“…In wastewater treatment, energy consumption costs are one of the major costs [16]. For example, the electricity cost related to power resources in the treatment process can be 25-40% of the total operating expenses [17]. Energy usage also involves life-cycle environmental effects [18].…”

Reactive nitrogen (Nr) has become an essential nutrient to reclaim and recycle from wastewater. Nitrogen has become a valued resource that is beneficial to recover in the wastewater sector, as nitrogen is a key component in many fertilizers. The main subject of this work is to investigate the environmental consequences of a novel nitrogen recovery process from reject water. In our study, Life Cycle Analysis (LCA), PESTLE, and Multi-Criteria Decision Analysis (MCDA) were used to examine combining electroconcentration and stripping methods, including Monte Carlo simulation. Using SimaPro V9.3 software, the EF 3.0 Method, IPCC 2021 GWP100, ReCiPe 2016, and IMPACT World+ Endpoint were applied with heat and power, electricity high voltage, nuclear energy, and two renewable energies (solar and wind). EF 3.0 was endorsed by the European Commission for environmental footprinting. The operational unit of 1 m3 of reject water was chosen as the output, and “gate-to-gate” analysis was investigated. Our calculations show that the energies derived from natural sources reduce fossil-based environmental impacts and CO2 emissions significantly compared with conventional energy sources. A TOPSIS score was applied to appraise the choices in the case of MCDA. For the Australian territory, for the place of implementation of the technology, the most beneficial option was discovered to be wind energy offshore, with a score of 0.95, and the next was solar energy at 0.87.

Environmental pollution and climate change is the ultimate result of rapid urbanization. The change in environmental conditions due to undesirable human activities increases local ambient temperature hence it is leading to a rise in the river water temperature. Tapi river is the main source of drinking water for Surat city, Gujarat, India. A stretch of river Tapi has been studied from Kamrej to Causeway which has a stretch of about 22.39 km. The river water quality was found to be degraded due to the excessive discharge of pollutants from various points and non-point sources. Extreme discharge of pollutants into the river decreases the dissolved oxygen (DO) concentration. At the same time due to the increase in temperature, the process of transformation of atmospheric O2 gas into dissolved form also becomes very slow. In this study, the QUAL2Kw one - dimension water quality model was applied to assess the DO and BOD at various locations. The QUAL2Kw model was calibrated and validated with observed data. The calibrated model was applied to evaluate the effects of temperature on the DO and BOD of the Tapi river. The conditions of maximum, minimum, and average temperature for March, April, and May from the year 1991 to 2021 were considered. The result revealed that the full stretch of 22.39 km was not able to maintain minimum dissolved oxygen (DO) concentration, hence biochemical oxygen demand (BOD) has subsequently increased downstream of the river stretch. It was also observed that DO and BOD levels tremendously fluctuate ambient temperature.
