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
