Several industrial processes result in the formation of a variety of effluents. These effluents are toxic and cannot be discharged due to the negative impact on the environment. Therefore, effluent treatment plants are installed to ensure that the contaminants in process fluids are isolated so that the non-toxic components can be safely discharged. ETP's can involve either biological or chemical processes and in some instances as combination of both. A more recent generation of ETP's are the Zero Liquid Discharge Plants. As the name suggests, these plants only produce a solid waste to be disposed. LEED has experience in treating complex and corrosive effluents rich in chrome and nickel.
