WATER TREATMENT :- Begining of the process it constant the flow
WASTE WATER :- Begining of the process and at the end as well. Since the flow need to be maintained.

38 w Jersey requires that engineering design of water, storm, wastewater and air systens be colabor because within the space of 800 square miles, live about 3 milion people. This means each person can affect the ar 4u and water resources of another person. To add to the complexity of overlapping resource demands is the institutional complexity of independent municipal jurisdictions. There are over 150 separate municipal sewer and water utilities a separately elected munioipal council and mayor. Therefore, because...
Q5) (4 Marks) A wastewater treatment plant receives at an average 87% of water supply during dry weather conditions. Average, expected municipal water demand is 340 Lcpd. Population of the town is 45,000. Calculate: 1- Average dry weather flow 2-Hourly maximum dry weather flow.
A. Non-Texthook: Problem NT 4-3: 2 pts Given: A diffuser at the end of a 1.00 m diam., 9.00 km long ocean outfall pipe from the Hyperion Wastewater Treatment Plant (El Segundo, CA) discharges treated wastewater into the Pacific Ocean 7.20 km from Santa Monica beach. The wastewater contains 10 coliform bacteria per milliliter The wastewater discharge flow rate is 0.560 m/s. The coliform first-order death rates in the diffuser pipe and in seawater are 0.0500 h ' and 0.300...
Problem 4. Two communication systems (shown below) are composed from several links, where, for proper operation, a connection must be available between two end points of each system. For a link to work properly, it must provide a connection across its end points. The links are assumed to fail independently of each other. Each link is numbered with i, and we assume that the probability that link fails is equal to p Find the probability of failure of each system,...
(7) Problem 4-17 (15 points) Gasoline (approximated by octane) typically contains 0.1% sulfur by weight. If a passenger vehicle requires 3.5 MJ/km of primary energy, calculate the total annual mass of SOz produced by 250 million vehicles in the United States, each traveling 25,000 km per year.
Situation (note: Problem 2 is not linked with Problem 1): Assuming the design flow rate of raw wastewater to be treated is 20 MGD in the design year, the dissolved BODs is 380 mg/L, and SS is 360 mg/L. The wastewater generated by the sludge treatment process is about 4 MGD with the dissolved BODs being 1800 mg/L, and SS being 1200 mg/L, and will be returned to the wet well in the pumping station at the beginning of the...
Problem 4 (20 points) Consider the flow net shown below: The sides of the region are groundwater divides; the top boundary is the water table; and the bottom is an impermeable boundary. A) Label the equipotential with the appropriate value of hydraulic head (m); B) Draw arrows on the streamlines indicating the direction of groundwater flow; C) Label all recharge and discharge areas; D) Indicate at least one area within the flow net where flow is relatively fast, and one...

Problem 4: [12 points] There are two systems, each consisting of a large number of interacting atoms. For system 1 the entropy as a function of energy is S,-AE1/2, while for system 2 we have S,-BEV4 Here A and B are constants. The two systems are now placed in thermal contact, and allowed to reach equilibrium. a) [6 points Evauate E2 as a function of A, B, and E1 b) [6 points] What is the heat capacity of system 1...
A wastewater treatment plant that treats wastewater to secondary treatment standards uses a primary sedimentation process followed by conventional activated sludge process composed of covered aeration tanks and secondary clarifiers. You are asked to calculate the different operation parameters to make sure that the system is operated within normal process ranges listed in the reference tables below. Table 5-20 Typical design information for primary sedimentation tanks U.S. customary units Item Unit Range Typical Primary sedimentation tanks followed by secondary treatment...
