Concentration of NR field latex using tubular cross flow ultrafiltration system

Devaraj Veerasamy, . and Nik Meriam Sulaiman, . and J. Nambiar, . and Yusof Aziz, . Concentration of NR field latex using tubular cross flow ultrafiltration system. pp. 12-35. ISSN 1511-1768

This study presents an alternative method of concentrating field latex (FL) that produced latex concentrated and a clear serum as a by-product. The serum obtained could be utilised for the extraction of useful biochemicals; and as it was not contaminated by sulphuric acid value-added products from waste could also be obtained. A tubular cross flow ultrafiltration system one of the pressure-driven membrane separation techniqes was used to examine the concentration process of FL. A suitable preservation system to increase the stability of latex to withstand mechanical shear stresses during ultrafiltration was investigated. Fouling of membrane could be reduced by a cleaning-in-place (CIP) technique and also by adopting suitable cleaning protocols. Results showed that FL with a suitable composite preservation system could be concentrated from 30 DRC to 46 DRC by applying CIP with transmembrane pressure of 2.5 bar.

Abstract

This study presents an alternative method of concentrating field latex (FL) that produced latex concentrated and a clear serum as a by-product. The serum obtained could be utilised for the extraction of useful biochemicals; and as it was not contaminated by sulphuric acid value-added products from waste could also be obtained. A tubular cross flow ultrafiltration system one of the pressure-driven membrane separation techniqes was used to examine the concentration process of FL. A suitable preservation system to increase the stability of latex to withstand mechanical shear stresses during ultrafiltration was investigated. Fouling of membrane could be reduced by a cleaning-in-place (CIP) technique and also by adopting suitable cleaning protocols. Results showed that FL with a suitable composite preservation system could be concentrated from 30 DRC to 46 DRC by applying CIP with transmembrane pressure of 2.5 bar.
