The reduction of oil pollutants of petroleum products storage-tanks sludge using low-cost adsorbents
Disposal of storage tank sludge in oil depots is a major environmental concern due to the high concentration of hydrocarbons involved.This paper investigates the reduction of the sludge oil pollutants with Tumbler initial oil and grease concentration of about 50 mass% using low cost adsorbents.Among the examined adsorbents, sawdust indicated the ma
