Malaysia has represented as the fourth largest rubber producer in the world after Thailand, Indonesia and India
[1,2].The industry of rubber is one of the most important industries in Malaysia and plays a vital role in the nation’s
economy. There are two types of processes in raw natural rubber processing; the production of natural rubber latex
(NRL) concentrate and the Standard Malaysian Rubber (SMR) [3]. However, it must be noted that the production
process of the rubber industry always leads to a large amount ofcontaminated wastewater generated, as a result of large
quantity of water needed during processing. Untreated effluents from rubber industries are usually associated with
malodour problem and contain a considerable amount of contaminants and pollutants. Table 1 shows the typical
characteristics of effluents from rubber processing in
Malaysia. As the effluent consists of a complex mixture of
chemicals, high concentration of organic matters (major ions,
organic solvents, nutrients, etc.), suspended solids and
nitrogen, treatment of this wastewater under controlled
