Collection Systems

The collection systems form a part of sanitary engineering, which is a sub-branch of civil engineering. It is also known as public health engineering and wastewater engineering. It is a methodology followed to remove and properly dispose of human waste, along with creating systems to provide safe and clean usable water. These measures ensure a hygienic and disease-free community. Sanitary engineering, apart from building sewer disposal units, is also involved in plumbing, fire protection, hydraulics, life safety, environmental protection, information technology, microbiology, pathology, and so on.

Question

A company spilled a contaminant that got into
the water distribution system of a small town,
which has an average flow of 100,000 gpd. The
contaminant infiltrated a pipe 1,500 ft from the
storage tank, and the concentration at the
infiltration point is 5 mg/L. The storage tank has
a volume of 125,000 gallons and the first user is
500 ft from the storage tank. Assume velocity of
2.5 ft/s in pipes, and a rate constant of 3/day.
What is the concentration at the first user?

2.10. Water leaves a treatment plant in a 500-mm diameter ductile-iron pipeline at a pressure of 600 kPa and at a flow rate of 0.50 m³/s. If the elevation of the pipeline at the treatment plant is 120 m, estimate the pressure in the pipeline 1 km downstream where the elevation is 100 m. Assess whether the pressure in the pipeline would be sufficient to serve the top floor of a 10-story building (approximately 30 m high).

A jar test reveals that the optimum alum coagulant dose is 50 mg/L at a pH of 8.1 and a temperature of 73 F. How many pounds per day of 49% alum are required for the whole plant? Total flow is 36 MGD with four parallel treatment plants, each designed for 12 MGD. Could use some guidance on setting up the equations.
A system is designed to treat contaminant X with two PFRs in series. The concentration of contaminant X entering the first PFR is 120 mg/L and the inflow is 420 L/s. The first PFR is 5000 m³ in size, and the contaminant reacts via first order kinetics with a k value of 0.50 (1/hr). The second tank is being built so that the treatment facility can meet the permit level for contaminant X of 9.4 mg/L. What size do they need to make the second tank in m³?
