This bagfilter technology has been optimized for large volume flows and requires minimal pulse-air equipment. A reduced number of individual parts, high gas-cleaning efficiency, and a compact plant footprint help streamline capital investment for the ECOpuls filter solution.
Thanks to GEA’s low-pressure technology, the air used for bag cleaning is compressed to only 0.8 bar (g). This low compression rate is achieved using energy-efficient rotary lobe blowers instead of conventional high- or medium-pressure systems, which typically incur higher energy consumption. The low overall pressure drop of the ECOpuls filter and extended filter bag lifetime further reduce ongoing operational costs.
The bagfilter can be configured with multiple compartments to enable on-line maintenance. The ECOpuls filter is also suited for integration with other emission control tasks, such as the separation of SO2, mercury, and NOx. Changes in upstream processes or lower clean gas dust loads often prompt a transition from dry electrostatic precipitators (ESPs) to bagfilters, and GEA provides specialized retrofitting services to install these components directly into existing ESP casings.

Working Principle
Working Principle of Bagfilter (ECOpuls)When dust-laden gases flow through a porous layer of fabric or felt, the dust is separated from the carrier gas and deposited on the filter medium. It is re-moved periodically and falls into the dust hopper.
The filter materials used are woven or non-woven fabrics made from natural or man-made fibers as well as inorganic fibers (glass, mineral or metal fibers). A detailed description of the working principle can be watched here:

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.
