Enhancement of A/O process by hydrocyclone | Atlantis

A modified anoxic/oxic (A/O) process was represented by coupling suspended-growth activated sludge and hydrocyclone, simply termed "AOH" process. The nitrate mixture liquid was firstly transported into hydrocyclone and then returned into the anoxic zone in AOH process. Sludge flocs were disrupted and organic carbon substances including extracellular...

Hydrocyclone - Mineral Processing

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater

Hydrocyclone Separator | Multotec

Hydrocyclone separators are used worldwide in the mining and mineral processing industries for classification, de-sliming and de-watering applications. The main purpose is to separate a stream of particles into different size fractions. However, there are also applications where a fine slime fraction requires removal or where the solids need to be dewatered as much as possible.
