Abstract

Recently, a lot of domestic wastewater is being generated due to the rise in the population in most urban areas in Malaysia. This implies that more contaminations are being produced which are likely to affect human health. The purpose of this research was to analyze the level of contaminants in the final treated wastewater from the sewage treatment plants in Malaysian urban areas and compare it with Malaysian standard A and B effluent discharged. The specimens used for the analysis were obtained from three wastewater sewage treatment plants in Johor (A), Kuala Lumpur (B), and Penang(C). Specimens were examined using chemical oxygen demand (COD) Vials, Nitrate Nitrogen ammonia vial, and total Phosphorus vial. The Hach DR 5000 UV-V Laboratory Spectrophotometer was used to measure the amount of COD, Nitrate, Nitrate, and Phosphorus. Also, the pH, turbidity, and BOD5 were done utilizing dissolved Oxygen machine and Lovibond Turbidity Meters. The level of BOD, COD were treated well and discharged according to the used standards. The findings revealed that phosphorus in plant c with 12 mg/L in February, Nitrate in plant A 22 mg/L in January, Nitrite in plant A with 18.2 mg/L in February, 19.4 mg/L in February in plant B and16 mg/L in February were found little greater than the prescribed effluent standard of Malaysian wastewater. It was recommended that the final treated water should be frequently and thoroughly treated for the purpose of reusing it for secondary intent. This study has important implications for protecting human health and the environment by identifying the effluent sewer treatment plant that has no proper treatment capability to produce water that is fit for domestic and irrigation purpose.
