• Q.0 Environmental & Reagent Information <br />• <br /> <br />The water treatment facility proposed for the Whirlwind will be fully self-contained <br />within a 42-foot semi trailer. Two reagents will be used in the treatment system: Barium <br />Chloride and Femc Sulfate. The calculated chemical usage is show in table 4.1 below. <br />4.1. Reagent Storage <br />Both reagents will be supplied in dry powder form in 50# bags. The bulk reagent will be <br />technical grade and will be 98 to 100% strength. These reagents will be purchased is <br />pallet quantities; typically pallets of reagents are supplied as 1000# net of chemical. <br />Sufficient space is provided in the treatment trailer to store one (1) pallet of each reagent. <br />Thus the maximum anticipated quantities of each reagent to be stored on site would be: <br />Barium Chloride: 9801! (98% strength) <br />Ferric Sulfate: 1000# (100% strength) <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 />or <br />!~ Grand week tf~lfear TanslYear <br />BaCI Q 3,266. 7. 3fi ~5ffi.1 1. <br />Fe904 Q 530. 5. 427.1 Q <br />4.2 Reagent Mixing and Usage <br />The reagent mix tanks have been sized to supply the design reagent dosing fora 5-day <br />period. The Mix tanks will be approximately 100 gallons each and will have the <br />following solution strettgths: <br />Barium Chloride: 0.043 to 0.059% <br />Ferric Sulfate: 0.007 to 0.01% <br />Both ate very dilute solutions and present minimal health risk as a dilute solution. Bench <br />scale testing indicates that these application rates will not result in increasing the <br />concentrations of barium, chloride, iron, and sulfate in the treated water above applicable <br />water quality standards. The dilute solu$on of each reagent will be pumped into the <br />treatment line via a metering pump. The precipitation reaction will take place in the <br />reactor tanks and the resulting precipitate will be collected in the sludge cell. <br />11 <br />
