Reference no: EM131285938
A new municipal drinking water treatment plant plans to obtain its water from the Ohio River. The city has contacted your engineering firm to design a treatment plant based on your expertise in monitoring the water quality of the river over the past few months. You are given the following background information for designing the plant:
Design Assumptions: Population: 100,000 people
Per Capita Use Rate: 165 gpcd
VOCs: Found in trace amounts
Algae: Levels below MCL
Fe: <0.3 mg/L
Mn: <0.05 mg/L
Chlorine Requirement: A continuous dosage of chlorine kills SO percent of the pathogens in 10 minutes of contact time. The municipality requires a 99.9% kill. Ammonia is abundant enough to produce adequate chloramine residuals of 0.5mg/L.
You are tasked to design a water treatment plant to treat this water source to an acceptable level so that it would be considered potable and palatable for human consumption.
Requirements:
- One-page single spaced memo hi 1 ightin4 major aspects of your design and unit operations.
- Appendix: o Synthesize your laboratory data from relevant experiments conducted during the semester and determine what treatment processes are needed (e.g., would hardness levels suggest a need for lime/soda ash treatment?).
o Draw an overall schematic of the treatment plant *
o Draw schematics detailing each of the unit treatment processes including cross sections/plan views with dimensions of basins, filtration media. etc.*
o Provide calculations of required dosages for chemicals and sizes of infrastructure, power input to water by paddle floeculators. etc (Clearly state any assumptions)
o Include printouts of any spreadsheets used in your final report.
Due Date: The final report will be due on Thursday, December Rth before the lab final. *Please provide professional renderings using software you are most comfortable with.
