Designed for high clarification performance and maximum solid thickening, GEA decanters provide reliable dewatering of effluent in municipal sewage treatment plants. The high level of dewatering achieved means that our decanters enable substantially reduced transport and disposal costs. They set standards in terms of dry substance and separation performance, and also require minimal space. Our decanters demonstrate the most efficient use of energy and can enable up to a 50% saving on flocculants compared with other sludge treatment technologies.
GEA decanters effectively demonstrate consistent thickening of effluent. The patented GEA varipond system means that our centrifuges adapt fully automatically to changing feed conditions, to enable consistent dry substance output, even when the solid concentration in the feed varies considerably. Customers benefit from maximum process reliability and unmanned, 24-hour operation, and because of the constant concentration, the digestion tank can be operated more economically: the sludge ferments better and a greater gas yield can be achieved due to the improved quality.
The process of Cambi thermal hydrolysis can also be integrated into municipal sewage treatment plants to allow a significant improvement in anaerobic digestion and thus substantially more efficient dewatering of effluent. Whether for stable pre-dewatering of exactly 16% before hydrolysis, or for dewatering after the digestion process, GEA decanters are the result of decades of experience and comprehensive process technology know-how.
To handle peak loads, our high-performance systems are also available as mobile units. All our plant systems, including all the necessary units, can be installed on containers and thus offer users maximum flexibility.
GEA in addition offers a range of jet and vacuum pumps for conveying liquids such as water, sludge or lyes, solids such as sand, gravel, salt, activated carbon, or ion exchange resin in municipal effluent plants.

The T.VIS® control top is an optimal system for controlling and monitoring GEA valves of the series VARIVENT®, ECOVENT® & T-smart.
The decanter’s hour has come as soon as the solids content in the suspension to be processed is particularly high. These machines provide the benefits of high clarifying efficiency and maximum dewatering as well as the separation of liquids with the simultaneous removal of solids. The main requirements in this respect include a high bowl speed, a...
Dewatering and thickening decanters from GEA are continuously operating horizontal solid bowl centrifuges for efficient sludge treatment and economical volume reduction. The frame is of open design with either gravity or pressure discharge of the clarified phase.
Ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids in which a gaseous or liquid medium serves as the motive force. They are "pumps without moving parts".
