“…Saline and hypersaline wastewater (above 3 % salinity) accounts for about 5 % worldwide effluent, generated by extensive industries or practices such as fish aquaculture, food factory, tannery, chemicals, pharmaceuticals, and flushing toilets by seawater (Cui et al 2009;Lefebvre 2006). The wastewater contains high concentration of carbonaceous and nitrogenous contaminants as well as high amount of inorganic salts.…”

Nitrogen removal from hypersaline wastewater was successfully started up by inoculating estuarine sediments for 140 days. Efficient ammonia and total nitrogen removal was sustained under specific ammonia loading of 0.016-0.139 kg N/[kg VSS day] in a sequencing batch reactor. Stable nitrite accumulation was observed during nitrification. The specific ammonia consumption rate was higher than the value of freshwater activated sludge and saltacclimated freshwater activated sludge. With methanol as carbon source, specific nitrite reduction rate of halophilic denitrifiers was much less than the freshwater counterpart. Halophilic activated sludge was characterized as good settling and flocculation prosperity with small floc size and netlike sludge structure. The abundance of ammonia-oxidizing bacteria outnumbered ammonia-oxidizing archaeas in both estuarine sediments and the activated sludge. Nitrifier population was dominated by the halophilic members of genus Nitrosomonas. This study demonstrated the application of mixed halophilic consortia for efficient nitrogen removal, overcoming the limits and difficulties of applying freshwater bacteria for saline wastewater treatment.

“…Low salt concentrations can stimulate microbial growth, but high concentrations (≥10 gl -1 ) are known to inhibit anaerobic systems through an increase of osmotic pressure or dehydration of methanogenic micro-organisms (Hierholtzer and Akunna 2012;Lefebvre and Moletta 2006). The toxicity of salt is predominantly determined by the sodium cation though other light metal ions, such as potassium, have also been found to be toxic to methanogens at high concentrations (Chen et al 2008).…”

“…Mesophilic methanogenic activity is halved at 14 Na g l -1 (Chen et al 2003;Ramakrishnan et al 1998), the approximate concentration of sodium found in sea water (El-Dessouky and Ettouney 2002). Anaerobic digesters can be acclimatised to higher salt levels if they are continuously exposed to gradually increasing salt concentration rather than salt shock (Lefebvre and Moletta 2006). Adaptation of methanogens to high concentrations of sodium over prolonged periods of time can allow the anaerobic digestion of high salt concentration wet biomass with the sodium concentration to halve methanogenic activity increasing to 37.4 g Na l -1 after acclimation (Chen et al 2003).…”

Synthesis and Optimisation of A Sustainable Wastewater Treatment Plant via Material Flow Cost Account (MFCA)-based Approach

Abstract. In this work, MFCA-based approach has been developed to synthesise an optimum wastewater treatment plant (WWTP). To develop the approach, a series of mathematical equations have been generated based on a generic superstructure that presented all possible pathways of WWTP. In this work, four continuous treatment stages (pre-treatment, chemical treatment, biological treatment and tertiary treatment) with various treatment technologies have been considered. In addition, raw material cost, energy cost, labour cost, and waste management cost as well as the hidden cost and carry-forward cost have also been considered in this approach. In this work, hidden cost is referred to the cost that associated with the process stream, while the carry-forward cost is referred to the cost that is carried forward from one process to another process. Furthermore, pollutants (e.g., TSS, COD, BOD and O&G) have also been considered to ensure the discharged water is complied with discharged regulations. To illustrate the developed approach, an industrial case study, has been solved. As results, an optimum sago wastewater treatment process with minimum waste generation cost is synthesised via a commercial optimisation software, LINGO.
