Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.

A pharmaceutical wastewater needs a minimum BOD/N/P of 100/3.0/0.7 for biological treatment. The wastewater characteristics are BOD = 740 mg/l, suspended solids = 250 mg/l, soluble nitrogen = 10 mg/l, and soluble phosphorous = 5 mg/l. What ammonium nitrate and phosphoric acid additions would you recommend to ensure adequate nutrients for a daily flow of 28 m3/d?
Sewerage waste was discharged into Mulungushi River from Iris lodge which is located along the banks of the river as they had a problem with a septic tank since it was full. This problem normally occurs in the rain season and this resulted in a mixture having DO of about 9mg/L. The average occupancy rate monthly is about 70%. The septic tanks are emptied after every two weeks. After 5 days, DO dropped to 3mg/L when ZEMA carried out the analysis of the water sample in the river. The reaction constant rate k was found to be 0.22 day ^(-1) and the oxygen consumed in the first five days was 200mg/L. a) How do suspended solids and chemicals affect the surrounding environment? Give two examples. b) What would be the ultimate carbonaceous BOD? c) What will be the remaining oxygen demand after 5 days? d) What advise can you give to the to the lodge owner as a Civil Engineer?
C A trickling filter plant treats 1500 cum per day of sewage with a BOD, of 220 mg/L and a suspended solid concentration of 250 mg/L. Estimate the total solid production assuming that primary clarification removes 30% of BOD and 60% of influent solids. Take the solid production in the trickling filter as a 0.5 kg/kg of the applied BOD.
The lowest flow in the Ozama River in July is about 48 m3/s. The dissolved oxygen concentration of the river just upstream of the discharge point is 4 mg/l and the ultimate BOD of the river is 10 mg/l. A farm discharges 2m3/s of untreated wastewater with a dissolved oxygen concentration of 0.5 mg/l and an ultimate BOD of 300 mg/l. Both the river and the discharge are at 25°C. what is the initial oxygen deficiency after mixing (i.e., as soon as the wastewater and the river have mixed)? What is the ultimate initial BOD after mixing? Can the farm be allowed to continue discharging raw water? Justify your answer.
