Floatation Pods

Floatation Pods. I have an 18' xpress with a yammy 90 4 stroke. I love everything about the boat except for how damn low it sits in the back. I still can't figure out why xpress put two batteries an 18 gallon fuel tank and close to a 400 lb motor all on the stern of the boat. I've thought about relocating the batteries and I still may.

It helps minerals rise to the surface because the froth is buoyant and helps them rise. Particles and bubbles can only stay in touch when the stable foam is present. A strong connection between the bubble and the mineral makes the froth stay in place or fall apart. An equation called the Young-Dupre Equation would help you figure this out.

Flotation Froth

Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles ( Fig. 17 ). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.
