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.

Research Report - How Engineers are Using Remote Access
Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
eBook - Managing the Context of Product Complexity Using the Digital Twin
Keeping track of changes to complex products is difficult—think Aerospace & Defense equipment, new generations of commercial aircraft, and software-based automobiles. A new way to managing the digital context of the physical product is required and the answer is the Digital Twin. This ebook explores the opportunity available for Operations and Maintenance for the Digital Twin. Download Now
White Paper - Trends in Industrial Filtration
Substantial progress has been made in filtration technologies in recent years. New filter media materials, designs and processes have led to filters that are more efficient, reliable, compact and longer lasting. This white paper will discuss the various trends that are impacting operational responsibilities of MROs today and the resources that are available for staying up-to-date on the latest filtration solutions.
