6.2.2.3. Foam fractionators
Foam fractionators are very useful but sometimes optional pieces of equipment.
-
They are good at removing small particles (under 10 microns) and surface active compounds.
-
They are sometimes referred to as protein skimmers. Since proteins are nitrogenous compounds that degrade into ammonia, foam fractionators can reduce the load on the biofilters.
-
They are definitely useful in systems where water clarity is important.
-
Foam fractionators also add oxygen to the water as a secondary benefit.
-
Unfortunately, foam fractionators do not always work well in fresh water.
