In time it becomes part of the combined nitrogen of the soil, where it is neutralized, becoming nitrites and nitrates.
His chief work was the measurement of the amount of the combined nitrogen brought down in the rain, and of the amounts of nitric nitrogen washed out from the soil.
A superstructure-based stochastic reaction-separation network optimization methodology has been applied to investigate and optimize the activated sludge process for combined nitrogen and chemical oxygen demand removal.
We designed and developed an ultrahigh-frequency (microwave) plasma torch with a combined (nitrogen, methane) plasma-forming environment, and microwave output of up to 2 kW, continuously.
This results in an example for evaluation of control strategies for combined nitrogen and phosphorus removal from wastewater a necessity in the frame of the SMAC project.
