In fixed growth systems, microorganisms are attached to a surface that is exposed to the water. We supply numerous systems of this type, including rotating biological contactors, trickling filters, and fixed film bioreactors.

Suspended growth refers to systems where the microorganisms are freely suspended in the water. We offer a full range of suspended growth systems, including activated sludge, sequencing batch reactors, oxidation ditches, and more.
