As an environmental engineer, you want to measure the BOD5 of a real wastewater sample. You dilute 30 ml of your sample with pure water to make a standard 300 mL BOD solution with an initial DO of 10.0 mg/L. To ensure an accurate test, it is recommended to have at least a 2.0 mg/L drop of DO during the five-day test, and the final DO should be at least 2.0 mg/L. In what range of BOD5 of original wastewater sample, you will get convincing results by using this testing process?

Assume that all solutions are prepared at 25 degrees celsius and the solutes arr completely dissolved. In the lead content analysis of a wastewater sample, 75.00 mL of the original sample was taken and diluted with 125.00 mL deionized water. The diluted sample was found to have a lead content of 19.2 ppb. What is the lead content (in pbb) of the original wastewater sample?
A wastewater sample subjected to standard BOD5 test yields a test result of 200 mg/L. The rate constant is 0.18/day at 20°C (to the base 'e'). Another sample of the same wastewater is tested at a temperature of 30°C. The time in days after which the BOD yielded is 200 mg/L is (up to 2 decimal places).
3. A 100 mL of wastewater sample was drying on a 0.5 g empty dish weight at 104 °C to weight 0.5625 g. Another 100 mL of the same wastewater was first filtered and the filtrate was dried on a 0.5 g dish at 104 °C to weight 0.5325 g. Determine in mg/L the:a) TSb) TSSc) TDSd) VSS assuming it represents 70% of TSS
A BOD test is to be run on a sample of wastewater that has a five-day BOD of 195 mg/L. If the initial DO of a mix of distilled water and wastewater is 9.0 mg/L, and the test requires a decrease in DO of at least 2.0 mg/L with at least 2.0 mg/L remaining at the end of the five days, what range of dilution factors (P) would produce acceptable results? In 300-mL bottles, what range of wastewater volumes could be used?
A 5-day BOD test if performed on an industrial wastewater sample that contains no bacteria; therefore, a "seeded" BOD test is run. Ten ml of "seed" are added to 20 liters of dilution water. Thirty milliliters of industrial wastewater are added to a 300-ml BOD bottle, and the remaining volume consists of "seeded" dilution water. The average dissolved-oxygen concentrations of the diluted wastewater samples and blanks (seeded dilution water) on the first day of the test were 7.5 mg/L and 9.0 mg/L, respectively. After incubation of separate BOD bottles at 20 C for 5 days, the average DO concentrations of the diluted wastewater BOD bottles and seeded dilution water BOD bottles were 3.1 and 8.5 mg/L, respectively. Calculate the 5-day BOD of the industrial wastewater. I am unsure of how to solve for f given this information, where f = (% seed in D1) / (% seed in B1)

In the lead content analysis of a wastewater sample, 25.00 mL of the original sample was taken and diluted with 175.00 mL deionized water. The diluted sample was found to have a lead content of 12.7 ppb. What is the lead content (in ppb) of the original wastewater sample?
A wastewater sample was diluted 10% with tap water for conducting BOD Test. The DO content in wastewater sample was 1.2 mg/l and water was 6 mg/l. After 5 days incubation at 20°C, the DO of the sample was 0.5 mg/l. Calculate (1) 5 day BOD of wastewater and (ii) ultimate BOD. Assume K₂ = 0.12/day.
A standard BOD test is run using seeded dilution water. The blank bottle containing the seeded dilution water has an initial DO of 9.2 mg/L and a final DO of 8.2 mg/L. The waste sample is mixed with seeded dilution water at a 1:25 ratio. It has an initial DO of 9.0 mg/L and a final DO of 2.0 mg/L. Calculate the BOD5.
Problem 1. A wastewater sample is examined for its solid contents. The ionic strength (μ) of wastewater is 0.01. It is known that 30% of total dissolved solids (TDS) is organic. The volumetric settleable solid concentration is determined as 20 mL/L using Imhoff Cone. It is assumed that 40% of total suspended solids (TSS) is equal to dry-settleable solids. The volumetric settleable solids composes of 2% of dried solids and 98% of water. The density of volumetric settleable solid concentration is given as 1020 g/L. Use information given in problem, calculate: a) Total Dissolved Solids (TDS) concentration as mg/L. b) Total Suspended Solids (TSS) concentration as mg/L. c) Total Solids (TS) concentration as mg/L.
