Application of biochemical oxygen demand (BOD) biosensor for optimization of biological carbon and nitrogen removal from synthetic wastewater in a sequencing batch reactor system

ASSESSING WATER HYACINTH (EICHHORNIA CRASSOPES) AND LETTUCE (PISTIA STRATIOTES)EFFECTIVENESS IN AQUACULTURE WASTEWATER TREATMENT

“…Pistia stratiotes growth was procumbent in nature and at high plant densities, especially within the first two weeks and self shading which resulted in poor utilization of solar energy and decreased microbial activities in the wastewater. Similar observation was reported by Jang et al (2004) in his study on BOD and DO optimization in carbon and nitrogen removal from synthetic wastewater. This may have influenced the DO content in the water and hence responsible for its reduction.…”

Treatment of aquaculture wastewater using ultra-low pressure asymmetric polyethersulfone (PES) membrane

“…In water, ammonium occurs in two forms, which together are called the Total Ammonium Nitrogen (TAN). Chemically, these two forms are represented as NH þ 4 and NH 3 . NH þ 4 is called Ionized Ammonium (IA) because it has a positive electrical charge, and NH 3 is called Unionized Ammonium (UIA) since it is charge less.…”

“…Furthermore, nutrients such as nitrogen and phosphorus are well known to stimulate growth of algae and other photosynthetic aquatic life. These nutrients were also found to lead to excessive eutrophication, excessive loss of oxygen resources, and undesirable changes in aquatic ecosystems [3].…”

“…The results paved the way for the development of the instrumentation for non-invasive characterization of the parameters of sediments in wastewater systems. Jang et al (2003) built a bench scale reactor using a sequencing batch reactor process to evaluate the applicability of biosensors for the process optimization of biological carbon and nitrogen removal. A commercial biochemical oxygen demand (BOD) biosensor with a novel microbial membrane was used to determine the duration of each phase by measuring samples in real time in an SBR cycle with filling/anoxic- Water Environment Federation.…”
