Lau C. M., . Concentration of natural rubber serum by reverse osmosis. pp. 226-240. ISSN 1511-1768
Abstract
A preliminary investigation was made into the well-known process of reverse osmosis (RO) for its possible use to concentrate the serum (NRS) that is derived from the coagulation of various types of natural rubber latices. The results showed that concentrated NRS with a maximum total solids content of about 12 (w/w) could be obtained using up to 50 bars of pressure. The maximum concentration factors obtained were about 3.8 whilst the maximum recoveries were around 87. Membrane fouling and the poor quality of the resultant permeates which were also observed suggest that the aromatic polyamide membrane material used in the RO equipment was not suitable for NRS.
