conditions is necessary in order to prevent the release of harmful wastes to the environment. Stringent environmental regulation for the control of rubber effluents is enforced in Malaysia in which the wastewater treatment plant must comply with the Environmental Quality (Industrial Effluents) Regulations 2009 under standard A and standard B. Both standards consist of discharge temperature, pH, biological oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS) and other heavy metals, but with different parameter limits, depending on the location of discharge after treatment process. With a new global trend towards a sustainable development, the rubber industry needs to focus on cleaner production technology, waste minimization, utilization of waste, resource recovery and recycling of water. Among various treatment approaches, biological methods especially aerobic, anaerobic and facultative ponds are widely used for treatment of rubber wastewater in Malaysia [2]. These systems are inexpensive and have a high efficiency for organic load reduction, but required large areas to implement. Recently, membrane based separation processes have
