Whether in the food and beverage industry, in refinery applications or in the steel and paper industry, high water consumption is typical of many different process stages in modern industrial production. The effluent volume incurred is also accordingly high, being sometimes contaminated with organic or inorganic, dissolved and undissolved substances or even substances that are harmful to health. The requirements of the relevant treatment technologies are as broad as the variations can be in contamination of the different effluent flows.
GEA decanters not only meet the highest demands for process reliability, hygiene and environmental protection: they are used successfully worldwide for the treatment of industrial effluents, ensuring optimal process results with the greatest possible cost efficiency and minimal use of resources. In the continuous process, they reliably separate out undesired solids, dewater them to a pourable consistency and ensure a high content of dry matter in the separated solid thanks to high separating efficiency. Whilst the clarified centrate can often be returned to the production cycle, the dewatered solids can generally be profitably recycled with further recovery of reusable substances or its volume can be reduced and it can therefore be disposed of cost-effectively.
As well as decanters, GEA also supplies complete industrial sludge dewatering plants with the associated peripherals for flexible use. All the essential process stages are condensed into one entity here with the relevant units in a lorry, trailer or – for even greater flexibility – container. The plants are complete with pipework, automated and ready for use immediately.
As an environmentally compatible solution to effluent treatment, we additionally supply highly efficient evaporation technology with which industrial wastewater can be concentrated reliably into a high-level dry substance. The evaporated water is condensed and can be reused as process water. GEA evaporation plants are operated entirely with the use of heat from peripheral systems and therefore work extremely energy efficiently and are exemplary for the responsible use of valuable resources.

CO2 savings come from reducing fossil fuel demand either by increasing energy efficiency or by separating CO2 from flue gas streams along with long-term fixation in valuable products or storage. GEA offers products and processes for all relevant stages.
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.
