AbstractThe factory "A" is a small scale Ribbed Smoked Sheet industry, located in Songkhla, Thailand. The average production of ribbed smoked sheet is I .5 tons RSS/ day. The average water consumption is 3.38 m3 / ton field latex and producing 3.82 m3 wastewater. The wastewater contains high organic of rubber composition and chemical used in the processing. Characteristic of wastewater are 2,250 mg/L BOD, 3,427 mg/L COD, I26 mg/L TKN, I3.5 mg/L NH3-N, 2I mg/L TP, 20 mg/L Sulfate, 280 mg/L SS, 5.,708 mg/L TS and pH 4.7-5.0. The fluctuate flow rate of wastewater enter to treatment plant depend on amount of field latex supplied to the factory. The existing wastewater treatment system comprised of I -anaerobic pond, I-aerated lagoon, and I-polishing pond but the system is failure because an area that the factory located has no electricity and there have not treatment plant operator or the worker who has knowledge about their treatment system. The effluent from the treatment plant is not met Thailand industrial effluent standard. Laboratory scale experiment of aerated lagoon system and waste stabilization pond system was conducted to investigate the efficiency of both systems to treat wastewater from Ribbed Smoked Sheet factory. The result of laboratory scale experiment, efficiency of aerated lagoon is 98.4% BOD and 96.0% COD removal at 4 days HRT. And the efficiency of baffle waste stabilization pond is 96.2% BOD and 93.0% COD removal at I5 days HRT. In this study to improvement the treatment plant, baffle waste stabilization pond system was used instead of aerated lagoon system in the existing treatment plant. This will be an option to reach effluent standard and wastewater can be reused in the production line to reduce water consumption in the factory. How to recycle the water from the treatment plant should be transferred to the operator together with the monitoring of treatment system
