Pollution Assessment of Carwash Effluent in Daily Load System
In Malaysia, effluent discharged are measured in terms of concentration (mg/l), however Malaysian rivers quality are continue to decline. Pollution loading had been implemented in modern countries and its approached is to measured pollution discharges in terms of daily loading. This method has proven to revitalise their river quality hence it can be implemented in Malaysia to rejuvenate its current situation. This study, a carwash is subjected for pollution assessment and pollutions are measured in both concentration and loading. Results of carwash pollution discharged in term of concentration comply with guideline by Environmental Protection Agency (EPA) of United States of America (USA). This result might be misleading for the pollution contribution factor. Further evaluation of the carwash wastewater pollution characteristic in term of pollution loading have given a new perspective of the real situation. On highest rate of wastewater discharged, the loading for COD, BOD, TSS, O&G and TP each contribute 1.36574856 kg, 0.30027096 kg, 0.10654776 kg, 0.068578013 kg and 0.000193723kg n a day. These results demonstrated that a single car wash premise discharged can potentially bring harm if disposed directly into river systems.

Abstract
In Malaysia, effluent discharged are measured in terms of concentration (mg/l), however Malaysian rivers quality are continue to decline. Pollution loading had been implemented in modern countries and its approached is to measured pollution discharges in terms of daily loading. This method has proven to revitalise their river quality hence it can be implemented in Malaysia to rejuvenate its current situation. This study, a carwash is subjected for pollution assessment and pollutions are measured in both concentration and loading. Results of carwash pollution discharged in term of concentration comply with guideline by Environmental Protection Agency (EPA) of United States of America (USA). This result might be misleading for the pollution contribution factor. Further evaluation of the carwash wastewater pollution characteristic in term of pollution loading have given a new perspective of the real situation. On highest rate of wastewater discharged, the loading for COD, BOD, TSS, O&G and TP each contribute 1.36574856 kg, 0.30027096 kg, 0.10654776 kg, 0.068578013 kg and 0.000193723kg n a day. These results demonstrated that a single car wash premise discharged can potentially bring harm if disposed directly into river systems.
