TerreKleen Hydrodynamic Separator (water quality treatment vault) Inspection

Wow - what a great week!  We had our first post installation inspection of the TerreKleen hydrodynamic separators that we installed in Stamford back in November.  I thought these pictures quickly and easily tell the whole story:

The first picture shows the trash that is contained in the TerreKleen.  This trash will be trapped here until these units are maintained/cleaned out.

With trash and debris trapped in the primary chamber of the TerreKleen, this second picture shows the "working" section of the unit.  Stormwater  travels through a screen and onto
the stacked inclined plates (you can see the plates on the right side of the picture).  These plates help smaller sediments fall out.

The TerreKleen design is based on solid engineering principals developed by Allen Hazen in 1905.  This technology was developed to separate sediments from water in the drinking water industry.  The effectiveness of stacked inclined plates (Lamella plates) is well known and recognized as more than 100 years later, this technology is still widely used for sediment separation in the drinking water industry.  The TerreKleen has simply adapted this technology to efficiently separate sediments from storm water runoff.

Here is brief information about Allen Hazen , his education at MIT, his career, contributions and impact on the water industry.  Here is a link to some of his published works.

Another benefit to this client? TerreKleen maintenance / cleanout will NOT require confined space entry!

It feels good to know that this trash has been prevented from littering Long Island Sound this summer.

If you have questions about the TerreKleen, hydrodynamic separation, particle size distribution, trash control or stacked inclined (Lamella) plates, feel free to give us a call!
