The magnificent John G. Shedd Aquarium in Chicago is home to the original denitrification system installed by EcoMat employees. In January of 1998 we installed a second unit, smaller than the first and shipped on its own skid mounting. This equipment is now operating well.

It is a two-hundred liter reactor system, with a foam fractionator. It takes water from several different fish tanks, denitrifying it and returning it to those tanks.
