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.

2. Families in a community in a developing country use large, 200.0 L drums to un-treated surface water. You are designing a device that is designed to dose the volume with a coagulant, stir to allow flocculation, then add chlorine tablets to disinfect the water. The water is 25 °C and initially contains 1.0E+09 particles per L. The initial particles can be assumed to be spherical, 15.0 micrometers in diameter, and with a density of 1.675 g/mL. a. If the drums have a diameter of 572 mm, how long will it take for the particles to completely settle without any coagulation or flocculation? (answer in seconds) You have determined that you can achieve complete destabilization of particles by achieving an ionic strength of 0.01 M or higher. If you use alum (Al2(SO4)3) as a coagulating agent, what mass of alum must be added per batch of 200 L?

Poorly treated municipal wastewater is continuously discharged directly into a lake. The discharge from the wastewater plant into the lake occurs at a flow of Qd = 1 m3/hr. The concentration of phosphate (PO43, M = 95 g/mol) in the discharge flow (Cxd) that is decaying with first-order kinetics is 100 mg/L. The lake is a well-mixed water body of 100 m3. (Phosphate is naturally uptaken by algae with a first- order decay rate constant equal to 0.20/day.) The concentration of phosphate in the incoming river (Cx,r) is 10 mg P/L. The incoming river flow rate is Q, = 10 m3/hr. %3D a) Which of the following equations represent the correct mass balance equation?

Please upload your full solution to the following problem. A series of experiments was conducted in a batch reactor to assess the disinfection by chlorine of the protozoan Giardia lamblia. In each experimental run, the concentration of free available chlorine was varied and the time required to kill 99 percent of the organisms was determined. The results showed that a Ct value of 100 mg-min/L was sufficient to achieve 2-log removal. Assume that the Chick- Watson model holds with n = 1. A. What value is the psuedo-first order disinfection rate coefficient k (min ¹) when the chlorine concentration is 1 mg/L? B. At a chlorine concentration of 1 mg/L and a contact time of 10 minutes, what fraction of the G. lamblia organisms would be killed? C. At a chlorine concentration of 10 mg/L and a contact time of 5 minutes, estimate the fraction of the G. lamblia organisms that would be killed. 4
