| Summary: | The rubber industry, one of the major industrial polluters in Malaysia, is
discharging wastewater which contains much organic and inorganic matter from
various stages of process operations. Therefore, this study investigated the
effectiveness of effective microorganisms (EM) in an Anaerobic Sequencing Batch
Reactor (ASBR) system to treat rubber processing wastewater. Four different ratios
of EM/wastewater volume were used; 1:100, 1:500, 1:1000 and 1:2000. Chemical
oxygen demand (COD), biochemical oxygen demand (BOD5), turbidity and total
suspended solids (TSS) were analyzed in the wastewater. The treatment of
EM/wastewater ratio of 1:1000 successfully reduced up to 60% of COD, 62% of
BOD5, 62% of turbidity, and 84% of TSS. This system managed to reduce the
pollutants concentrations to the final COD concentration of 557 mg/L, BOD5
concentration of 226 mg/L, turbidity of 255 NTU and TSS concentration of 75
mg/L. It was found that the ratio of 1:1000 performed best to treat the sample.
Overall, this study suggested that EM technology in an anaerobic environment has
the capability of elevating the quality of the treated rubber wastewater. |
