Innovative Application of MBR, Ozone, and Odor Control Processes for High-Performance Scalping Plants for Water Reuse

Many cities in the United States obtain potable water from multiple sources to maintain diversity in its supply. Groundwater and wholesale imported water supplies are commonly found sources. With ever increasing population and an uncertainty in the long-term sustainability of reliable potable water sources, some cities have decided to investigate water reuse as a means to compliment water supply demand. A Water Reclamation Facility (WRF) that scalps flow from a donor sewer to produce high-quality reuse water can play an important role in offsetting surrounding potable water demands. Often, high-demand users are located in built-up areas when available land is limited and offices and homes are next door. The solution to this problem is to provide a WRF that incorporates advanced treatment processes such as a membrane bioreactor (MBR), ozone and a state-of-the-art odor control system. This paper discusses a typical application of implementing a WRF within a developed city environment.
