Application of Sequential Combination of Electro-Coagulation/Electro-Oxidation and Adsorption for the Treatment of Hemodialysis Wastewater for Possible Reuse

Reusing hemodialysis wastewater (HWW) is more difficult due to its higher conductivity (salinity) and the need for an iterative RO or adsorption process. It can therefore be challenging technologically laborious. In this context, study aimed investigate possibility of treating HWW by combining electro-coagulation (EC) electro-oxidation (EO) processes as best technologies achieve efficient removal dissolved micropollutants. work, application electro-coagulation/electro-oxidation using, respectively, aluminum platinum electrodes combined with onto active carbon treat was studied. EC process, high phosphate ions chemical oxygen demand (COD) observed. EO COD performance, total nitrogen, Mg were significant reached 100, 83, 89%, after 100 min treatment. The estimated energies required and/or approximately 0.7 kWh/m3 0.05 kWh/m3, respectively. While used from showed almost similar performances, process seems consume less energy. Therefore, electrochemical successfully performed using activated (AC) complete mineralization pharmaceutical residues. experimental results that coupling three (EC–EO–AC) provides treated water reused in agriculture sodium absorption ratio (SAR) value might alternative method treatment responding concept green dialysis.
