SUMMARY OF KEY WASTEWATER MATH FORMULAS - Continued Oxidation Ditches: 4. Determine Sludge Age: a) Aeration Solids, = (Vol, MG) x ( MLSS, mg/l ) x ( 8.34 lbs/gal) lbs. b) Solids Added, = ((Vol, MG) x ( Inf. SS, mg/l ) x ( 8.34 lbs/gal) lbs/day c) Sludge Age, = ( Solids Under Aeration, lbs ) Days Solids Added, lbs/day 5. Calculate Ditch Volume

With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.

Jun 26, 2017 · C. Sample Calculation. Assume boiler is operating at 10 cycles of concentration with feedwater at 205 o F. This equates to a dissolved oxygen content of 0.7 ppm or 0.5 cc per liter. Assume a feedwater demand of 500,000 lbs per day. The desired sulfite residual is 30 ppm. 1. For fixation of dissolved oxygen: 0.7 ppm x 10 ppm = 7 ppm
