Not all odors in ,wastewater, are from H2S, and there is no correlation between H2S and other odors. The total H2S procedure is good up to 18 mg/1, and higher concentrations must be diluted before testing. H2S ,production, can be controlled by up-sewer aeration which reduces US formation and also stabilizes the ,wastewater, in the collection svstem. 14-104

The textile wastewaters (TWWs) are one of the major sources of environmental pollution, due to the presence of various recalcitrant dyes. It is estimated that about 300,000 t of synthetic dyes are discharged in TWWs every year worldwide. Thus, untreated or incompletely treated TWWs cause harm to aquatic and terrestrial life. To avoid the negative impacts associated to the discharge of TWWs ...
