Wastewater, pH measurements were 6 at four of the industrial sites, 5.5 at one site, and 10 at the remaining site. ,Wastewater, sulfide ranged from 0.0 to 0.3 mg/1. The ,wastewater, sulfide level was 0.05 mg/1 at the site where ,wastewater, pH was 5.5, and 0.0 mg/1 at the site where ,wastewater, pH was 10.

Abstract: The effluent from ,biochemical, treatment of pulp and ,paper making wastewater, treated by heterogeneous Fenton fluid-bed reactor was evaluated. The results showed that in the condition of COD 350mg/L, and the optimum conditions of pH at 3, FeSO 4 2.5mmol/L, H 2 O 2 3.4mmol/L, and reaction time at 20 minutes, the removal efficiencies of COD and color are more than 85% and 90%, respectively.

Because hypoiodous ,acid,'s pKa (in freshwater) is 10.4, it is largely in the protonated (uncharged form) in seawater. 3 The hypoiodous ,acid, is itself a strong oxidizer and can go on to react with other organic or inorganic materials. 4 It has also been suggested that very low levels of molecular iodine (I2) may be generated in this way in a thin layer on the ocean's surface (0.0002 ppm, or 0.3% ...
