Electricity generation, salinity, COD removal and anodic biofilm microbial community vary with different anode CODs in a microbial desalination cell for high-salinity mustard tuber wastewater treatment

Abstract

A three-chamber microbial desalination cell (MDC) was constructed for high-salinity mustard tuber wastewater (MTWW) treatment.

Microbial Desalination Cell for Sustainable Water Treatment: A Critical Review

“…It is worth noting that the COD of the anolyte solution is an important parameter in desalination by MDCs. In a study [ 21 ] with domestic sewage as the anolyte solution with COD concentrations of 400, 900, and 1400 mg L −1 , high‐salinity mustard tuber wastewater (MTWW) as desalination stream, and ultrapure water as the catholyte, the COD value of 900 mg L −1 generated more electricity. However, the highest desalination efficiency was obtained at 5.3 mg h −1 at a COD value of 400 mg L −1 .…”

“…--Salt, sulfate, and nitrogen removal using a biocathode MDC. [21] -High-salinity mustard tuber wastewater.…”

“…As can be seen here, MDCs have the flexibility to be used for various kinds of saline solutions such as brine produced by a desalination plant, diluted industrial wastewater, real geothermal water, and seawater. [ 17 , 18 , 19 , 20 ] They produce acceptable treatment results with a desalination performance of up to 97.4% [ 21 ] and a COD removal efficiency of up to 97.8%. [ 20 ] Moreover, they can remove toxic elements such as arsenic [ 17 ] and boron [ 22 ] from water.…”

Harnessing exoelectrogens in a novel microbial desalination cell: a study on the impact of salinity on sago effluent treatment and power generation

“…16 Wastewater also plays an essential role in determining the efficiency of a MDC. 17 Sago effluent, a wastewater released from the sago industries, is rich in organic content and will be a suitable substrate for power generation in MDC. Another important reason for choosing sago effluent in this study is that the high organic content in the effluent released from the industries causes eutrophication and contaminates water bodies.…”

Feasibility of 60Co-γ Irradiation for Sterilization and Hypersaline Wastewater Reduction in Pickled Mustard Tuber Production

“…Consequences include crop death, water contamination, and soil infertility. 3 To mitigate salt levels during pickled mustard tuber production, physicochemical processes like reverse osmosis, ion exchange, evaporation, etc. were directly used or integrated with biological processes such as aerobic/ anaerobic process, cyclic activated sludge system (CASS), and membrane bioreactor reactor (MBR) for pickled mustard tuber wastewater treatment.…”
