Oncern [52]. The outcomes of the midpoint assessment of MBBR-MBR were also comparedMembranes 2021, 11,12 ofwith the earlier CAS study, shown in Table 11. MBBR-MBR demonstrated much more environmental benefits because its impacts had been the decrease in all of the categories, specifically in Climate Modify, Human Overall health, Marine eutrophication, Terrestrial ecotoxicity, Freshwater ecotoxicity and Marine ecotoxicity, because of the high good quality of the effluent treated by MBBR-MBR and the avoidance of using additional decolorizing agent.Table 11.

Conclusions The experimental study of a hybrid MBBR-MBR showed the effective removal of COD (93), colour (85) and TSS (99) with 1 day of HRT. The HRT reduction of 50 for the application of industrial scale is quite desirable, resulting in space and energy saving. Moreover, 100 of the water treated by the MBBR-MBR program accomplished new dyeings, representing 70 of the textile industry’s water consumption inside the dyeing approach. The value of CAPEX calculated for the hybrid MBBR-MBR method is 462,403 along with the raise in CAPEX is lucrative as a result of the reduction in OPEX, which benefits in reduce taxes and savings in decolorizing agent with regard to a tiny raise in electrical energy consumption. On top of that, the NPV and IRR study shows that water reuse soon after the remedy played an important part major for the cost saving of water consumption and discharge tax. The 18 of IRR calculated demonstrated that MBBR-MBR has great financial feasibility in industrial-scale textile wastewater remedy. Concerning the LCA study, because of the high efficiency in color removal, the hybrid MBBR-MBR program did not need the addition of decolorizing agent, which is a triamine that has a important effect on the environment. Hence, the results suggested that MBBR-MBR therapy generated a significantly decrease environmental impact than CAS treatment.Author Contributions: Investigation, X.Y.; Methodology, X.Y. and V.L.-G.; Project administration, V.L.-G.; Supervision, V.L.-G.; Writing–original draft, X.Y.; Writing–review editing, V.L.-G.
