Microbial Impacts of Transitioning to Direct Potable Reuse Water Systems

Kara Nelson - Professor, Civil and Environmental Engineering

Status: Full- no new appr needed     Weekly Hours: 9-11 hrs     Location: On Campus

Direct potable reuse is a form of wastewater reuse where advanced-treated wastewater is introduced directly to the drinking water distribution system. Bench-scale reactors will be used to simulate drinking water distribution system pipes before and during the transition to direct potable reuse conditions. Microbial water quality parameters will...

Nutrient recovery from waste

Kara Nelson - Professor, Civil and Environmental Engineering

Status: Full- no new appr needed     Weekly Hours: 9-11 hrs     Location: On Campus

Recovering nutrients from wastewater can solve two problems: reducing eutrophication by eliminating nutrient discharges to the environment, and producing a local fertilizer that has lower embedded energy than industrial fertilizer. Our research aims to produce fertilizer by concentrating ammonium from wastewater and urine using struvite precipitation (for phosphorus) and ion...

Generating fertilizer from human urine

Kara Nelson - Professor, Civil and Environmental Engineering

Status: Check back for status     Weekly Hours: 6-8 hrs     Location: On Campus

Despite being less than 1% of the total volume of liquid treated in wastewater treatment plants, urine is responsible for over 80% of the nitrogen in a treatment plants' influent stream. Commonly, this influx of nitrogen is only partially treated, leading to the release of excess nitrogen into the environment...
