However, its implementation faces non-technical challenges, need collaborate with new stakeholders face societal acceptance issues. Looking at prominence circular economy in current policy developments challenges resource recovery, exploring these issues is urgently needed. In this work, we reviewed broad range literature identify values relevant other resources from wastewaters, particularly urban industrial wastewater desalination brines. We discuss tensions uncertainties around values, such tension between socio-economic expectations potential long-term sustainability impacts, well regarding safety regulations. For addressing uncertainties, suggest aligning common methods engineering natural sciences Responsible Innovation approaches, Value Sensitive Design Safe-by-Design. To complement Innovation, social learning Sustainability Transitions or Adaptive Governance perspective suggested.

Textile industry is one of the major water-consuming sectors; therefore, developing methods for reusing water essential. Processes including reverse osmosis (RO) have gained momentum recently and been widely used. However, concentrated streams (brine) generated from RO must be managed properly. In this study, a pilot-scale brine treatment system containing ozone oxidation, nanofiltration (NF), ion exchange (IEX) was developed operated to recover high quality process salt solution reused in dyeing processes. It revealed that 77% 66% (as NaCl) can recovered discharge reduced. With full-scale operation year, it possible achieve cost-savings by 176,256 USD with 115,000 m3 37,000 680 tons NaCl.

Desalination is an energy intensive process requiring adequate pre- and post- treatment. The novelty of this paper that it jointly reviews the technologies for pre-treatment, desalination post-treatment bridges gap between them while comparing treatment methods needed depending on type feed water including seawater, brackish water, municipal industrial wastewater. Those different streams show wide variability, sometimes containing organics, oil or scaling precursors which require Nowadays, membrane pre-treatment have become promising alternatives to conventional techniques thanks their flexibility. Hybrid shown great potential in reducing consumption. Moreover, plants produce large quantities brines reduce environmental impacts. Current research looking into recovering salts, metals potable from achieve zero liquid discharge (ZLD). Thermal-based ZLD are capable extracting those resources membrane-based mostly limited pre-concentration recovery due fouling issues.

In recent decades, freshwater reserves have been under high threats, generated mainly by anthropogenic causes such as rapid population growth and climate change. Currently, one of the technologies that has used to meet global demand is seawater desalination. However, this solution two major drawbacks. First, discharge reject brines with a concentration pollutants nitrates, causing environmental problems eutrophication processes. Second, desalination systems, both membrane thermal technologies, energy consumption supplied fossil fuels, contributing emission greenhouse gas. Recently, solve problems, zero —or minimal— liquid strategy emerged.
