The high cost ultra-filtration method employed for the treatment of SCFs have made it mandatory to further modify the existing techniques so as to control the cost of waste disposal to the environment. The authors have proposed the use of agro-waste products <em>i.e.</em>, rice husk, bagasse, saw-dust and arhar stem (cajanus cazan) as adsorbents for removal of oil from SCF before they are finally disposed off into the environment. But it is very difficult to grade and select the best adsorbent without extensive experimental investigation. The utility of a multicriteria decision-making technique, called the Analytic Hierarchy Process (AHP), is explored in this study to select an appropriate adsorbent that satisfies the needs of the process. This paper presents the results of AHP for the selection and grading of adsorbents to be employed for the processing of SCFs.</p> <p>&nbsp;</p> https://ultraphysicalsciences.org/paper/1079/ Adsorbent Spent cutting fluid AHP Adsorption.
