Abstract
The feasibility of foam separation as a technique was assessed for the recovery of potato protein from the simulated potato processing waste effluent (SPWE). The effects of initial protein concentration, pH, air flow rate ,liquid loading volume on separation performance were examined by using a foam fractionation column with partial horizontally flowing foam phase. Based on the comprehensive consideration of effect on the enrichment ratio and the recovery percentage, the optimal conditions were initial protein concentration 0.5 g/L, initial pH 4.0, air flow rate 62.5 L/h ,liquid loading volume 200mL, Under the conditions, a greater enrichment ratio of the protein of 9.1 was obtained with a recovery percentage of the protein of 84.3%.The research are aimed at laying a foundation for the industrialization of recovering potato protein from the wastewater by foam separation.
