Moving Toward Sustainable Wastewater Treatment

Chemical process applications produce waste, some of which may contain potentially hazardous materials that must be safely removed before liquid effluent is discharged into the environment. Wastewater Treatment (WWT) is closely regulated by stringent government standards and is essential for sustainable chemical processes. Indeed, industry leaders regard sustainability as a social responsibility, preventing pollution and re-using water as one of our most precious resources.

The goal in such environmental initiatives is to extract waste materials as efficiently as possible by maximizing throughput rates using the least amount of energy. With this in mind, engineers at Dow Chemical, based in the united States, embarked on a few projects to study the use of fluid dynamics simulation in designing and operating WWT systems in chemical processing plants. This represents a huge step forward in an industry that has traditionally relied on replicating past designs in new plants.

As the Dow R&D team demonstrated in this project, simulation provides important insight into critical WWT operations and enables engineers to readily explore alternate configurations to quickly and easily arrive at an optimized design. The simulation method created is intended to serve as a foundation in developing designs for new chemical processing plants as well as in troubleshooting existing designs and retrofitting older plants with upgraded WWT systems.
