have been represented.
