Waste Removal Efficiencies of Floating Macrophytes for Restoration of Polluted Stream: An Experimental Analysis Bharati Mahajan, Sameer Shastri, Shreenivas Londhe Urban Science, 2023 Freshwater sources are affected by a diverse range of pollutants, which increases the demand for effective remediation. Aquatic phytoremediation is a nature-based solution. It has the potential to provide efficient, adaptable, and multi-targeted treatment of polluted waters. The aim of this research is to evaluate non-mechanized, low-cost onsite treatment of waste water intrusions. It includes an experimental set up with three replicates. Each consists of a modified flow pattern under outdoor conditions. Experimental set up A and B were provided with macrophytes, water lettuce and duckweed, respectively, with plant coverage at 50% and 90%. Experimental set up C was a controlled set up without macrophytes. The highest removal of BOD, COD and Total solids by using water lettuce were observed to be 89%, 77% and 38.5%, respectively. By using duckweed, the highest removal of BOD, COD and Total solids were observed at 88%, 66% and 27.59%, respectively. Removal was also observed in Set up C for BOD, COD and Total solids; its efficiency was 48%, 47% and 25%, respectively. Set up A can be recommended for treating wastewater intrusion, so that wastewater will purify to a to satisfactory to disposal standard level before mixing in river water. The area available in the stream itself can be used as a treatment zone.
Impact Assessment of Waste Water Streams on Water Quality of River Pavana in Pimpri Chinchwad City Area Bharati Mahajan, Sameer Shastri, Shreenivas Londhe 2021 International Conference on Computing Communication and Green Engineering Ccge 2021, 2021 Present research work was done for 23.2 Km stretch of river Pavana from Kiwale to Dapodi in District Pune, Maharashtra. In this research, discharge measurement was done for 19 waste water streams in Pimpri Chinchwad city area. These waste water streams are continuously disposing untreated waste water in River Pavana. Total pollutional load was calculated by using characteristic values such as Biochemical Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids along with the discharge measurement of waste water stream. Area velocity method was adopted for measurement of waste water stream discharge. BODmix and Degree of Treatment required were calculated for River Pavana. BODmix of river water of River Pavana (stretch from Ravet to Dapodi) was compared with raw water quality standards.
