Influence of cleansers on a polysulphone membrane used for milk ultrafiltration

Abstract

Membrane stress and apparent water flux were measured as a function of time, pressure and milk concentration during unstirred ultrafiltration of milk with a polysulphone membrane. Membrane properties changed considerably after exposure to six common membrane cleanser's with notable changes in the rate of declines in milk flux (Q), increase (inorganic and organic cleansers) and decrease (surfactants) in relative hydraulic resistance (RHR) values.

Concentration of Omega‐3 polyunsaturated fatty acids by polymeric membrane

“…With the advent of membrane technology, separation, concentration and purification have become industrially feasible unit operations because of the lower energy requirement, high efficiency of separation, working at low temperature and simplicity of operation (Kumar & Bhowmick, ; Abedini et al ., ; Dorosti et al ., ). Among the various types of membranes, polymeric membranes have been widely used in processes due to lower operating cost, more flexible properties and ease of fabrication (Nwuha, ; Abedini et al ., ). Application of membrane separation processes in the oil and fat industry has increasingly gained interest (Vaisali et al ., ).…”
