“…The results show that the MCDI pilot under conditions of 1.2 V and flow rate of 10 mL/min in contact with the synthetic sample of sodium chloride with an initial concentration of 1,200 μs/cm at the duration of 180 min decreased to less than 1.27 μs/cm (more than 99% efficiency). However, in contact with domestic wastewater containing TDS of 276.7 mg/L, EC 437 μs/cm (much less than the actual sample in the present study), turbidity 0.27 NTU, hardness 118.2 mg/L, nitrate 57 mg/L (Lee et al 2019). Also, a study conducted by Jiang et al (2019) to remove phosphate from domestic wastewater using a conventional MCDI system showed that only the maximum efficiency of 57% was reached under conditions with voltage of 1.2 V, flow rate of 24 mL/min, and pH ¼ 7.2.…”

“…Therefore, it is not possible to expect the EC and TDS to fall below the desired level. A study was conducted by Lee et al (2019) for desalination of domestic wastewater. The results show that the MCDI pilot under conditions of 1.2 V and flow rate of 10 mL/min in contact with the synthetic sample of sodium chloride with an initial concentration of 1,200 μs/cm at the duration of 180 min decreased to less than 1.27 μs/cm (more than 99% efficiency).…”

Flow-through capacitive deionization (FTCDI) is a traditional improved flow-by CDI cellular structure, used to remove ions from aqueous solutions. In this study, a new FTCDI was designed consisting of mesh electrodes (ME) containing ion-exchange membranes (IEM) and aerogel carbon granules with a specific surface area of 489 m2/g. All analyses and experiments performed showed that the new design can remove nitrate, phosphate, sodium, calcium, and chloride. Under optimal conditions, the new FTCDI system can remove 82.5, 49, 85, and 90% of sodium chloride, calcium chloride, nitrate, and phosphate with a maximum input concentration of 450 mg/L, 450 mg/L, 70 mg/L, and 3 mg/L, respectively. The efficiency of this system was also evaluated for real samples. Findings of the study showed that if the initial amount of turbidity is 12 NTU, total soluble solids (TDS) 1,700 mg/L, total hardness 540 mg/L, phosphate 0.09 mg/L, nitrate 28.8 mg/L, and electrical conductivity (EC) 3,480 μs/cm, the system can remove 25, 23.5, 33.3, 66.6, 54.4, and 39.1%, respectively.

“…Cold atmospheric pressure plasma (CAPP) is relatively widely used in agriculture and food production for the treatment of plants and seeds and also as a more environmentally friendly way for water desalination or decontamination [1][2][3] and for remediation [4,5]. Recent studies about CAPP effects are focused not just on water purification but also on plasma application on plants as a possible ecological solution for increasing food production.…”

Climate change, environmental pollution and pathogen resistance to available chemical agents are part of the problems that the food industry has to face in order to ensure healthy food for people and livestock. One of the promising solutions to these problems is the use of cold atmospheric pressure plasma (CAPP). Plasma is suitable for efficient surface decontamination of seeds and food products, germination enhancement and obtaining higher yields in agricultural production. However, the plasma effects vary due to plasma source, treatment conditions and seed type. In our study, we tried to find the proper conditions for treatment of barley grains by diffuse coplanar surface barrier discharge, in which positive effects of CAPP, such as enhanced germination or decontamination effects, would be maximized and harmful effects, such as oxidation and genotoxic potential, minimized. Besides germination parameters, we evaluated DNA damage and activities of various germination and antioxidant enzymes in barley seedlings. Plasma exposure resulted in changes in germination parameters and enzyme activities. Longer exposures had also genotoxic effects. As such, our findings indicate that appropriate plasma exposure conditions need to be carefully optimized in order to preserve germination, oxidation balance and genome stability, should CAPP be used in agricultural practice.

“…A membrane capacitive deionization (MCDI) stack with 10 pairs of 20 cm × 20 cm activated carbon electrodes was used to desalinate secondary effluent from a domestic WRRF for water reclamation (Lee et al, 2019). The authors showed that MCDI can effectively remove undesired ions such as calcium and nitrate, producing low-salinity water with a conductivity as low as 1.27 µm/cm.…”

Literature published in 2019 pertinent to water reclamation and reuse has been classified into five sections: safe reuse, treatment technologies, management, assessment, and case studies. Membranes have been widely applied in integrated processes to polish secondary effluent and achieve high-quality reclaimed water. Increased efforts have also been made to facilitate feasible and safe water reuse.
