Activated carbon has been used for chloramine removal long before catalytic carbon, a form of activated carbon, became available; standard activated carbon requires a very long contact time, which means a large volume of carbon is needed.
Karbon aktif telah digunakan untuk menghilangkan kloramina jauh sebelum tersedianya karbon katalitik; karbon aktif standar memerlukan waktu kontak yang sangat lama, yang artinya diperlukan karbon yang sangat banyak.
