Forced ammonia stripping from livestock wastewater: the influence of some physico-chemical parameters of the wastewater
In highly alkaline aqueous solutions (pH >10), the main form of dissolved ammoniacal nitrogen is the unionized free ammonia. Free ammonia, being a gaseous molecule, is easily stripped out from the solution. Increasing wastewater pH is frequently used to force ammonia removal. Herein, the effect of the variation of some physico-chemical characteristics of liquid cattle wastewater on ammonia ...

Air emissions of ammonia and methane from livestock operations: Valuation and policy options
The animal husbandry industry is a major emitter of ammonia (NH3), which is a precursor of fine particulate matter (PM2.5) —arguably, the number-one environment-related public health threat facing the nation. The industry is also a major emitter of methane (CH4), which is an important greenhouse gas (GHG). We present an integrated process model of the engineering economics of technologies to ...
