Abstract:
As the urban population and urbanization and industrialization are growing at a very high rate the municipal wastewater generation is causing a high pressure on the existing sewage treatment infrastructure. Effective wastewater treatment is critical to safeguard people's health, maintain aquatic ecosystems and sustain water resource management. Hydraulic detention time (HDT) is one of the key operational parameters to consider in determining the amount of physical, chemical and biological pollutants that can be removed from a sewage treatment plant (STP). The contact time between wastewater and microorganisms in treatment units is determined by the hydraulic detention time which affects degradation efficiency, sedimentation characteristics, nutrient removal and the stability of the plant. The present research is experimental study of the effects of hydraulic detention time of the sewage treatment plant on treatment efficiency and pollutant removal under different operating conditions. The study will emphasize the removal characteristics of the most important wastewater quality parameters, namely Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Nitrogen (TN), ammonia, and phosphorus at different detention times. The research is conducted on the field and in the lab employing standard research methods and procedures. Under varying detention times, wastewater samples are taken from the effluent and influent portions of the treatment system at regular intervals to assess treatment efficiency and stability. The experimental observations are used to analyze the relationship between detention time and pollutant removal efficiency. Comparative analysis is carried out to determine the optimum detention time range that will give the best performance of the treatment plant without any change in the operational requirements. The study also assesses the pollutant removal as well as operational parameters like sludge settling behaviour, aeration efficiency and effluent quality uniformity under varying hydraulic conditions. The study also looks at the impact of under- or over-detention time on treatment reliability and process efficiency.
