Pesticides are mainly includes all of the following:
- herbicides
- insecticides
- fungicides
A pesticide consists of an active ingredient coupled with inert ingredients. The active ingredient kills the pests, while the inert ingredients facilitate spraying and coating the target plant.
Originally active ingredients were once distilled from natural substances and are now often synthesized from petroleum. In addition the contain other ingredients like chlorine, sulfur, phosphorus, nitrogen, and bromine.
Inert ingredients can be many substances, like water, kerosene, emulsifier if the pesticide is a liquid. A powder pesticide will typically contain vegetable matter such as corn cobs, clays or powdered minerals.
During their production a large volume of exhaust is generated and needs to be treated. Generally first dust & particle removal apply followed by physical and chemical absorption process.
These by-products often contain components such as ammonia, phosphate or urea. To remove these components, GEA designs gas scrubbing systems consisting of a combination of dry and wet gas scrubbing stages.

Absorption & Gas Scrubbing
GEA supplies scrubbers for an efficient multi-pollutant cleaning of process-and-exhaust gases for various applications.
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".

The water equation
Across Europe, drought is a recurring reality – and no longer confined to the south. While water increasingly shapes where industries locate, its value is determined by local context. There are many technological routes to water efficiency in industrial processes, but location, energy needs and other factors are also key.
