Multicomponent continuous flow kinetic analysis
An instrumentation system for Multicomponent Continuous Flow Kinetic Analysis has been designed and constructed. Evaluation of the system shows that it is useful for performing dilutions, flow injection analysis and continuous flow kinetics with relative standard deviations of less than 10 percent. …

Evaluation of Continuous Flow Constructed Wetlands Treating Swine Waste
The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating …
