What is a raised frame to keep out water?
Coaming
What is the total process the distilling plant forms, including evaporation and condensation?
Distillation
What is the Chlorine available (after demand is met) in the forms of Hupochlorous acid and Haypchloriet ions?
Free Available Chlorine
A unit of length. One miilionth of a meter?
Micron
Treatment device applied to a single tap used for the purpose of reducing contaminants in drinking water at that tap
Point of Use
Water that is suitable for human consumption, bathing, laundry, personal hygiene
Potable Water
The Reverse of the natural osmosis achieved by external application of sufficient reverse pressure to cause the solvent to flow in its unnatural direction
Reverse Osmosis
- Group of closely related, mostly harmless bacteria that live in soil as well as the guts of animals
- Presence or abscence of this bacteria is the drinking water standard
Total Coliform
Type of fecal coliform bacteria commonly found in the intestines of animals and humans.
The presence of this bacteria in water is a strong indication of recent sewage or animal contamination
E. Coli
Responsible for the shipboard potable water systems, including treatment facilities and processes to assure that safe drinking water is available at all times
Naval Sea Systems Command

The water has to be treated to a minimum of 2.0 PPM
What are the 3 types of Distillation Plants?
- Steam Distilling Plants
- Waste Heat Distilling Plant
- Vapor Compression Type
What are the 2 types of Reverse Osmosis Plants?
- Single Pass
2. Triple Pass
What does a single pass, Reverse Osmosis plant require when preparing potable water?
Additional disinfection such as chlorination or bromination is required
