GEA Centrifugal technology
Decanters
Decanters, also called solid-wall scroll centrifuges, operate with a horizontal axis of rotation and are used in waste water treatment for thickening sewage sludge and dewatering. They function on the principle of tube centrifuges but are equipped with a scroll rotating at a slightly different speed than the bowl, enabling them to continuously discharge the separated solids out of the centrifuge bowl. This makes possible a high separation efficiency in a small space.Decanter from GEA Westfalia Separator are robust centrifuges and consequently the long-term, quality response to many issues in the treatment of industrial waste waters. A self-cleaning separator can be installed downstream for polishing the liquid phases.
Separators
Separators are able to handle clarifying as well as separating duties, and are used wherever large volumes of liquids with a relatively low solid content have to be treated. The principle and method of operation are roughly equivalent to those of a washing machine, however they are much more complicated and feature sophisticated modifications which can be adjusted to meet the requirements of the specific areas of application. Separators operate with a vertical rotation axis. The heart of the units are disc stacks that are inclined in relation to the vertical axis of operation and have very narrow gaps. As a result of the interaction between rotation and the disc stack, the solids are separated from the liquid to be purified and, depending on the particular type, are ejected through nozzles or by a sliding valve. Depending on the particular area of application, separators are equipped with a concentrate recycling facility or a washing facility. Separators from GEA Westfalia Separator are designed especially for extremely delicate tasks and produce a clear phase separation, high levels of efficiency and an extremely sharp cut.
