Abstract
The efficiency of the wastewater treatment is highly influenced by the characteristics of incoming raw wastewater into the treatment plant. The improper design resulted in inefficient treatment, of which consequently leading to the pollution and contaminant release to nearby water streams. High concentration of untreated or inefficiently treated effluent poses significant impacts to the health of both human and aquatic life. Wastewater characteristics based on real-time monitoring measurement in a catchment area, in particular at the inlet chamber of a sewage treatment plant (STP) not only provides precise data and information of pollutant loading behavior but also hypothesis the lifestyle and waste habit in the specific locations. In this research, the parameters of Chemical Oxygen Demand (COD) and Ammonia Nitrogen (NH3-N) incoming raw wastewater samples were temporally monitored. The measurement campaign was conducted at two locations, at a Network Pumping Station (NPS) and connected STP with Population Equivalent (PE) of 1000 and 60000, respectively. The temporal variation for COD shows a regular pattern with distinct peaks, i.e., at morning and evening were identified. However, no temporal variation was observed for parameter NH3-N. The strength of the wastewater influent has a fairly low concentration of COD between 57 mg/L to 313 mg/L at NPS and 117 mg/L to 612 mg/L at STP. This value is lower than the commonly influent designed STP of COD concentration at 500 mg/L (Malaysian Sewerage Industry Guidelines (MSIG), Volume IV, Section 3). Comparison of wastewater pattern with temperate climate of South Korea showed a discrepancy in terms of peak time and concentration pattern.
