Plate 2. <br /> Nitrate Mass Balance Calculations, Current <br /> American Crane Rental <br /> Nitrate Loading Calculations: <br /> Variable Value Units Description <br /> Q 221.4 gallons per day Effluent flow rate from report <br /> Nw 85 mg/L-N Effluent stream concentration from report <br /> A 11.80 acres Site area from report <br /> Nb 0.30 mg/L-N Concentration of rain water from report <br /> d 0.25 constant Denitrification factor from report <br /> R 3.64 inches per year Deep percolation of rain water from report <br /> W 0.25 inches per year Uniform waste water loading for site calculation result <br /> Nc 4.4 mg/L-N RESULT. Long-term average concentration of percolating effluent <br /> Find Variable(Vt/): <br /> (W) in = (Q) gal x 1 ft3 x 365 day(s) x 1 acre x 12 in x 1 site <br /> yr day 7.48 gal 1 year 43,560 ft2 1 ft (A)acre(s) <br /> 0.25 in/yr(site)=221 gal/day x(1 cu-ft/7.48 gals)x(365 days/1 year)x(1 acre 143,560 sq-ft)x(12 in/1 ft)x(1 site/11.8 acres) <br /> Hantzsche-Fennemore Equation(Nc): <br /> N,= WN (1-d)+RN, <br /> W+R <br /> 4.41 mg/L-N=((0.25 in/yr x 85 mg/L-N x(1-0.25))+(3.64 in/yr x 0.3mg/L-N))/(0.25 in/yr+3.64 in/yr) <br /> Assumptions: <br /> 1. Total nitrogen concentration of influent waste stream is 85 mg/L-N. If different influent concentrations exist,use weighted average <br /> 2. Fraction of nitrate-N loss due to denitrification in the soil is 25%. <br /> 3. Estimated deep percolation of rainfall is 3.64 in/yr. <br /> 4. Background nitrate-N concentration of rainfall is 0.3 mg/L-N. <br /> LOGE 1928 June 19,2019 <br />
