In a cattle farm, animal urine is decanted into a concrete storage tank, which is open to atmosphere. The storage tank occasionally receives rainwater, which is buffered with animal urine to pH = 8.5. It is well known that animal urine contains high concentration of ammonia with a pungent smell causing odor problem for communities nearby. Now, as an environmental engineering candidate you should be able to address the following questions: a) Which chemical process you would apply to control the odor problem on a temporary base. (10p) b) Which chemical process you would apply for the complete removal of ammonia from the urine wastewater. (10p) For each part (a and b) you should briefly explain each process along with specifying the name of chemicals used and reactions involved.
