TOC reduction in effluents

TOC reduction in effluents

TOC reduction in effluents

(OP)
I just graduated and have just started work. The second day I got a project to reduce the flow rate and concentration (TOC) of the effluents of the plant (manufacturing lubricants and surfactants). I have no experience in environmental engineering and  have to propose different possibilities or technologies to reduce the flows leaving the plant and TOC levels of the stream. Any suggestions about the possible things to do and how to start?

RE: TOC reduction in effluents

Hi mendietan

I'm not sure to understand exactly what "TOC" means as I'm French and haven't seen this before, but I guess it is something like Total Organic Chemicals?

For those kind of compounds, I know that biofilters / bioscrubbing / trickling biofilters can be efficient, but they don't decrease the flow rate significantly. But there are also non biological treatments

Could you be more accurate on the average level of TOC and flow rate (as those can determine which treatment is the best) ?

RE: TOC reduction in effluents

This sounds like a typical first project for new engineers.  TOC does indeed refer to the concentration of organics in water.  Both aerobic and anerobic digestion (or a combination of the two) are commonly used to reduce TOC.  To reduce th flow rate, you will have to identify the individual contributors to the effluent and convince the owning units to cut back.  Alternatley, you could find a productive use for the effluent, such as irrigation.

White Paper - Considerations for choosing a 3D printing technology
The adoption of 3D printing into major companies’ product development life cycles is a testament to the technology’s incredible benefits to consumers, designers, engineers and manufacturers. While traditional production methods have limitations in manufacturability, 3D printing provides unparalleled design freedom due to the additive method of building parts layer by layer. Download Now
