Zero Liquid Discharge (ZLD) is a wastewater treatment process which is developed to completely eliminate all liquid discharge from a system by purifying and recycling the wastewater. This process leaves zero discharge at the end of the treatment cycle.Zero Liquid discharge is an advanced wastewater treatment that includes processes such as reverse osmosis, ultrafiltration, crystallization/evaporation, …

Zero, liquid ,discharge, (ZLD)—a ,wastewater, management strategy that eliminates liquid waste and maximizes water usage efficiency — has attracted renewed interest worldwide in recent years. Although implementation of ZLD reduces water pollution and augments water supply, the technology is constrained by high cost and intensive energy consumption. In this critical review, we discuss the ...

This work demonstrated nanoscale ,zero,-valent iron‘s efficacy as an enhancing element for remediating real mine water and pharmaceutical-containing ,wastewater, from a hospital. The laboratory-scale fluidized-bed reactor proved to simultaneously remove metal ions, like Mn and Zn, from ,wastewater, while achieving a significant reduction of SO 4 2− and organic matter (COD, BOD, DOC), TDN.
