Rapid gravity sand filters: Developments in filter floor

An upward flow of water or a combination of air and water to fluidise and scour the media is required. While the proper filter media is important to the performance of rapid gravity filters evidence suggests that filtration and backwashing performance is highly dependent upon the design of the filter underdrain and the support for the filter medium.

Oil and water separation at its best - Twentyfour7

Separation efficiency can usually be influenced by increasing gravity forces density difference and the diameter of the water droplets or by reducing viscosity. Droplet growth caused by the electric fields therefore leads to a substantial growth in the settling velocity of the dispersed droplets and enhances separation efficiency.
