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.

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".
Hygienic valves & components
Hygienic valves from GEA form the core component of matrix-piped process plants. Thanks to a pioneering valve concept that sets standards for its flexibility, as well as the latest control and automation functions, our valves offer manufacturers maximum product safety and process reliability. All GEA hygienic valves are designed to be efficient 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.
