Abstract:

The aim of the present work is to test the ability of the steel industry wastewater (SIWW) iron rich as an original coagulant to remove the textile dyes from wastewaters of textile industry. The SIWW was used in the treatment of four textile dye solutions, namely orange HER, red F2B, blue SRN, and as well as their mixture.

Jar-test experiments were employed in order to determine the optimum conditions for the removal of organic and colored matters. The results showed that: SIWW is effective in the removal of COD and color, it is efficient at a wide pH range, and produced a less volume of decanted sludge compared to classical coagulant FeCl3.

Keywords:

textile dyes wastewater, steel industry wastewater (SIWW), coagulation-flocculation, valorization, jar-test.
