Abstract

The Advanced Water Purification System (AWPS) is designed with multiple treatment units to facilitate potable water reuse of the effluent from the Wastewater Treatment Plant (WWTP) in Palo Alto. The membrane filtration process as well as post treatment conditioning results in a high quality recycled water that has a lower salinity concentration. The membrane filtration process separates the suspended particles such as bacteria, protozoa, and viruses from the WWTP effluent as well as reducing the dissolved solids, salts, smaller organic molecules, and trace contaminants by 90-99%. Then, the air stripping tower removes the excess carbon dioxide increasing the pH from the influent RO permeate. The removal of acidity reduces the likelihood of corrosion occurring in the pipes. The design accounted for the peak flow conditions to prevent any overloading for the pipes and pumps. The design of the vertical turbine pumps took into account total dynamic head (TDH) to overcome friction loss and elevation change as well as the design flows. The AWPS is a vital component to the ever growing need for sustainable water supply solutions for regions facing drought concerns. The design of the AWPS supports indirect potable water reuse while maintaining regulatory compliance and protecting public health.
