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.
