Huang, Wenqing (author)The excessive nitrogen in waterbodies, often caused by the discharge of ammonia-rich wastewaters, leads to eutrophication, disrupting aquatic ecosystems. Wastewater treatment plants play an important role in the removal and recovery of nitrogen from wastewater streams, thereby preventing pollution. Air stripping in combination with acid...master thesis 2024

Thiruvenkatachari, Priyadarshini (author)Elevated levels of ammonia in discharged water leads to eutrophication and potential toxicity in water bodies. To combat nitrogen pollution, strict ammonium discharge limits of 1 mgNH<sub>4</sub>-N/L standard is set by the water framework directory. In many cases, current wastewater treatment facilities struggle to consistently meet this...master thesis 2023

(author)This study reports the effects of microaeration on a laboratory-scale AnMBR (MA-AnMBR) fed with synthetic concentrated domestic sewage. The imposed oxygen load mimics the oxygen load coming from a dissolved air flotation (DAF) unit, establishing an anaerobic digester-DAF (AD-DAF) combination with sludge recycling. Results showed a reduced COD...journal article 2023
