Abstract
A foam reducing device may impart a mechanical shear flow to a foam and may dispense an anti-foam agent. The device may reduce highly aerated foam into a dense foam or a liquid, and may significantly reduce the volume of material. One version of the device may have an inlet tube with a nominal diameter or dimension, where the inlet tube transitions to a pair of surfaces that are close together. The foam passes through the pair of surfaces causing flow with a high a mechanical shear. A mesh material may be present between the surfaces, and the mesh material may be treated with an anti-foam agent, such as silicone, which may further reduce the volume of foam. A catch basin may collect the reduced foam for disposal. The pair of surfaces may be configured with a weight or spring to move with respect to each other during periods of high flow.
