Abstract
The aim of this study is to quantify the water-energy-emissions nexus in wastewater treatment plants (WWTPs). At first, energy auditing is done for two real WWTPs to find out the energy consumption of different plant stages and the energy-saving potentials. The power plant and carbon capture units are taken into account to assess the energy-emission nexus based on emergy flows. Then, the emergy analysis is applied to evaluate the environmental, economic and technical aspects. An emergy performance index (EmIGHG) is presented by the means of emergy flow diagram of the WWTP beside a power plant (considering the electricity production emergy cost) and carbon capture unit (considering the CO2...

Abstract
Herein, a magnetic zirconium-based metal-organic framework nanocomposite was synthesized by a simple solvothermal method and used as an adsorbent for the removal of direct and acid dyes from aqueous solution. To enhance its adsorption performance, poly(propyleneimine) dendrimer was used to functionalize the as-synthesized magnetic porous nanocomposite. The dendrimer-functionalized magnetic nanocomposite was characterized by field-emission scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, nitrogen adsorption/desorption isotherms, and vibration sample magnetometer. The obtained results revealed the successful synthesis and functionalization of the...
