Introductions to Water and Wastewater Treatment Design Project

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 50 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 highlighting major aspects of your design and unit operations.

-Appendix:

• 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?).
• Draw an overall schematic of the treatment plant.
• Draw schematics detailing each of the unit treatment processes including cross sections/plan views with dimensions of basins, filtration media, etc.
• Provide calculations of required dosages for chemicals and sizes of infrastructure, power input to water by paddle flocculators, etc (Clearly state any assumptions)
• Include printouts of any spreadsheets used in your final report.
