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.

Dye-containing effluent generated in textile industries is polluting and complex wastewater. It should be managed adequately before the final destination. The up-flow anaerobic blanket (UASB) reactor application is an eco-friendly and cost-competitive treatment. The present study briefly reviews the UASB application for dye wastewater valorization. Bioenergy and clean water production potential during dye-containing wastewater treatment are emphasized to promote resource recovery in textile industries. Efficiencies of color and chemical oxygen demand of 50–97% and 60–90% are reported in bench-scale UASB studies. A biogas yield of 0.36–36.04 L d-1 in UASB, which treats dye-containing effluents, is documented. Bioenergy production and water reuse allow environmental and economic benefits. However, data on full-scale UASB treating dye wastewater are missing. Besides, studies on combined systems integrating membrane processes, such as ultrafiltration and nanofiltration, and pretreatment of wastewater and sludge for improvements in biogas production might realize the complete potential for resource recovery of UASB technology.

Dye-containing effluent generated in textile industries is polluting and complex wastewater. It should be managed adequately before its final destination. The up-flow anaerobic blanket (UASB) reactor application is an ecofriendly and cost-competitive treatment. The present study briefly reviews the UASB application for dye-containing wastewater valorization. Bioenergy and clean-water production potential during dye-containing wastewater treatment are emphasized to promote resource recovery in textile industries. Hydraulic retention time (HRT), organic loading rate (OLR), pH, temperature, and hydraulic mixing influence sludge granulation, microbial activity, and dye removal. HRT and OLR ranges of 6–24 h and 1–12 kg m−3 d−1 of chemical oxygen demand (COD) at a mesophilic temperature (30–40 °C) are recommended for efficient treatment. In these conditions, efficiencies of color and COD of 50–97% and 60–90% are reported in bench-scale UASB studies. Complex dye structures can hinder biomineralization. Pretreatment may be necessary to reduce dye concentration. Carbon-source and redox mediators are added to the UASB reactor to expedite kinetic reactions. A biogas yield of 1.48–2.70 L d−1 in UASB, which treats dye-containing effluents, is documented. Cotreatment of dye wastewater and locally available substrate could increase biogas productivity in UASB reactors. Organic waste generated in the textile industry, such as dye sludge, cotton, and starch, is recommended to make cotreatment cost competitive. Bioenergy production and water reuse allow environmental and economic benefits. Studies on combined systems integrating UASB and membrane processes, such as ultrafiltration and nanofiltration, for the production of reusable water and pretreatment of wastewater and sludge for improvements in biogas production might realize the complete potential for resource recovery of UASB technology. UASB bioenergy usage for integrated treatment trains can reduce operating costs and assist process sustainability in the textile industry.
