The textile industry is one of the leading sectors in the Tirupur a economy as it contributes nearly 75 percent to the total industrial production can cause untreated inorganic waste water. In this research an attempt is made at finding the efficiencies of powdered natural coagulant alternative to the use of synthetic chemicals to treat the waste water of textile industry. The result obtained by adding Jatropha curcas proved that the plant can be use for the treatment of turbidity in textile industry waste water. The results obtained when the natural coagulant combined with alum were much better. It is found that nearly 96% removal of turbidity is achieved; also complete odor removal is obtained by the coagulation process. Hence Jatropha curcas can be effectively used as a coagulant aid with any chemical coagulant like alum for treatment of waste water from dying industries.
