Publication number: 20240091738Abstract: A synergistic composition can be used to treat water containing nitrogen compounds and phosphorus compounds. The synergistic composition includes iron filings, clay particles, aluminum particles, and sand particles. The iron filings, clay particles, and aluminum particles act synergistically to remove nitrogen compounds and phosphorus compounds from water. Specifically, the clay particles attract the nitrogen compounds and the phosphorus compounds to be absorbed onto a surface of the iron filings and the clay particles. The aluminum particles react with the nitrogen compounds via an oxidation reaction to form ammonia compounds, and react with the phosphorus compounds to produce aluminum phosphate. As such, the synergistic relationship between the iron filings, clay particles, and aluminum particles remove nitrogen and phosphorus compounds from water and recover the compounds in usable forms, namely, ammonia and aluminum phosphate.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Ni-Bin Chang, Debra Reinhart, A H M Anwar Sadmani

Patent number: 10612952Abstract: An Automatic Pulse Tracer Velocimeter (APTV) including arc-type APTVs and cross-type APTVs along with a field station and a master station capable of wireless communication with a remote computing devices. The APTV measures flow velocity in a flowable medium by injecting a small amount of a conductive tracer solution into a water column. Following injection, a plurality of wire detector pairs positioned downstream of the injection point are programmed to continuously make conductivity measurements at pre-determined time intervals. A tracer curve of the conductivity measurements over time is created and used to obtain velocity measurements.Type: GrantFiled: August 18, 2015Date of Patent: April 7, 2020Assignee: University of Central Florida Research Foundation, inc.Inventors: A.
