“…Conventional biological treatment is difficult mainly due to refractory substances. When high-strength ammonium is involved in CW, COD in the wastewater is not sufficient to complete the removal of ammonium [1][2][3][4][5]. Recently, many bacteria have been known to be capable of heterotrophic nitrification and aerobic denitrification [6][7][8][9][10][11][12][13][14].…”

Alcaligenes faecalis No.4, which is capable of heterotrophic nitrification and aerobic denitrification was used to treat coking wastewater (CW) to remove high-strength of ammonium and phenol. First, the phenol-degrading ability of No.4 was verified and a synthetic medium containing lactate and phenol as carbon sources was subsequently applied to the No.4 culture. Both carbon materials were entirely utilized for the complete consumption of ammonium. Next a coking wastewater containing 400mg/l of phenol and 400mg/l of ammonium-nitrogen was treated by the No.4 culture. Both compounds were completely removed through the addition of 4g/l of lactate. The removal rate of ammonium was 1.1kg-N/m 3 /day which is several hundred-fold higher than that in conventional treatment system.

“…Reported bioaugmentation doses vary significantly from 0.007 to 0.75 g L –1 , and do not appear to correlate to pollutant concentration. Therefore, doses tested in this study were selected to cover a broad range which would be feasible for full‐scale applications . Samples were taken regularly.…”

BACKGROUND Bioaugmentation and biostimulation were investigated for their ability to improve the removal of thiocyanate (SCN–), polycyclic aromatic hydrocarbons (PAHs), phenol and trace metals in coke wastewater. Additionally, the ability of the microorganisms supplemented with the bioaugmentation product to survive in a simulated river water discharge was evaluated. RESULTS A commercially available bioaugmentation product composed mainly of Bacillus sp. was mixed with activated sludge biomass. A dose of 0.5 g L–1 increased the removal of Σ6PAHs (sum of fluoranthene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3‐cd]pyrene and benzo[g,h,i]perylene) by 51% and reduced SCN– below 4 mg L–1 enabling compliance with the EU Industrial Emissions Directive (IED). Biostimulation (supplementing micronutrients and alkalinity) allowed compliance for both SCN– and phenol (<0.5 mg L–1). Bacillus sp. accounted for 4.4% of the microbial population after 25 h (1.5 g L–1 dose) which declined to 0.06% after exposure to river water (24 h). Exposure of the activated sludge biomass to river water resulted in a 98.6% decline in viable cell counts. CONCLUSION In order to comply with the IED, bioaugmentation and biostimulation are recommended for the treatment of coke wastewater to enable an effluent Σ6PAHs of 6.6 µg L–1, 0.3 mg L–1 phenol and 1.2 mg L–1 SCN–. Such techniques are not anticipated to impact on downstream river water quality. © 2018 Society of Chemical Industry

“…Bioaugmentation has been investigated to a considerable extent in the area of bioremediation of contaminated soils, 43, 58–60 but much less for wastewater treatment processes 61. Jianlong et al 62 investigated the removal of the heterocyclic nitrogen‐containing aromatic compound quinoline in an anaerobic‐anoxic‐aerobic lab scale process, with and without the addition of the specialized quinoline‐degrading bacterium Burkholderia pickettii. They observed that, while in the process without bioaugmentation poor quinoline removal was observed, quinoline was almost completely degraded in the bioaugmented process.…”

In the removal of organic xenobiotics from wastewaters, biodegradation is an interesting alternative to conventional physical and chemical processes. Biodegradation in biological wastewater treatment plants has the potential advantages of removing the xenobiotics from the environment, transforming them into nontoxic products such as carbon dioxide and new biomass, and being relatively low in cost. Many xenobiotics have been found to be biodegradable as sole carbon and energy source under aerobic conditions, while under anaerobic conditions many chlorinated hydrocarbons can be biodegraded by reductive dechlorination processes. The main limits of biodegradation processes are the limited time for adaptation to the xenobiotics, the very low xenobiotics concentration in the influent, the competition with abiotic removal mechanisms, the limited availability of external substrates for cometabolism, and the intrinsic nonbiodegradability. Existing biological wastewater treatment processes can be modified by using higher values of the solids retention time, bioaugmentation, addition of readily biodegradable substrates to support cometabolism, and the use of anaerobic‐aerobic processes.
