4.0 Environmental & Reagent Information <br />The Whirlwind water treatment facility is fully self-contained within a 47-foot semi <br />trailer. Two reagents will be used in the treatment system: Barium Chloride and Ferric <br />Sulfate. The calculated chemical usage is show in table 4.1 below. <br />4.1. Reagent Storage <br />Barium chloride is supplied in dry powder form in 50# bags. The ferric sulfate is supplied <br />as a 50% solution in 55-gallon drums or in dry powder form in 50# bags. Up to two <br />drums of ferric sulfate solution can be stored on site with each drum containing about 660 <br />pounds of product. The dry reagents will be technical grade and will be 98 to 100% <br />strength. These reagents will be purchased in pallet quantities; typically pallets of <br />reagents aze supplied as 1000# net of chemical. Sufficient space is provided in the <br />treatment trailer to store one (1) pallet of each reagent. Thus the maximum anticipated <br />quantities of each reagent to be stored on site would be: <br />Barium Chloride: 980# (98% strength) <br />Ferric Sulfate: 1000# Dry (100% strength) or <br />1,320# liquid (50% strength) = 792 # FeSO4 <br />This will be sufficient dry bulk Barium Chloride for four to five months of operation and <br />Ferric Sulfate for over two years of operation. <br />Table 4.1 -Chemical Consumption for Water Treatment <br />'cal a Hate #H 5 day <br />Reagent gIL Gram ~~ #NYerar Tonsl Year <br />BaCI 0. 3,265. 7. 36. 2,528.1 1. <br />Fa9~'1 0.00487 530. 1. 5. 427.1 0. <br />4.2 Reagent Mixing and Usage <br />The reagent mix tanks have been sized to supply the design reagent dosing fora 9-day <br />period. The Mix tanks aze approximately 300 gallons each and will have the following <br />solution strengths: <br />Barium Chloride: 0.026% (+/-) <br />Ferric Sulfate: 0.004% (+/-) <br />Both aze very dilute solutions and present minimal health risk as a dilute solution. The <br />dilute solution of each reagent will be pumped into the treatment line via a metering <br />pump. The precipitation reaction will take place in the reactor tanks and the resulting <br />precipitate will be collected in the Settling Tank. <br />12 <br />
