unevty mausecondary municipal wastewater effluent can be reused for variouspurposes. One such application is currently practiced at Water Factory 21 in OrangeCounty, California. Wastewater effluent (pH = 8) is treated by a number of processes,and the final product water is recharged into an aquifer with the main purpose ofcontrolling groundwater degradation due to seawater intrusion. One of the treatmentprocesses included in this plant is air stripping, a process in which volatile contaminantsare volatilized from water and transferred into air. Ammonia (pK,-9.3 at the designtemperature of 25°C) is one of the original target contaminants to be removed byvolatilization.(a) Indicate if pH adjustment is required prior to the wastewater entering the air strippingtower, and if so what type of adiustment you would recommend (pH increase ordecrease). Justify your answen(b) Indicate if the pH in the water exiting the air-stripping tower would tend to be higher,same, or lower compared to the adjusted influent water pH. Justify your answenrpoints)
