Abstract
Dyeing bath wastewater in textile industry are mainly characterized by high chemical oxygen demand (COD) and colour. Chemical treatment is one of the common methods applied to such wastewater to reduce the polluting loads prior to biological treatment. This study presents the findings of a series of Jar Test experiments for four different dyeing bath wastewater aiming to put forth the COD and colour removal efficiencies by applying three different chemical coagulants, namely alum, ferrous sulphate and ferric chloride at various dosages. The selection of appropriate chemical coagulants and optimum dosages generally necessitate the conductance of treatability studies in the treatment of textile industry wastewater.
