Cleaner storm water in 45 minutes! (The quick and easy installation of a hydrodynamic separator)

Our first hydrodynamic separator (water quality treatment vault) was installed yesterday in Stamford, CT. This separator will capture trash, sediment, debris and also contain oil.
The TerreKleen is a modular system that installs in about 45 minutes. Here are some pictures showing the installation.















The unit arrived on site via flatbed truck at about 8AM. The crane arrived shortly after. Setting up the crane and final site preparations took about an hour. Around 9AM, the crew started to prepare the unit for installation by attaching these hooks to the TerreKleen. They used these hooks to secure the first section.















The crew wants to get this unit installed as quickly as possible. The installation site is in a tidal area and the tide is starting to come in. The crane operator lifts the TerreKleen off the truck and moves it toward the hole where it is getting installed. The ropes will assist in guiding the unit.

















The working part of the TerreKleen is successfully installed. As you can see, the TerreKl
een is a two chamber system.
The first chamber (near side) is designed to capture: sediment, trash, debris and will
contain oil.
The second chamber (far side) houses the stacked inclined plates. Stacked incline
d plates have been widely used in the potable drinking water industry for the past 80 years. Their use give the TerreKleen the largest sedimentation surface area in the smallest area footprint. Once sediment is captured in the second chamber, they will not re-suspend regardless of flow rate.



















In a few minutes, the riser is installed and we can move on to the final piece.















A few more minutes and the top is positioned for installation.














45 minutes later.....TerreKleen hydrodynamic separator installation is complete! All that is left now is to hook up the pipes and back fill around the unit.

More projects are planned. We will keep you posted.
