Liquid manure from the agricultural sector represents a valuable natural fertilizer. However, liquid manure and the excess nutrients that it may contain must be treated prior to application to fields, to protect the environment and water courses in compliance with stringent legal requirements. GEA can supply both evaporator and decanter technology to tackle any liquid manure treatment application.
GEA manure Decanters efficiently reduce phosphate and nitrogen levels in liquid manure by separating up to 90% of phosphate and 35% of nitrogen compounds along with solids, protecting both groundwater and surface water. The separated, pourable solids are ideal for composting and can be repurposed as fertilizer. The remaining liquid phase is easy to store in a silo and can be applied as a high-quality, eco-friendly natural fertilizer when needed. For maximum flexibility, mobile decanters are also available.
GEA’s evaporator technology is ideally suited to concentrating liquid manure to reduce volume, especially on breeding farms that have very large numbers of animals. Using our evaporators, the liquid manure is concentrated to up to 30% dry solids, and this can then be dried fully in a dryer.
GEA’s evaporator and dryer technologies can both be operated entirely using waste thermal energy.
GEA further supplies equipment like jet and vacuum pumps for conveying water and manure.

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".
