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.

Assuming that the specific gravity of the following substances is approximately the same, that is, 2.65, and that the water is at 20°C, calculate the time it will take to settle 1m of the following materials: a) Gravel (Dp=10,000 μm) in seconds I want help with this one, I did the problem but the time gave me 36.36 seconds and the Dr told me that the result is incorrect, I would like to know how to do it. I used the formula of V=Dp^2(g)(△p) / 18μ ; Then use a substitution to calculate the time which would be t=h/v
Determine leachate generated in a cell in a 12-month period. You may assume that: -Percolation through the cover is 15in -Water consumed by waste decomposition is negligible (Life 1 contains mostly fresh waste) -Water loss as water vapor in landfill gas is negligible (again due to fresh waste) -Initial moisture content in fresh waste = 0.20 -Weight of waste in the lift = 3000 lb/yd² -Weight of cover = 1500 lb/yd² -The following sketch depicts water in and out of a waste lift. Water consumption by waste decomposition PER or leachate from above Water stored in waste Leachate generated Water loss as water vapor in landfill gas
