pretreatment of a dyeing wastewater using chemical coagulants

Pretreatment of a dyeing wastewater using chemical coagulants

For pretreatment of the feed water of membrane processes, chemical coagulants such as HOC-100A, alum, and ferric chloride were used. The feed water used in this experiment was a synthetic dyeing wastewater composed of Direct Red 75, polyvinyl alcohol (PVA), NaCl and Na 2 SO 4. Total concentration of the materials in the feed water was 2500 ppm.
