Extractable, organically bound chlorine (EOCl), which is determined by neutron activation analysis (NAA), has been used as a measure of pollution by chlorinated organics. In this study, the concentrations and distribution of extractable organohalogens (EOX = EOCl + EOBr + EOI) were measured in sediment, blue crab, fishes, birds, and terrapin collected at an estuarine marsh Cited by: Characterization of persistent colors and decolorization of effluent from biologically treated cellulosic ethanol production wastewater.

Additional studies showed that MNPs play a dominant role in the decolorization of chlorolignols in bleached kraft pulp effluents and that LIPs play a relatively minor role in this process.

      Kraft lignin (KL) is the major pollutant in black liquor. The bacterial strain Pandoraea sp. B-6 was able to degrade KL without any co-substrate under high alkaline conditions. At least % of chemical oxygen demand and % of color were removed in 7 days at concentrations from 1 to 6 g L − optimum pH for KL degradation was 10 and the Cited by:

Kraft pulp bleaching effluent supplemented with glucose was decolorized by a newly isolated fungusGeotrichum candidum Dec 1 (Dec 1) that showed a wide decolorizing spectrum to synthetic dyes. When the glucose concentration in the effluent was 30 g/l, the color removal and the reduction of absorbable organic halogens were 78% and 43% after 7 days Cited by: White rot fungi have the ability to degrade hg- nm and lignin derivatives and the utilization of these fungi in biotechnological processes for the decolorization of pulp mill effluents has become a topic of great interest.2~3 Intensive investigations have shown that chlorinated kraft lignin effluents from the extraction stage can be degraded and decolorized by the white rot fungi Phanerochaete chiysosporium and Coriolus versicolor The decolorization Cited by: Decolorization of Kraft effluent by free and immobilized lignin peroxidases and horseradish peroxidase Article (PDF Available) in Biotechnology Letters 13(8).

Electrochemical decolorization of Direct Black dye can be effectively performed in electrochemical techniques to treat effluents containing this dye such that found in textile industry with high percentage of decolorization.

The use of salt in the process relies on the formation hypochlorate which seems to be a good oxidant for this type.

Effluents from the primary clarifier and aerated treatment pond were treated, and the performance of the adsorbent was investigated in terms of decolorization, total organic carbon, and oxygen demand level.

Increasing adsorbent dosage and lower pH resulted in greater adsorption performance. mill effluents (BKME) ranges from negative to 32%, and efficiencies are much less than COD (chemical oxygen demand) removal of 39 to 71% and BOD 7 (biochemi- cal oxygen demand) removal of 81 to Electrochemical oxidation is capable of destroying the chromophore groups of dyes found in textile effluents at short treatment times and low energy consumption.

However, this is accompanied by a moderate degree of mineralization.

In this paper the decolorization and degradation of synthetic and real wastewater by electrochemical oxidation method were investigated.

Synthetic wastewater consisting of Mordant Red 3 (MR3) was used as a model compound. Studies were conducted on the composition of chloro-organics in kraft-pulp bleach plant E-1 effluents and their response toward advanced oxidation processes, such as UV- O 2 /UV- O 3 /UV- and O 3 –H 2 O 2 /UV-photolysis processes with irradiation of nm photons.
