Test organisms

Nematoda: Caenorhabditis elegans (ref. ID; 6821)

[Municipal wastewater treatment plant, USA]

The effluents of all three industries (a yarn dyeing facility (dyehouse), a fiberglass manufacturer, and a pulp processing facility) combine prior to entrance into the WWTP, where this influent subsequently mixes with town sewage waste, undergoes biological treatment.

Test organisms

Nematoda: Caenorhabditis elegans (ref. ID; 7003)

[Tannery effluents]

Test organisms

Oligochaeta: Lampito mauritii (ref. ID; 6008)

[Textile dyeing industries (dyehouses)]

Ozonation of coloured wastewaters from industries involved in dyeing processes is an effective treatment option for effluent decolorization. The decolorization of dyes in wastewaters results from direct and indirect reactions of ozone with the dye molecules. Excess salinity used in the dyeing process to increase fixation or reactive dyes to fibers, as well as heavy metal components of some dye wastewaters. (ref. ID; 7005)
