Wastewater characteristics oxygen, dissolved

TABLE 6.5. Characteristic Values of COD Components and Dissolved Oxygen at an Upstream Location of an Intercepting Sewer (cf. Figure 3.10). Wastewater Includes Particulate (X) and Soluble (S) Fractions. 

According to Epolito et al. [19] under typical dyeing conditions, up to 50% of the initial dye concentration remains in the spent dye bath in its hydrolyzed form. Thus after dyeing wastewaters are characterized not only by intensive and difficult colour removal but also by high pH, suspended and dissolved solids, chemical and biochemical oxygen demands. Typical characteristics of raw textile wastewaters are presented in Table 4 [12-14, 20, 21].
