NC State has a wealth of experience in the bleaching of fibrous furnishes. This experience extends to both ECF and TCF sequences and includes low-, medium-, and high-consistency conditions. Screening and preliminary trials may be done cost-effectively in sealed plastic bags (atmospheric) or small bombs (pressurized). Larger quantities may be bleached using equipment in the pilot plant.
Bleaching agents with which NC State has experiences include the following: chlorine, hypo, chlorine dioxide, oxygen- and peroxide-reinforced extraction, oxygen, peroxide, ozone, peracids, enzymes, and mediated enzyme systems.
