How it is removed
A reactive impregnation fixes formaldehyde to the carbon surface. Formaldehyde is difficult to capture on virgin carbon because it adopts several molecular forms.
Recommended grades

Specification →SURSORB BLEND
Blended permanganate alumina and pelletized carbon
Specification → The specification that decides it CTC activity and impregnant reactivity
Test against your own duty
Capacity depends on inlet concentration, temperature, humidity, contact time and
competing species. Nothing here is an assurance that a grade will perform in your
service — it is a starting point for a trial.
Trial batches run from 1 to 10 tonnes.
