Solids analyses were conducted on the meat-processing wastewater that was tested for BOD in Problem 3-42. The tests were conducted in triplicate. Based on the test data that follow, determine the concentrations of total solids, total volatile solids, suspended solids, and volatile suspended solids.

Problem 3-42:

A seeded BOD analysis was conducted on a meat-processing wastewater. Dissolved oxygen data for the seed test and seeded wastewater follow. The BOD bottles for the seed (aged, settled, domestic wastewater) were set up by adding 15 ml per 300-m1 bottle. The test bottles for the meat-processing wastewater were set up by adding 2.0 ml of wastewater and 1.5 ml of seed.

Based on the averages of three tests, the initial DO in the seed bottles was 7.9 mg/1 and the initial DO in the waste-water bottles was 8.1 mg/l. Sketch BOD-time curves for both the seed wastewater and meat-processing waste-water. Determine the 5-day BUD values and k-rates using the graphical procedure.
