Solids Settling

Particles settle within the column system since there is no mechanical agitation to suspend them. As such, each particle will have a specific hindered settling velocity dependent on size, density of the particle and the effective density and viscosity of the suspension with modifications due to bubble-induced mixing. Mixing enhances particle suspension, so small and/or light particles do not have their own trajectory and follow liquid flow more than in two-phase systems. The settling velocity generally has little influence on residence time for particles smaller than about 20 |im, but becomes an important design condition for larger particles.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
