The coagulated water can either be filtered directly through a medium filter (such as sand and gravel), a microfiltration or ultrafiltration membrane, or it can be moved to a settling tank. In a settling tank, or clarifier, the heavy particles settle to the bottom and are removed, and the water moves on to the filtration step of the treatment ...

Self-cleaning Disc Filter. These particular filters can easily be confused with traditional cartridge filters, as the housings are quite similar. However, the filtration units inside them are very different. As the name implies, the "cartridges" are made of discs. To make disc filter cartridges, polypropylene discs are stacked and pressed together.
