Ｗhy Reactivation
Cost Reduction - Virgin activated carbon is more costly than reactivated carbon
Resources of activated carbon scarce and cost of virgin activated carbon become higher. Through reactivation process, we can ensure spent carbon is returned to a reusable quality and the save more costs for our customers.
Disposal Issues - Consequence of environmental containment
Once activated carbon is fully statured and contains contaminants, disposal would be a problem to the user. Illegal disposal is forbidden and there would be an invisible cost if user place it inside the warehouse.
Recovery of Absorption Capacity - When activated carbon is saturated or unable to absorb
Activated carbon will be saturated or the treatment objective is no longer reached when the pore volume of activated carbon is fully occupied by organics and it is essential to reactivate the activated carbon for recovering absorbability.
Saturation and Reactivation
Saturation
Pores are saturated, non‐absorbable
Reactivation
Pores are able to absorb again
Acro Reactivation Process
Acro Reactivation Process
Spent activated carbon
-
the activated carbon used and collected
Drying
-
temperature around 100 °C - 150 °C
-
part of the adsorbed low-boiling organic matter is desorbed
-
evaporation
Calcinating(Carbonising)
-
temperature around 400 °C - 600 °C
-
part of the adsorbed low-boiling organic matter is desorbed
-
part of the adsorbed organic matter is thermally decomposed and detaching
Reactivating
-
temperature around 850 °C - 1200 °C
-
part of the adsorbed organic matter is carbonised(condensed)the carbon
-
residue in the pores is removed by activation of the steam
Cooling
-
decrease temperature after reactivation
Reactivation of activated carbon
-
reactivating process is complete
Customers use reactivating activated carbon
