Industrial effluent
Zero liquid discharge
A global environmental awareness and focus on conserving water and water pollution has led to increasingly stringent regulations on the use and discharge of industrial water. GEA’s zero liquid discharge (ZLD) technology is ideally placed to enable many sectors of industry to clean and recycle their process water, and recover valuable chemicals and compounds.
Recovering marketable by products with ZLD systems
ZLD systems are designed to remove dissolved solids from wastewater and return distilled water back to the process. GEA’s ZLD technologies allow industrial processes to conform with environmental regulations, and are specially designed to capture valuable salts from waste streams before disposal, to generate value-added revenues.
Different technologies are commonly combined to achieve full ZLD. These might include ultrafiltration, reverse osmosis, centrifugal separation, evaporation, crystallization, salting out and drying. GEA can provide a complete portfolio of technologies for recovering valuable by products that can be commercialized.
We have custom-designed and supplied numerous ZLD treatment systems, for example, for coal-fired power plants and waste incinerators. These systems effect heavy metals precipitation, evaporation with seeding (as an anti-scaling measure) and crystallization. We also have many years of experience in the handling of corrosive materials, which means that we can tailor the design and construction of each plant in corrosion-resistant materials, as required.

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...
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...
Ejector Systems
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".

Blueprint for better: How GEA rebuilt itself
Since 2019, GEA has risen from underperformer to DAX member – one of Germany's top 40 listed companies – by fostering entrepreneurship and turning sustainability into a competitive advantage. It reached this milestone in its nearly 145-year history without tailwinds or shortcuts, in a world of compounding crises. This turnaround shows what's possible when purpose and performance align.
