The elimination of trace arsenic via hollow fiber supported liquid membrane: experiment and mathematical model

Abstract This work presents the elimination of arsenic ions from synthetic produced water via hollow fiber supported liquid membrane (HFSLM). Results demonstrate that arsenic ions in synthetic wastewater can be successfully treated to meet the wastewater standard as formulated by the Ministry of Ind...
