“…The idea is to remove or destroy the nitrate in waste brine so that it can be recycled and reused for regeneration. Various approaches to biological denitrification of nitratecontaining ion exchange brine have been investigated (Hoek et al, 1988;Clifford and Liu, 1993;Liu and Clifford, 1996;Bae et al, 2002;Okeke et al, 2002;McAdam and Judd, 2008;Sahu et al, 2009). For example, Bae et al (2002) showed that regeneration using recycled brine combined with biological denitrification was nearly as effective as regeneration using fresh 3% NaCl solution ( Table 13).…”

“…The challenge is then effective regeneration using bicarbonate. Both biological denitrification and electrochemical reduction of nitrate-laden bicarbonate regeneration solution have been investigated (Hoek et al, 1988;Matosic et al, 2000;Jelinek et al, 2004;Paidar et al, 2004;McAdam and Judd, 2008). Further research has the potential to improve these processes.…”

“…As for the aforementioned examples, desalination concentrates contain a higher salt concentration than seawater (used as feed for desalination plants) and they are also contaminated with several chemicals utilized during the desalination process. Spent brine regenerant is a brine effluent that comes from ion-exchange processes and is polluted with resins, multivalent ions of softening plants or organic contaminants [6][7][8]. Meanwhile, ballast water is seawater containing wide varieties of microorganisms, which may conflict with the different ecological environments wherein it is discharged [9].…”

Abstract. Brine discharge is one of the largest sources of wastewater from industrial processes. Because of the environmental impacts arising from improper treatment of brine discharge and more rigorous regulations of pollution control, industries have started to focus on waste minimization and improving the process of wastewater treatment. Several approaches have been proposed to provide a strategy for brine handling by recovering both brine and water or to remove pollutant components so it complies with environmental regulations when discharged. One of the most promising alternatives to brine disposal is reusing the brine, which results in reduction of pollution, minimizing waste volume and salt recovery. The brine may also contain valuable components that could be recovered for profitable use. Also, water recovery from brine effluent is generally performed to save water. In the case of rejected brine from desalination plants, water recovery from higher brine concentrations has huge potential for salt production. This paper gives an overview of different types of brine effluents, their sources and characteristics. Also discussed are impacts of brine on the environment and management options related to their characteristics.

“…Denitrification of spent regeneration brine relies on an external carbon source as an electron donor and microorganisms which use nitrate rather than oxygen as an electron acceptor. 1,2 If there is insufficient carbon in the wastewater, an external source is necessary. Various carbon sources in different amounts could be used for denitirfication processes, however, discrepancies have been reported regarding process efficiency.…”

Denitrification of Spent Regenerated Brine Using Molasses

Abstract. Spent BRINE from the regeneration of exhausted resins has to be properly treated before its disposal. The heterotrophic denitrification of regenerated brine was studied in present work. Molasses which served as a carbon source has until now not been applied during brine denitrification. The nitrate and nitrite consumptions were observed according to different ratios between total organic carbon and nitrate (TOC / NO 3 ratios) and the influence of NaCl was studied during batch experiments. This work ascertained that molasses is a very good source of carbon, and no addition of other nutrients is necessary. The complete nitrate removal from regenerated brine could be achieved using molasses.
