Breakpoint Chlorination as an Alternate means for Ammoia-Nitrogen removal at a Water Reclamation Plant
Numerous wastewater treatment processes are currently available for nitrogen removal or ammonia conversion to nitrate. Those that are economically feasible rely mostly on microbiological processes, which are only effective when the microorganisms remain in a healthy state. If a biological process …

Treatability of Dissolved Organic Nitrogen in Truckee Meadows Water Reclamation Facility Using Coagulation or Ozone Treatment
The Truckee Meadows Water Reclamation Facility (TMWRF) has a waste load allocation (WLA) of 500 lbs/day for total nitrogen and a significant portion of the total nitrogen in TMWRF's effluent is comprised of dissolved organic nitrogen (DON). This research addressed the treatability of DON collected …

Advancing Forward Osmosis for Energy-efficient Wastewater Treatment towards Enhanced Water Reuse and Resource Recovery
Current treatment of wastewater can effectively remove the contaminants; however, the effluent is still not widely reused because of some undesired substances like pathogens and trace organic chemicals. To promote water reuse, membrane-based technologies have emerged as a robust and more efficient …
