A model and mathematical representation for membrane concentration and purification of macromolecular solutions containing low molecular weight contaminants

摘要: Abstract A process model of simultaneous concentration and purification marcomolecular solutions containing low molecular weight contaminants is suggested. This considered to occur with the help ultrafiltration. Macromolecules are retarded by membrane, forming a gel layer, filter through formed cake. mathematical description layer formation contaminant rejection as function macromolecule concentrations The basic physicochemical parameters determining all features interaction potentials between membrane frame contaminants, on one hand, other. obtained equations should enable researchers analyse above mentioned process.
