Application of light-weight filtration media in an anoxic biofilter for nitrate removal from micro-polluted surface water
The research investigated nitrate removal from micro-polluted surface water by the single-stage process of anoxic biofilter using light-weight polystyrene beads as filtration media. In this study, sodium acetate was used as an external carbon source and the nitrate removal efficiency under different regimes of hydraulic loading rate (HLR), water temperature, and C/N ratio was studied. In ...

Biological treatment of ammonium perchlorate-contaminated wastewater: a review
Absolute reduction of perchlorate has proven complex owing to the diverse characteristics of the perchlorate ion. Technologies such as chemical reduction, ozone/peroxide, nanofiltration, and reverse osmosis have had limited success, high costs and are not environmentally friendly. A great deal of research and reviews on ion exchange and biodegradation have been carried out, but conditions for ...

Study Quantifies Drinking Water Nitrate’s Role in U.S. Cancer Cases
Negative health outcomes from nitrate in drinking water hit farming communities particularly hard A new Environmental Working Group (EWG) study, published inEnvironmental Research, has estimated that nitrate contamination of drinking water will cause thousands of cancer cases annually in the United States. The cancers are also expected to run up $1.5 billion in medical bills each year, with ...

Nitrate Biosensor - Case Study
BACKGROUND In 1998, Dr. Bill Campbell and his team published a peer-reviewed journal article in Analytical Chemistry on the construction and characterization of Nitrate Reductase-Based Amperometric Electrode and Nitrate Assay of Fertilizers and Drinking Water. This publication set the stage for the nitrate biosensor project. In this publication, we found that nitrate reductase was indeed capable ...

Nitrate Pollution Affects Millions in U.S.
According to new study, the water contamination disproportionately affects poor and Hispanic Americans Runoff of agricultural fertilizer is a major source of nitrate pollution in drinking water. A new study in the journal Environmental Justice has determined that 5.6 million Americans served by community water systems (CWSs) in the United States are exposed to excessive nitrate levels in ...
