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.

8 Determine the solid loading rate on a secondary circular clarifier (diameter = 20 m) if the plant influent load is 2 ML/d. The recycle flow from secondary clarifier to the activated sludge system (aeration basin) is set to 10% of the influent load. It is also known that the aeration basin produces an MLSS (mixed liquor suspended solids) concentration of 3000 mg/L.

Two circular clarifiers operated in parallel service a single stage bio-tower system (plastic media) that receives municipal wastewater at an average flow (Qaverage) of 2000 m³/d, with BOD5 = 200 mg/L. The internal flow recirculation ratio is 2.4. The maximum overflow rate for the clarifiers is 1.8 m³/m²-hr. The design procedures require that the sizing of the clarifiers be based on "PEAK" flow which is twice the average flow (Qpeak = 2 × Qaverage), and media depth in the biotower is 3.0 m. Determine: (a) The overall BOD5 removal. (b) the surface area and the diameter of each clarifier. (k = 0.06 min¹; n = 0.5),
A closed tank of fixed volume is employed for the continuous mixing of two liquids, which enter at A, and B and are discharged completely mixed at C. The diameter of the inlet pipe at A is 150 mm and the liquid flows in at the rate of 56 dm3/s and has a specific gravity of 0.93. At B the inlet pipe is of 100 mm diameter, the flow rate is 30 dm3/s and the liquid with a specific gravity of 0.87. If the diameter of the outlet pipe at C is 175 mm, determine the mass flow rate, velocity and specific gravity of the mixture discharged.
