Operational Experience of ECF Bleaching.
JAPAN TAPPI JOURNAL, 2002 Oxygen bleaching sequence, efficient washing system and reinforced effluent treatment facilities that had been introduced in Hachinohe mill of Mitsubishi Paper Mill since 1988, was allowed to reduce adsorbed organic halogen (AOX) with greatefficiency. However the global environmental demand intensely trends toward more and more reduction of emission or

Aerobic degradation of 2,4,6-TCP content in ECF bleached effluent
Environment International, 2003 Elemental chlorine-free (ECF) bleach effluents from kraft mill are characterised by: a chemical organic demand/biological organic demand (COD/BOD(5)) ratio of 4, chlorophenol content with low chlorine substitution, and toxicity. The effect of increasing the concentration of 2,4,6-trichlorophenol (2,4,6-TCP) content in ECF bleaching sequence effluent on

Ultrafast and Coherent Dynamics in a Solvent Switchable “Pink Box” Perylene Diimide Dimer
Angewandte Chemie, Volume 136, Issue 39, September 23, 2024.Ultrafast coherent multidimensional spectroscopy probes photoinduced dynamics in a covalent perylene diimide (PDI) dimer exhibiting solvent‐controlled on/off excitonic coupling. Excitonic coupling leads to ultrafast excimer formation. The coupling dependent population and vibrationally coherent dynamics in the two cases are measured and discussed in ...

The Experience of ECF Bleaching Plant Operation
JAPAN TAPPI JOURNAL, 2000 Hokuetsu Paper Niigata Mill started up in June 1998 its third coated paper machine (PM8) with a capacity of 240, 000tpy. For the purpose of not having to purchase as much market pulp for this machine and other upgraded machines, the increase of pulp production capacity and the modernization of the plant were planned are carried out before the machine's
