Reducing costs and minimizing pollutants with decanters from GEA
This demonstrates the tremendous advantages of a GEA decanter, both in terms of competitive advantages by way of reducing costs in the paper industry and also for environmental protection by minimizing pollutants.
In addition to the above-mentioned constituents, further chemical substances are also added depending on the desired paper quality – for instance whiteners, inks or dust-inhibiting agents – which have to be removed from the waste water at the end of the production process.
Chemical substances can be reused
During pre-clarification and post-clarification, primary, secondary and flotation sludges are produced which are dewatered individually or together by the decanter. Because of the high dry substance, the storage and disposal costs are reduced, the volume of fresh water is minimized, and expensive chemical substances can be reused on several occasions – a factor which likewise has a positive impact on the economic balance. The dewatered sludge can either be dumped, dried or incinerated.
GEA further supplies equipment like jet and vacuum pumps for conveying liquids such as water or sludge and solids like fibers in the paper industry.

Ancillary Equipment
Ancillary equipment for centrifuges contributes to more sustainable production by making utilities reusable, saving energy and increasing the overall process efficiency.
Decanter Centrifuge
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...
Jet pumps
Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids and for the production of vacuum in which a gaseous or liquid medium serves as the motive force.

Innovating for impact: shaping better solutions for customers
Industrial production is being asked to use fewer resources, become smarter and keep equipment productive for longer. At GEA, that is changing how innovation happens: engineering, customer insight, digital expertise and service come together earlier – when a solution can still be shaped at its core.
