Some facts about foam.

As I mentioned, foam is a combination of organic and inorganic molecules that are attracted to the surface of water- this surface tension can also be created by rising bubbles or the action created by water pounding the surface, such as a TT, water fall or wet/dry like the bakki. The physical evidence of DOCs and POCs is seen when conditions are right. But changes in water temperature, sunlight, pH and barometric pressure will cause a rise, fall, disappearance and recreation of foam. So even in a foam fractionator, you will notice an ebb and flow to the performance ( foam production)- feeding time and early morning being the most productive periods. Foam can be of a dry consistency or a wet one depending on the above factors and the organic content of the water.
