Biological Processes

Biological solid waste includes bacterial and contaminated waste produced by living individuals. Its treatment is essential to prevent the spread of any air-borne or water-borne diseases or diseases transmitted from one organism to another in a food chain. There are many benefits of the biological solid waste treatment and some of them are: the minimized quantity of waste substance, waste control, eradicating any disease-causing pathogens, generation of biogas, composting, anaerobic digestion, bio drying, mechanical biological treatment, microbial fuel cell, phytoremediation, and biofiltration. The final products of the biological solid waste treatment may be recycled to obtain organic fertilizers or disposed of in SWDS (Solid Waste Disposal Site) after proper treatment.

A BOD analysis was conducted on a raw sewage sample. 300 mL of sample was placed in a 300 mL BOD bottle, and incubated for 5 days at 20°C. Based on your knowledge on the sample characteristic and BOD procedure, explain about the validity and the outcome of the analysis. 2. 3. Explain why oxygen depletion occurs when organic waste is disposed directly in the lake. And mention ONE adverse impact of oxygen depletion.
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.

A city wishes to discharge wastewater primary effluent to a river which supports a trout. The state requires the city to show that the trout population is protected. Trout require a minimum of 4 mg/l of dissolved oxygen to survive. Determine the minimum downstream dissolved oxygen concentration from the following information about the wastewater discharge and river. Does the minimum dissolved oxygen concentration meet the requirements? Wastewater discharge=0.45m3/s, river flow rate= 8.5 m3/s, river cross-sectional area=19m2, dissolved Oxygen concentration in the wastewater= 0.2mg/l, dissolved oxygen content of the river upstream = 8.1mg/l, saturation dissolved oxygen concentration at 20 C= 9.0 mg/l, BOD concentration in wastewater = 85 mg/l, BOD concentration upstream in the river= 0.2 mg/l, BOD decay constant = 0.2 d-1, and the reaeration constant for the river= 0.4 d-1.
