A Look At Officer Training In The US Navy and Merchant Marine
In article n8mdnZuv57TM1wLEnZ2dnUU7-
, says... I admit, it is amusing to read your comments on a subject that you have absolutely no knowledge of. Tooling around on Long Island Sound or on the Chesapeake Bay on "YO HO" isn't exactly like being at sea on a ship that runs out of fresh water on the second day of a six month cruise and breakfast consists of powdered eggs, coffee or Bug Juice. You've never experienced "Channel Fever" either. What do they use to make bug juice? |

Both of my sons spent time on larger, more modern ships and according to them they never had lack of water or rationing. My only experience with reverse osmosis was with two smaller systems we had at one of the houses in Florida. One was in the kitchen that produced drinking water. Water was blah. The other was a somewhat larger system near the hanger. It had a 5 gallon storage tank that I used as a final rinse when washing the cars. The problem with both of them was that it took forever to replenish the water when the tanks were empty. Very slow process. === You had fresh water systems with no pressure pump. Salt water systems require much higher pressure and can be engineered to provide just about any flow rate. My wife and I get by just fine with about 20 gallons a day on average. How many crew on a destroyer? --- This email has been checked for viruses by AVG. http://www.avg.com |

The problem with both of them was that it took forever to replenish the water when the tanks were empty. Very slow process. It all has to do with the amount of membrane you have and the pressure you run at. Sanibel and parts of the Cape are on RO systems now but they are using brackish water from wells, not salt water. I have a small RO here, just for drinking water and ice makers. It makes about 8 gallons a day with new membranes and filters. As they age, that falls off. I get about 2 years out of a membrane and filters go about 6 months. I did put in a bigger cartridge filter with cheaper elements in front of the proprietary filters the RO uses. I have gauges throughout the system so I can monitor the operation. You can put a booster pump in front of the RO and increase your output. |
