Water samples (X and Y) from two different sources were brought to the laboratory for the measurement of dissolved oxygen (DO) using modified Wrinklier method. Samples were transferred to 300 ml BOD bottles. 2 ml of MnSO4 solution and 2 ml of alkaliodide-azide reagent were added to the bottles and mixed. Sample X developed a brown precipitate, whereas sample Y developed a white precipitate. In reference to these observations, the correct statement is

If the BOD5,30 of waste is 150 mg/L and the reaction rate constant (to the base 'e') at 20 C is 0.35/day, the ultimate BOD in mg/L is
A portion of wastewater sample was subjected to standard BOD test (5 days, 20 C), yielding a value of 180 mg/1. The reaction rate constant (to the base 'e') at 20 C was taken as 0.08 per day. The reaction rate constant at other temperature may be estimated by kr = (k 20 (1.047)T-20. The temperature at which the other portion of the sample should be tested, to exert the same BOD in 2.5 days, is
The following data are given for a channel-type grit chamber of length 7.5 m. (i) flow through velocity = 0.3 m/s (ii) the depth of wastewater at peak flow in the channel = 0.9 m (iii) specific gravity of inorganic particles = 2.5 (iv) g = 9.80 m/s , m = 1.002 10 3 N/s/m at 20 C, pw 1000 kg/m Assuming that the stokes is valid, the largest diameter particle that would be removed with 100 parent efficiency is
In a certain situation, wastewater discharged into a river,mixes with the river water instantaneously and completely. Following is the data available: Wastewater: DO = 2.00 mg/L Discharge rate = 1.10 m /s River water DO = 8.3 mg/L Flow rate = 8.70 m /s Temperature = 20 C Initial amount of DO in the mixture of waste and river shall be
50 g of CO2 and 25 g of CH4 are produced from the decomposition of municipal solid waste (MSW) with a formula weight of 120 g. What is the average per capita green house gas production in a city of 1 million people with a MSW production rate of 500 ton/day?
A wastewater sample contains 10 5.6 m mol/l of OH ions at 25 C. The pH of this sample is
Determine the correctness or otherwise of the following Assertion (A) and the Reason (R). (A): the crown of the outgoing larger diameter sewer is always matched with the crown of the incoming smaller diameter sewer. Reason (R): It eliminates backing up of sewage in the incoming smaller diameter sewer.
