The pigment industry is one of the most important industries in India. Its biggest impact on the environment is related to primary water consumption and wastewater discharge. Reuse of wastewaters represents an economical and ecological challenge for the chemical sector. In this research, a 3000 m3/month traditional WWTP plant has been investigated and also suggested for installation of tertiary treatment for zero water discharge for a sustainable development. The results showed that the average recycling of water per month were about 80%. The cost excluded for the treatment by the means of electrical energy and by other means; but the recycling of water by removal of effluents with tertiary treatment can save the cost of purchase of fresh water. It is also observed that the environmental safety can be achieved by reducing the acidic contaminated waste water flow to the environment.
