Arrowhead Villas Mutual Service company will install a ~3 foot by 4-foot by ~10-foot prepackaged ion exchange treatment plant in an existing building (14 foot by 29 foot, area) that was constructed in the 1920's. The building had been used as a storage facility and an addition of a wall within the structure was constructed in 2015. The treatment system will use a strong base anion resin on which uranium will be exchanged for chloride and bicarbonate ions. The treatment unit will consist of bag fillers followed by 2 parallel trains of 5, 14-inch diameter contact vessels each, 10 total, operating in 2-paired series, designated as lead and lag. Each ~4-foot tall contact vessel will contain 3.3 cubic feet of ResinTech SBG2.
