Eutrophication caused by phosphorus (P) leads to water quality problems in aquatic systems, particularly freshwaters, worldwide. Processing of nutrients in shallow habitats removes P from water naturally and periphyton influences P removal from the water column in flowing waters and wetlands. Periphyton plays several roles in removing P from the water column, including P uptake and deposition, ...

The ElectroCore is a new particulate control technology which is intended to augment the performance of aging or underperforming ESPs. Unlike conventional electrostatic precipitators which collect particles on their surfaces, the ElectroCore acts as a separator thereby allowing it to overcome many of the common reentrainment problems. A pilot-scale Advanced ElectroCore Field Prototype was insta...

The development of gasoline direct injection (GDI) engines has provided a strong alternative to port fuel injection engines as they offer increased power output and better fuel economy and carbon dioxide emissions. However, particulate matter (PM) emission reduction from GDI still remains a challenge that needs to be addressed in order to fulfil the increasingly stricter environmental regulatio...

Vertical profiles of suspended particulate trace metals were measured in the Sargasso Sea near Bermuda and in the California Current, northwest Pacific. Using a new in situ pump, sufficiently large samples of particulate matter (order 10mg) were collected to allow measurement of a suite of trace metals as well as major component elements, using several different leaching techniques on separate ...

heavy metals and dyes are major contributors in contamination of water streams. these contaminants enter into our eco- system, thus posing a significant threat to public health, ecological equilibrium and environment. thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspended particl...
