Activated sludge processes are a great option for treating wastewater. The activated sludge process was first developed in England in 1914 and has remained the most commonly applied biological wastewater treatment process being capable of removing a huge array of pollutants.

Whilst activated sludge processes have been around since 1914 there is still a lot more to be learnt as they are being utilised in the treatment of a greater diversity of wastewater types. Our Senior Geoscientist, Eleanor Raper gained a PhD in the biological treatment of industrial wastewater before starting at Envireau Water and has recently published her final paper on thiocyanate degradation in a mixed culture activated sludge process. Thiocyanate is highly toxic and produced in many industrial processes and as such, needs to be removed effectively from wastewater streams but understanding in thiocyanate degradation has been limited. In her paper, Eleanor identified the bacteria capable of thiocyanate degradation in a mixed culture, explored their degradation capabilities and the conditions required for optimal thiocyanate degradation.

Do your require support for your biological wastewater treatment process? Envireau Water can support you by:

  • Troubleshooting and optimising your activated sludge processes for the treatment of a range of wastewater including both domestic and industrial wastewaters.
  • Providing advice on process monitoring and control for a range of activated sludge processes including biofilm processes such as submerged aerated filters and trickling filters.
  • Supporting pilot-plant systems and development.
  • Supporting water discharge applications.
