| Its a mix TG, algae, organics at several levels of degradation, doc's and so on. If you have a larger peice of waste, it rises up the foam colum, but its weight forces it back down, sliding from bubble to bubble and never really getting to the collection cup. Going with a wetter foam increases the speed of the foam rising in the tube, this increases the chances of the larger particles making it to the top. In the dry foam concept you do the same but just further down the tube, but by the time it gets to the top it is dry and all the larger particles have dropped back into the water, what we are doing, is allowing what would normally be dry foam to form in the 5 gallon bucket that all the skimmate goes to??? make sence
