A mesoporous carbon for decolourisation and the removal of larger colour bodies, typically in food, beverage and pharmaceutical refining.
Phosphoric-acid and physical routes both produce a low-density, low-pH carbon that performs well in caramel and molasses decolourisation.

Faq
Explore faq details to support your evaluation.
Can wood-based activated carbon be mixed with another carbon in one bed?
Yes, but when loading in layers keep the particle sizes close to avoid channelling, and record the test data for each layer.
What is the minimum order quantity?
One tonne for normal orders; samples of 1-5 kg can be shipped with freight paid by the customer.
What lead time should we expect?
Around 15 days for regular grades, and 3-5 days for stock items.
