Biological treatment of coke making wastewater.

Raper, Eleanor (2017-04)

Production of coke for steel manufacturing produces a wastewater containing total nitrogen (TN) (up to 600 mg/L) alongside toxic compounds phenol (60 - 400 mg/L), thiocyanate (SCN-) (100 - 400 mg/L), polycyclic aromatic ...
Characterisation of thiocyanate degradation in a mixed culture activated sludge process treating coke wastewater

Raper, Eleanor; Stephenson, Tom; Fisher, Raymond; Anderson, David R.; Soares, Ana (Elsevier, 2019-05-22)

Microbial degradation of thiocyanate (SCN−) has been reported to suffer from instability highlighting the need for improved understanding of underlying mechanisms and boundaries. Respirometry, batch tests and DNA sequencing ...
Enhancing the removal of hazardous pollutants from coke making wastewater by dosing activated carbon to a pilot‐scale activated sludge process

Raper, Eleanor; Soares, Ana; Chen, J.; Sutcliffe, A.; Aries, E.; Anderson, D.; Stephenson, Tom (Wiley: 12 months, 2017-02-09)

Powdered activated carbon (PAC) was investigated for its ability to remove 6 polycyclic aromatic hydrocarbons (Σ6PAHs) (fluoranthene, benzo[b + J]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3-cd]pyrene, ...
Enhancing the removal of pollutants from coke wastewater by bioaugmentation: a scoping study

Raper, Eleanor; Stephenson, Tom; Simões, Francisco; Fisher, Raymond; Anderson, David R.; Soares, Ana (2018-02-09)

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. ...
Industrial wastewater treatment through bioaugmentation

Raper, Eleanor; Stephenson, Tom; Anderson, D. R.; Fisher, R.; Soares, Ana (Elsevier, 2018-06-28)

Bioaugmentation of activated sludge processes through the addition of microorganisms is employed with the aim of enhancing treatment, in particular the removal of priority pollutants. With industrial wastewaters, studies ...
Nitrogen removal from coke making wastewater through a pre-denitrification activated sludge process

Raper, Eleanor; Fisher, R.; Anderson, D. R.; Stephenson, Tom; Soares, Ana (Elsevier, 2019-02-14)

Under the Industrial Emissions Directive (IED), coke production wastewater must be treated to produce an effluent characterised by a total nitrogen (TN) <50 mg/L. An anoxic-aerobic activated sludge pilot-plant (1 m3) fed ...
