A plant treats 25 MGD at 5°C and pH=7.0. The plant uses ozone before the filter and free chlorine after the filter. The ozone contactor has a t10 of 3 minutes and a residual concentration of 0.3 mg/L. The free chlorine contact basin is 65 ft by 214 ft by 10 ft and a baffle factor of 0.5 and a residual concentration of 1.4 mg/L

- Match the term from the Clean Water Act with its corresponding definitions National Pollutant Discharge Elimination System (NPDES) Total Maximum Daily Load (TMDL) Best Available Technology (BAT) Point source pollution A The maximum amount of a pollutant that a water body can receive while still meeting water quality standards. B. A permit program that regulates the discharge of pollutants from point sources into the waters of the United States. C. A specific location, such as a pipe or ditch, from which pollutants are discharged into a water body. D. A technology or treatment method that is determined to be the most effective way to control pollutants based on factors such as cost and feasibility.arrow_forwardEach gate of the lock is 6 m high and is supported by two hinges placed on the top and bottom of the gate. When the gates are closed, they make an angle of 120º. The weight of the lock is 5 m. If the water levels are 4 m and 2 m upstream and downstream, respectively, determine the magnitude of forces on hinges due to the water pressure.arrow_forwardQuestion 5 A submerged sharp crested weir 0.8 m high stands clear across a channel having vertical sides and a width of 3 m.

Find the head on the weir in meters.arrow_forwardAs a strategy of the Salahadin Government to extend the residency community in Tikrit City, there is a plan to provide water for a new residential area on the west side of Tikrit City, as shown in the map in Figure 1. The new residential area is exposed to have 25000 residences, three schools to serve 1000 students, and a Plaza Markt that can serve 2000 persons. The water will be supplied from a purification station installed on the Tigris River at an elevation equal to 130 m. The distance between the water purification station and the center of the new residential area is about 9.5 km, and the elevation of the city center is about 150 m. The required pressure in the new residential area center is 30 m. The available pipes in the market with their price are shown in Table 1. Also, the price for each 10-meter of pump head is 1500$. Your task as environmental engineers is to design a sustainable and economically viable water system, including the main pipeline and pump for the new…arrow_forward

Assuming the beam is fully laterally restrained and there is nominaltorsional restrain at supports, select a suitable UB section in S275 steel to satisfy bendingand shear considerations. Also, check the selected UB section against the deflection.
