This image presents the baseline water quality data for wastewater discharged from an apartment complex located in Johor Bahru, Malaysia. The analysis was conducted prior to any treatment processes. The results reveal significant exceedances of the Department of Environment (DOE) Standard B for several parameters, including Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), suspended solids, oil and grease, and ammonical nitrogen. These findings highlight the need for effective wastewater treatment to mitigate the environmental impact.
This image presents the post-treatment water quality data for wastewater discharged from an apartment complex located in Johor Bahru, Malaysia. The analysis was conducted after the wastewater had undergone a treatment process. The results reveal a substantial improvement in water quality, with most parameters now meeting the DOE Standard B. However, some parameters, such as COD and suspended solids, still slightly exceed the standard.
