Agricultural biomass
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 decanters can be used to reduce phosphate and nitrogen fractions efficiently from liquid manure, by separating off up to 90% of phosphate compounds and up to 35% of nitrogen compounds, together with the solids. This protects both groundwater and surface water. The pourable solids can then be composted and used as fertilizer. The liquid phase is suitable for transportation to a silo for storage, and can be applied as a high-quality, environmentally friendly natural fertilizer as required. Mobile decanters are available for optimum flexibility.
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".
