Currently, membrane technologies are restricted in most communities because of water recovery and concentrate disposal limitations. Lower water recoveries mean inefficient use of scarce resources, and concentrate disposal generally requires some form of treatment to meet safe discharge regulations. Injection wells for concentrate disposal are not a...

The Florida Atlantic University faculty and students tested the operating of water plants at higher recovery and gained some preliminary design concepts from student design projects, including meeting Leadership in Energy and Environmental Design (LEED) certification goals. Under the project, the students were not given a budget but were given some threshold criteria such as energy conservation and onsite improvements. It was a found that the off-grid power was difficult to create on the site without significant investments. The final plan proposed to increase the amount of previousness on the site by reducing asphalt and removing unused structures and previous pavements. The design-build procurement process saved the city time in the overall completion of the project and the time from 30% design to final completion took 104 weeks, which is a 74-week reduction in the project schedule.
Because there are few undeveloped or underused high-quality water sources in the United States, many utilities are considering impaired water sources to meet increasing demands. Utilities are increasingly expressing interest in developing aquifer recharge projects and desalination technologies. The evolution of those processes offers significant promise to meet future water supply needs. This project investigated the potential to turn wastewater into a high-quality water supply that meets all applicable state and local standards for groundwater recharge to supplement water supplies. The project showed that membranes can meet virtually every regulatory limit imposed, treating the permeate to resolve saturation issues was straightforward, and emerging constituents were removed efficiently.
