Treated vinasse is originated by a decantation and filtration process. The first, decantation, works best with coarse sediments. A settling chamber where the two phases separate by static decantation. Enzymes are added to facilitate colour separation and decantation. Fat is determined in butter by decantation. The solution can then be separated by filtration or decantation. The oil and vegetation water are then separated by standard decantation. Once the depot is full, remediation will be done by decantation. Decantation is the first step for proper solidification. Plasma can be separated from blood through decantation by using a centrifuge. In laboratory situations, decantation of mixtures containing solids and liquids occur in test tubes. "Decantation" is a form of prosodic reduction. Decantation can be used to separate immiscible liquids that have different densities.
