ADJUSTED CONSTITUENT CONCENTRATIONS

FOR SURFACE IMPOUNDMENT MODULE 

FEP1

Flow rate = 347,234 gal./day

347,234 gal./day x 365 days/year = 126,740,410 gal./year

126,740,410 gal./year x 3.785 l/gal. = 479,764,642 l/year

126,740,410 gal./year x 3.785E-03 m3/gal. = 479,765 m3/year 

FEP2

Flow rate = 52,046 gal./day

52,046 gal/day x 365 day/year = 18,996,790 gal./year

18,996,790 gal./year x 3.785 l/gal. = 71,910,673 l/year

18,996,790 gal./year x 3.785E-03 m3/gal. = 71,911 m3/year

Total Flow Rate

FEP1 + FEP2 = 126,740,410 + 18,996,790 = 145,737,200 gal./year

FEP1 + FEP2 = 479,764,642 + 71,910,673 = 551,675,315 l/year

FEP1 + FEP2 = 479,765 + 71,911 = 551,676 m3/year

Sludge volume = 148 yd.3

148 yd.3 x 0.765 m3/yd.3 = 113 m3     

Sludge density = 1100 kg/ m3

Sludge mass = 113 m3 x 1100 kg/ m3 = 124300 kg

Adjusted Constituent Concentrations

 

Total constituent concentration x sludge mass / volume wastewater =
adjusted constituent concentration

Total concentration (mg/kg) x 124300 kg / 551,675,315 l = mg/l
