Mitochondria are organelles found in nearly all eukaryotes. They are the powerbank or powerhouse of the cell as they provide energy to the cell by converting ingested sugars into ATP. They are surrounded by two membranes (each a phospholipid bi-layer), the inner .
Dissolved air flotation is an alternative clarification process ideal for treating raw water with light particles, such as algae or color-causing organics, and at low temperatures when .
Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the .
Stabilization of foam is caused by van der Waals forces between the molecules in the foam, electrical double layers created by dipolar surfactants, and the Marangoni effect, which acts as a restoring force to the lamellae. The Marangoni effect is dependent on the .
