A comparative study of the performance behaviour of adsorbent materials used for the treatment of Spent Cutting Fluids

Abstract

The high cost ultra - iltration methods normally employed for the treatment of Spent Cutting Fluids (SCFs) has forced to develop effective technology for environmental pollution management. The authors have proposed the use of agro based products such as arhar stem (cajanus cazan), rice husk, bagasse and saw dust in modified and unmodified form as adsorbents for removal of oil from water based SCFs, replacing costly activated carbon. Analytical Hierarchy Process (AHP) was applied and the results were used to select and grade the adsorbents. The results have also been compared with the experimental results of the batch adsorption studies. Copyright © 2010 Inderscience Enterprises Ltd.
