Water and Wastewater Treatment

Professor: Dr J A Scott
Disinfection of water streams originating from potable water plants is key in protecting
environmental health. Briefly describe the type of microorganisms that are targeted for
removal and why, and then describe the process design and application, along with potential
processing advantages, limitations and disadvantages of using: (i) chlorination; (ii) UV light;
(iii) ozonation, and (iv) crossflow membranes to disinfect potable water from a municipal plant.
Information in your report should be fully referenced within the text, including any pictures
or diagrams copied and used. It must include an Abstract at the beginning (no more than
8 lines). The Abstract should be followed by an Introduction, then four individual
Sections (one per disinfection method). Follow these sections with a separate section that
discusses when a combination of methods is needed.
Finally, include a Conclusion that provides an overall discussion of the key points arising
from the entire report. The Conclusion should be no more than one page. Also make sure
you include at the end of the report a list of all References used in the text.
For a guide on how to use references in the text and compile a reference list, refer to the
separate Assignment Guidelines loaded up on D2L and/or an article in a refereed
engineering journal.
On-line encyclopedias, such as Wikipedia, are not acceptable as a reference – you must
quote the original source (e.g., journal article, book, technical report, company website
etc.).
Any blatant copying of other work, such as cutting and pasting of text from web
pages will be penalized.
Please place a hard (paper) copy of your report in my mail slot in the Engineering
School Office, on or before 19th October 2015. Soft copies (e.g., email attachments)
cannot be accepted.
This assignment is worth up to 30% of the overall course assessment
