ata et al. carried out studies on optimization of ammonia removal microwave-assisted air stripping and founded that the optimum conditions were at 1800 mgl of initial concentrations, 7.5 l min 1 of airflow rate, 60 c of temperature, 500 rpm of stirring speed, and 200 w,in liquids we set the measure,sensotech is the provider of systems for the analysis and optimization of processes with liquids. since the establishment in 1990, sensotech has developed into a leading supplier of process analyzers for inline measurement of the concentration and density of liquids. the analytical measuring systems set benchmarks that are used globally.
aug 06, 2015 if this air column collapses, the velocity of the spiral will decrease far enough to lose the centrifugal force that causes the ore to classify. as the internal pressure of the cyclone represents the volume of slurry that is in the cyclone it only follows that the reason that the air column should collapse is that there isnt room left in the,m113 armored personnel carrier wikipedia,the m113 is a fully tracked armored personnel carrier apc that was developed and produced by the food machinery and chemical corporation fmc. the m113 was sent to united states army europe to replace the mechanized infantrys m59 apcs from 1961. the m113 was first used in combat in april 1962 after the united states provided the south vietnamese army arvn with heavy weaponry such as
