Read the question carefully and give me all right solutions. If you don't know the solution please leave it but don't give me wrong solution. If the initial dissolved oxygen of a 3 mL sample is 7.5 mg/L and after day 5 is 5.5 mg/L, with a k rate determined to be 2 mg/L. what is the BOD5 ? Ultimate BOD ? BOD 2 ? BOD 10? . Create a BOD graph (time vs BOD) .
Determine how much extra volume is needed to treat the following wastewater in a CSTR than in a plug flow reactor. • Influent TOC: 273 mg/L • Required Effluent TOC: 57.0 mg/L • Flow: 792,500 gallons/day • First Order Microbiological Rate Coefficient (k’): 5.98/day Answer: 295,000 gallons 2. Discuss in detail at least two ways the k’ value may have been obtained and which technique is probably more accurate?
Problem 4. A receipt of surface water sample is given in Table below: Substance Concentration (mg/L) Total Hardness 1000 mg/L CaCO3 Phenolphthalein acidity 5 mg/L CaCO3 Phenolphthalein Alkalinity 3 mg/L CaCO3 It is known that phenolphthalein alkalinity is only due to CO3²- and phenolphthalein acidity is only due to H₂CO3. Assuming the hardness of sample is because of calcium and magnesium ions, alkalinity-acidity are due to the carbonate species, calculate: a) The pH of sample. b) Temporary and permanent hardness as mg/L CaCO3. c) Total alkalinity and acidity as mg/L CaCO3. Molecular weights (g/mole): Ca = 40, Mg = 24, H = 1, C = 12, 0 = 16
A waste water sample of 2 ml is made upto 300 ml in BOD bottle with distilled water. Initial DO of the sample is 8 mg/l and after 5 days it is 2 mg/1. What is its BOD?
Q1.Clearly indicate if each of the following is True or False 1) The amount of bypassed water in split treatment of hardness depends on material balance on Mg². 2) Most water treatment plants in Iraq are using polymers as a coagulant. 3) In drinking water, most of alkalinity comes from SO4². 4) Circle or ring system is the most common method used now to design water distribution systems. 5) Fecal Coliforms and E-Coli are generally pathogenic and we need to test them to avoid their diseases. 6) In flocculation process, we need rapid mixing to enhance formation of flocs for better settlement. 7) In filtration, the only mechanism involved is the straining. 8) It is better to travel downhill, avoid rush hours, and avoid left turn when designing a route for packers. 9) Ozone in Stratosphere layer helps prevent UV light from reaching earth and causing skin problems. 10) Transfer station is used to transfer solid waste to final destination in more efficient way.

2. A wastewater treatment plant disposes of its effluents into a stream at a point A. Characteristics of the stream at a location fairly upstream of A and of the effluent are as below: Item Units Effluent Stream m3 /s mg l1 Flow 0.20 0.50 Dissolved 0xygen 2.00 8.00 Temperature °C 26 22 BOD, at 20°C mgll 40 3. Assume that the deoxygenation constant K, at 20°C (base e) = 0.20 d-l and the re-aeration constant K, at 20°C (base e) Equilibrium concentration of dissolved oxygen C, for the fresh water is as follows: 0.40 d-1 for the mixture. %3D Temperature °C 18 20 22 23 24 25 26 C, (mg/1) 9.54 8.99 8.83 8.53 8.38 8.22 9.17 The velocity of the stream downstream of the point A is 0.2 m/s. Determine the critical oxygen deficit and its location. [Use temperature coefficients of 1.04 for K, and 1.02 for K,)
In a BOD test, the amount of organic matter remaining in the wastewater was measured at certain time intervals, instead of measuring the dissolved oxygen content. The amount of organic matterremaining after 4 and 9 d was measured as 52.86 mg/L and 8.11mg/L, respectively. Calculate the ultimate BOD and BOD rate constant k for the wastewater.
A sample of water from a surface stream is analyzed with the following results: Calcium = 98 mg/L, Chlorine = 89 mg/L, Bicarbonate = 317 mg/L Magnesium = 22 mg/L , Potassium = 71 mg/L, Sulphate = 125 mg/L i) Draw a bar diagram for the water, il) Determine the alkalinity of the water, ili) Determine the total hardness, carbonate hardness and non carbonate hardness for the water.
