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 initial oil and grease concentration of about 50 mass% using low cost adsorbents.Among the examined adsorbents, sawdust indicated the maximum re
