Question #5.The fluoride feeder at the Lemieux Island WTP breaks down. As shown below, thewell mixed tank flows into a 5 km long distribution pipe. The volume of the tank is2.5 m³ and the treatment system serves 190 000 people who each use 200 L/d. Therest of the necessary data is provided in the figure. If the fluoride concentration inthe tank is 1.0 mg/L when the feed stops, how long until the concentration offluoride is reduced to 0.01 mg/L at the end of the distribution pipe? Assume thatfluoride acts as a conservative substance.FluorideC = 1.0 mg/L5 kmu = 0.17 m/s

Solution- No. of people = 190,000 volume used by each people = 200 litre/day discharge = Q=…

Drinking water from a dam which undergoes conventional treatment has a computed chlorine demand (due to silt, corrosion and bacteria) amounting to 3.5 ppm. Per PNSDW, such drinking water must have a mandatory chlorine residual of 1.0 ppm at source. If production flow is at 500 cu.m./day, calculate the chlorine dosage needed in pounds per day (PPD).
A wastewater treatment plant will receive a flow of 30,000 m3/day. The plant has a 3.6 m deep circular primary clarifier with a surface overflow rate of 60.0 m3/m2-day.a.

How long will it take a 1.0 mm particle with a density of 1500 kg/m3to settle in the primary clarifier? show all work
A waste-holding lagoon situated near the main plant of a chemicalcompany receives sludge on a daily basis. When the lagoon is full, it is necessary toremove the sludge to a site located 4.95 kilometers from the main plant. Currently,when the lagoon is full, the sludge is removed by pumping it into a tank truck andhauling it away. This process requires the use of a portable pump that has an initialcost of $800 and an 8-year life. The company can operate the pump at a cost of $25per day, but the truck and driver cost $110 per day.Alternatively, the company has a proposal to install a pump and pipeline to theremote site. The pump would have an initial cost of $600, a life of 10 years, and acost of $3 per day to operate. (a) If the MARR is 15% per year and the pipeline willcost $3.52 per meter to construct, how many days per year must the lagoon requirepumping to justify construction of the pipeline? (b) The lagoon was pumped40 times last year. Which alternative would have been cheaper?…
Answer and show complete solution. Pls don't rejectA factory discharges waste water to a nearby river. The concentration of dissolved oxygen (DO) a few meters downstream of the factory’s discharge point was recorded for 10 consecutive days as shown in the table below.
