Approximately about 41.7% water that should be in free of charge was contained in the oily waste that company paid.This was caused by lack of operator’s knowledge, unavailable measurement device in the field as well as lack of Standard Operating Procedures. The project team also identified the optimal process to improve the water content.By the end of the project, project team had successfully improved the water content to 19.5% in average.
