Plate 2. <br /> Bavaro Property <br /> Nitrate Mass Balance Calculation <br /> (Evapotranspiration Method) <br /> Nitrate Loading Calculations: <br /> Variable Value Units Description <br /> Q 420 gallons per day Effluent flow rate from report <br /> Nw 35 mg/L-N Effluent stream concentration from report <br /> A 5.00 acres Site area from report <br /> Nb 1.00 mg/L-N Concentration of rain water from report <br /> d 0.20 constant Denitrification factor from report <br /> R 3.64 inches per year Recharge rate of percolating waters from report(evapotranspiration method) <br /> W 1.1 inches per year Uniform waste water loading for site calculation result <br /> Nc 7.4 mg/L-N RESULT: Long-term average concentration of percolating effluent <br /> Find Variable(W): <br /> (W) in = (Q) g_�i I x 1ft3 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 /> 1.13 in/yr(site)=420 gal/day x(1 cu-ft/7.48 gals)x(365 days/1 year)x(1 acre/43,560 sq-ft)x(12 in/1 ft)x(1 site/5 acres) <br /> Hantzsche-Fennemore Equation (Nc): <br /> Nc= WN...(1-d)+RNe <br /> W+R <br /> 7.39 mg/L-N=((1.13 in/yr x 35 mg/L-N x(1-0.2)) +(3.64 in/yr x lmg/L-N))/(1.13 in/yr+3.64 in/yr) <br /> Assumptions: <br /> 1. Total nitrogen concentration of influent waste stream is 35 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 20%. <br /> 3. Estimated deep percolation of rainfall is 3.64 in/yr. <br /> 4. Background nitrate-N concentration of rainfall is 1 mg/L-N. <br /> LOGE 1907 March 15, 2019 <br />
