Thermal regeneration is a high energy process due to the high required temperatures making it both an energetically and commercially expensive process.
2.
Per adsorption-thermal regeneration cycle between 5 15 wt % of the carbon bed is burnt off resulting in a loss of adsorptive capacity.
3.
The filter wool traps large debris and particles, and the activated carbon thermal regeneration at temperatures of 500 900 �C ( 932 1, 652 �F ), electrochemical regeneration, ultrasound, or other industrial processes.
