1 Embalming is not required with cremation unless the body will be on display, or if there will be a long delay between death and cremation. 2  If embalming is done, it can cost $200-$700 or more. 3  See How Much Does Embalming Cost. 4  The body must be in a container when it is cremated.
When designing columns, it is common to define the design reflux ratio as some multiple of the theoretical minimum reflux. The cost optimum reflux ratio is typically in the 1.1 to 1.5 range depending on energy costs, condenser coolant, and materials of construction. The rule of thumb reported most often suggests that a reflux ratio of about 1.2 times the minimum is a good design value. It may also be necessary to distinguish between returned reflux (the reflux stream flowing from the accumulator to the column) and the effective reflux flowing down the column.
The average first-stage effluent BOD5 concentrations during warmer and colder periods were 50 and 73 mg/L, respectively, with associated NH4-N levels of 10.0 and 11.4 mg/L, respectively. The BOD5 loading in the second stage averaged 42.5 g/m2/d (8.5 lb/1,000 ft2/d). The average monthly effluent BOD5 concentration was consistent throughout the study year, ranging between 6 and 18 mg/L. The effluent NH4-N level averaged 4.7 mg/L during the warmer months and 5.9 mg/L during the colder months.
