Regeneration
CECA operates one of Europe’s largest plants for the regeneration of granule activated carbon in LEGNAGO, northern Italy.
Regeneration of granule activated carbon is the most ecological solution to avoid waste after treatment. With increasing landfill costs, it is also becoming the most cost-effective solution for players in the water industry.
Reactivation consists of a high temperature treatment that destroys organic pollutants trapped in the carbon, thereby freeing the pores of the adsorbent. All granule activated carbon grades (crushed or extruded) which are sufficiently hard can be reactivated. This process restores their initial effectiveness.
CECA operates two regeneration rotary kilns. Each is dedicated to regenerating a particular type of activated carbon:
- Activated carbon used in drinking water, the food industry, and vitamin manufacture.
- Activated carbon used in waste water treatment, solvent recovery, and the treatment of air.
The two types of carbon are never regenerated in the same kiln. This enables us to offer a vital guarantee to users of "food-grade" activated carbon.
Shuttle containers
Eager to fulfil our customers’ expectations and anticipate their requirement trends, CECA has set up a shuttle system offering a comprehensive service package to our customers. The shuttle concept eliminates all risks of handling the activated carbon load once it is saturated.
The shuttle system is a cost-effective solution for small volumes, as it uses the spent activated carbon collection centres that CECA has set up as part of this service.
This solution allows CECA to group spent activated carbon loads from several sites into full loads for transport purposes.
The shuttles consist of 50 litre to 30 m3 mobile containers, filled with virgin or reactivated carbon, for delivery.
Both in the treatment of waste gas and in the treatment of liquid effluent, the wide range of filters in terms of activated carbon volume and construction material means that every type of application can be accommodated, and so can flow variations over time resulting from changes to the shuttle’s volume (increase or reduction of volume).
