“…To maintain electroneutrality, the electric potential gradient generated by exoelectrogenic bacteria drives cations and anions in the saline solution to migrate through CEM and AEM into the cathode chamber and anode chamber, respectively [81], thereby achieving desalination. The proof-of concept of MDC was firstly proposed by Cao et al [7], and the technology has been advanced through both fundamental research and system development [7,82,83]. Because of the low desalination rate of MDC [84], two potential application niches have been identified.…”

Bioelectrochemical systems (BES) are a newly emerged technology for energy-efficient water and wastewater treatment. Much effort as well as significant progress has been made in advancing this technology towards practical applications treating various types of waste. However, BES application for agriculture has not been well explored. Herein, studies of BES related to agriculture are reviewed and the potential applications of BES for promoting sustainable agriculture are discussed. BES may be applied to treat the waste/wastewater from agricultural production, minimizing contaminants, producing bioenergy, and recovering useful nutrients. BES can also be used to supply irrigation water via desalinating brackish water or producing reclaimed water from wastewater. The energy generated in BES can be used as a power source for wireless sensors monitoring the key parameters for agricultural activities. The importance of BES to sustainable agriculture should be recognized, and future development of this technology should identify proper application niches with technological advancement.

“…Microbial desalination cells (MDC) is a new method of desalination that uses bioelectric potential produced from organic matters via microbial metabolism to accomplish desalination [2]. The efficiency of MDC can be enhance by using stacks of ion exchange membrane between the electrode and by flowing saline water through several MDC.…”

“…Indonesian Republic often crowned as the biggest archipelagic state in the world considering the 17 499 islands, 5,8 million km 2 sea-region area, and a coast line that spread across the country for about 8 000 km [1]. The 5,8 milllion km 2 or approximately 2/3 of the total Indonesian area consists of 2,7 million km 2 area of ZEE (Zona Ekonomi Ekslusif) and 3,1 million km 2 area of territorial sea. From a different source, it is also said that by agreement that has been appointed by UNCLOS in 1982 about 'International Sea Law' (that has been officially ratified in 19 November 1993, signed by 60 UN-member countries, and officially legitimated in 16 November 19\94) Indonesia still has the rights to claim LKRI (Landas Kontinen Republik Indonesia) as far as 350 miles measured from the tip of the territorial line.…”

“…The most common methods of desalination are reverse osmosis (RO), electrodialysis (ED), thermal distillation, freezing, etc [1]. All of these method consume relatively high energy due to the power required for aeration, sludge treatment, high pressure membrane process, and thermal distillation [2]. RO and thermal distillation require (2 to 15) KWh to produce 1m 3 fresh water from sea water [6].…”

Energy crisis issue is appearing. The fact that there will no longer be enough unrenewable energy sources to fulfill global energy demand forces us to come up with some initiatives to overcome this. One way to do it is by trying to conserve energy in any way possible, such as in the production of reliable water sources. Microbial desalination cells (MDC) is one of the methods used in salt water desalination process. It runs on bioelectric potential produced because of the metabolism done by microbes. The results of more recent findings shows that wastewater-based three-chambered MDC offers a new solution to resolve both issues concering energy and water crisis, also with higher efficiency than other common desalination process such as reverse osmosis, electrodialysis, thermal distillation, and freezing. Indonesia's nature as an archipelago country that is surrounded by enormous amount of salt water held the potential of MDC implementation to become a solution of energy crisis caused by the upcoming extinction of fossil fuel.
