“…To study this process, this study started with a 2 L ⋅ min −1 inflow to match the pilot‐level studies. In addition, the EO reactor was considered to have a flow of 2.4 L ⋅ s −1 ; this flow was obtained in a previous study while treating wastewater containing AMX [20] …”

“…In this study, the configuration of the modular system of the pilot plant for the treatment of HD wastewater was selected and analyzed with the abovementioned parameters. The configuration of the EO reactor in the pilot plant was taken from the studies carried out by Castro et al; [20] the flow rate of this 15 L reactor was 2.6 L • min À 1 , while the flow rate of 2 L • min À 1 in the EC reactor was obtained experimentally in this work with a 2.5 cm inter-electrode distance, considering the arrangement of electrodes for EC of SS-304 j j Ti, and for EO of IrO 2 À Ta 2 O 5 (70 : 30) j Ti j j Ti using grade 2 Ti.…”

“…In addition, the EO reactor was considered to have a flow of 2.4 L • s À 1 ; this flow was obtained in a previous study while treating wastewater containing AMX. [20] The initial data for the model parameters were obtained experimentally at the laboratory level or while characterizing the pilot plant with the synthetic water treatment setting discharge water volume, the TSS, and the VSS being 99 % removed. Several parameters that could not be measured at the laboratory level or the pilot level for synthetic HD water, including BOD 5 and COD, were observed in the simulation.…”

Hemodialysis treatment in specialized clinics within the same hospital significantly impacts environmental water health due to contaminated wastewater. The issues observed included changes in electrical conductivity, the presence of dangerous bacterial loads, toxicity from heavy metals, total cyanide content, and helminth parasite eggs. The level of damage is dependent on the patient’s health under treatment. This research will use a modular system that employs electrocoagulation and electro‐oxidation processes at the laboratory and pilot levels to treat hemodialysis wastewater using synthetically prepared and real samples extracted from local clinics. The results showed that these hybrid systems improved various physicochemical parameters. With these results and the experimental conditions used, the proposed treatment system was modeled using the GPS‐X program, and it was concluded that the modular system used and the electrocoagulation /electro‐oxidation/activated carbon configuration is suitable for treating wastewater from hemodialysis and that scaling up this process to facilities that have dialysate machines more advanced than those considered in this work is possible.
