The new ‘Waste water post treatment plant’ will treat the discharge from the existing Effluents Treatment Plant (ETP) in a manner that virtually no liquid effluents are discharged from the site. More importantly, the treated water recovered can be used for the production processes and even as boiler feed, which will bridge the gap in availability of water during the summer months.
LANXESS’ Nagda site has a full fledged effluent treatment plant (ETP) and a state-of-the-art sewage treatment plant which treats sewage water from the colonies around and renders it fit for use in the production processes. After a reverse osmosis step, this water is then used as boiler feed water. Taking another initiative towards sustainability, LANXESS decided to study whether there is a possibility to recycle the entire treated waste water.
The development of the waste water treatment process involved several surveys on water composition from different sources as well as additional measures to pre-condition the waste water for the treatment concept. This included trials and pilot runs and subsequently, the company zeroed in on a concept for the waste water post treatment that involves a reverse osmosis process followed by an evaporation step.
This plant has been built with state-of-the-art technology using advanced materials and world class equipment, in co-operation with some of the best known names in the industry.
This implementation of this project has created a new benchmark in the area of environmental protection, and is an example of LANXESS’ ongoing commitment towards sustainable development.
