Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.
When designing water treatment facilities, the main factors to be considered are the type of water source, finished water quality, the skill of facility operators and the available size of funds.
The following is the conditions for the water treatment plant:
Source: River
Flow: Maximum flow 10MG
Minimum Flow 5 MGD
Raw Water Quality
Turbidity range – 3ntu to 500ntu
Alkalinity – 20-40mg/L
TOC – 3 to 8mg/L
pH range – 6.5 to 9.5
Algae- occasional and has detections of cyanotoxins
Manganese- 0.04 to 0.5mg/L
Iron – 0.1 to 0.4mg/L
Ammonia – 0.3mg/L
PFAS – detections of PFOA only at 3ppt
Total Hardness – 50 to 75mg/L
Chloride – 50 to 300 mg/L
Sulfate – 50 to 200 mg/L
VOCs – not detected.
Pesticides and Herbicides – not tested
Area around the intake is light industrial and needs to be considered during the design
Assignment: Each group has to submit at least a PID or a CAD, minimum 10-page engineering report and a PowerPointpresentation summarizing their submission. This will be presented in the class by the group. The report has to describe any bench or pilot testing and a detailed description of the design. The report has to include detailed math equations needed for the proper design.

Make the presentation about the natural disaster of “1933 magnitude 6.4 Long Beach” and you get to add more than one natural disaster that is in Southern California. ALSO, THE PDF HAS ALL THE REQUIREMENTS FOR THE PRESENTATION FOLLOW IT. DO NOT USE Ai!!!!!!

Complete the attached worksheet. identify the significant changes and decisions (from one or more people, organizations, governments, society, etc.,) that either increased or decreased risk.
There’s a lot of moving parts – be complete. NOTE: the excel file has a ‘macro’ that you’ll need to enable in order to add rows. Also – do a spellcheck within excel before you submit. Always, always spell-check!
