Simplified microbiological treatment of complex wastewater

The diversity of process waters within the chemical and pharmaceutical industries is enormous.

Typical characteristics for wastewaters from this sector are:

  • High organic content, some of which is easy to degrade, typically solvents like alcohols, glycols, etc.
  • Large variations in flow and composition of wastewater due to periodical production
  • May contain toxic and persistent substances
  • Sometimes high content of nitrogen and/or phosphorus
      

Treatment processes include:

 

Typically, wastewater from the chemical or pharmaceutical industry contains easily degradable and more resistant organic matter. Water composition can vary from day to day. 

A biofilm process has many advantages compared to more sensitive process solutions such as an activated sludge process. A multi-step MBBR-process enables the development of unique micro flora in the different process steps. 

By dividing the process into two or more steps it can be optimized for the removal of easily degradable and more hard-to-degrade organic matter.

Effluent discharge limits for treated water vary due to local authorities, customers, and sensitivity of the local environment. 

The main treatment requirement is often COD-removal. Sometimes it is necessary to remove nutrients or reach a certain level of toxicity-removal before discharge. 

Achieving the desired level of nutrient removal can sometimes be a challenge due to the toxic nature of some wastewater. 

The diversity of wastewater and effluent water quality requires customized treatment solutions. 

We recommend testing wastewater in bench or pilot-scale trials.

AnoxKaldnes has worked with the development of optimized treatment solutions for the chemical and pharmaceutical industry for the past twenty years. Our latest development is the Z-Carrier that enables the selection of specialized biomass in dependency of Biofilm thickness. 

Our Biological wastewater treatment solutions are designed to meet your specific needs.
