A sample of refuse is analyzed and found to contain 10% water (measured asweight loss on evaporation). The heat value of the entire mixture is measured in a calorimeter and is found to be 8000 kJ/kg. A 1.0 g sample is placed in thecalorimeter, and 0.2 g ash remains in the sample cup after combustion. What is the comparable, moisture-free heat value and the moisture- and ash-free heat value?

A BOD test is run using 100mL of treated wastewater. The initial DO of the mixture after diluting the waste sample with distilled water is 9.0mg/L. After 5-day incubation, the DO measured was 4.0mg/L. After a long period of time, the DO is 2.0mg/L and no longer seems to be decreasing. Assume that nitrification has been inhibited. Determine the following: a)BOD5 & BODu of the waste sample b) BOD5 of the mixture and c) k THANK YOU
The results of a jar test on a surface water supply sample revealed that the optimum dose of alum (Al2(SO4)3.14H2O) as coagulant is 17 mg/L. Furthermore, the water has total alkalinity = 50 mg/L as CaCO3; pH = 7.8; and residual turbidity at optimum alum dose = 4 NTU. The water treatment plant has a mean flow of 10m3/hour. Determine: The kg of alum per year needed in the operation of the plant. The residual alkalinity in the sample, following the addition of alum at optimum dose. Solve parts (a) and (b) if instead of alum, ferric chloride (FeCl3) were used as coagulant. Assume the numerical jar test results are the same as those with alum.
Calculate how much additional aeration volume (expressed as a percentage) is required to upgrade a BOD removal activated sludge plant under the following conditions: • Good nitrification performance by increase in Solids Retention Time (SRT). • 90% increase in SRT (Solids Retention Time) is achieved by 35% reduction in sludge waste flow rate. • Mixed Liquor Suspended Solids (MLSS) concentration in aeration unit (X) increased by 10% and settled solids concentration (Xr) is unchanged. State clearly any assumptions that you make.
A lagoon with volume 1200 m^3 has been receiving a steady flow of a conservative waste at the rate of 100 m^3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 10mg/L. Assuming complete mix conditions, if the concentration suddenly increase to 100mg/L, what would the concentration in the effluent be 7 days later (after the sudden increase of input concentration)?

A river traveling at a velocity of 12 km/day has a dissolved-oxygen content of 5.4 mg/L, and an ultimate CBOD of 32 mg/L at distance x 10 km, that is, immediately downstream of a waste discharge. The waste has a CBOD decay coefficient, ka, of 0.25/day. The stream has a reacration rate coefficient, k., of 0.45/day and a saturation dissolved-oxygen concentration of 9.5 mg/L.

You place a 20 g sample of solid waste in a drying oven overnight and find the mass in the morning (after the moisture has been evaporated) to be 16.2 g. A 1 g (wet) sample is also placed in a 1L water jacket bomb calorimeter and 0.18 g of ash remains in the sample cup after combustion. The temperature in the calorimeter is raised by 2.17 ˚C. Calculate the heat value on a wet weight basis, dry weight basis, and on a moisture and ash-free basis. Convert your values to BTU/lb
Problem 4In water and wastewater treatment processes a filtration device may be used to remove water from the sludgeformed by a precipitation reaction. The initial concentration of sludge from a softening reaction is 20,000 mg/Land the volume of sludge is 100 m3. After filtration the sludge solids concentration is 350,000 mg/L. Assume thatthe sludge does not change density during filtration, and there is no accumulation of sludge in the filtrationdevice. Using the mass balance method, determine the volume of sludge after filtration.
