Turn waste stream to process water stream
Condensate from evaporation plants is used as process, cooling, and rinsing water or is directly discharged into a drainage ditch.
For this purpose, the condensate must be purified. Impurities in the condensate can be removed by membrane filtration, in the particular case by reverse osmosis, and high condensate qualities can be achieved.
Condensate from evaporation processes contains impurities such as chemical oxygen demands (COD), ions and other unwanted components. For re-use as process water, these impurities need to be removed. Using reverse osmosis, it is possible to produce a high-grade process water for re-use in the production facility with a low content of ions and a low conductivity level.
The operating pressure and process design depends on the quality of the condensate and the level of purification required.
If the capacity of the system increases, requiring higher volumes of condensate to be treated by a waste water system, the hydraulic load to the waste water system can be reduced up to factor five when installing the Condensate Polisher. The filtrate can be discharged directly if the purity requirements are met.
GEA custom designs membrane filtration systems that best utilize the technologies of microfiltration, ultrafiltration, nanofiltration, or reverse osmosis for each customer's specific application.
GEA cross-flow filtration with robust ceramic membranes are used for the effective recovery of beer from tank bottoms. Modular plants are supplied on compact skids in three standard sizes with processing capacities of approximately 250 hl, 500 hl and 1000 hl per day depending on the dry solids content of the product.
Supporting small to large feed rates, and configurable for both batch and continuous processes, the dedicated AromaPlus system is built on our reverse osmosis (RO) membrane filtration technology.
GEA’s cross-flow membrane filtration units have been specifically designed to deliver a clear, colorless, tasteless and aroma-free neutral alcoholic base. The neutral alcohol base used in a hard seltzer derives from a fermentation process with no distillation step.
While the initial interest in heat pumps was to save on operating costs, reducing emissions is now the main driver for the technology. Learn more about how GEA is spearheading efforts to increase energy efficiency and reduce CO2 emissions through hidden champion heat pump technology for industrial and district heating sectors.
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
