Grey Water Recycling
 

As rick says, I too can't find much about grey water recycling systems and
certainly nada when it comes to the type of boats we all sail.
I sure hope Binary Bill that clear this up. Otherwise.....

I think its time we let BB off the hook on this before he explodes! Its clear he isn't
prepared to engage in a battle of wits on this.

What BB said was:

"My C&C 27 doesn't have gray water tankage. If I took extended cruises
where fresh water was going to be in short supply, I would have gray
water tankage, along with a system for recycling it."

It seems pretty clear that there are no grey water systems for small boats, though I've
wondered if it would be feasible to save shower water for deck washdown. However, many
(most?) of the newer cruise ships do recycle gray water. They filter it to "near drinking
water quality" and use it, not for drinking, but for cooling systems and washing.

Clearly, BB wasn't talking about cruising on his C&C 27, but about the far more likely
possibility that he would take a cruise on a Holland America ship.

Thanks for clearing that up, Jeff. I had never heard of recycling grey water
for cruising boats. Even the mega yachts don't seem to have it. This exists on
Princess Cruise line ships and the like?

Nope, but he suggested it for his "larger boat" on a cruise where fresh water
was scarce. I guess he needs a lot of dishwater and has dirty decks that can't
be cleaned with a washdown/salt water fed pump!
Anyway...I feel pity for him, so I'll let it go...unless he rejoins the fray!

Yeah, but he was just starting to get the hang of tapdancing in 15/7 time....

Sure. Between hi tech filters and organic processing systems, you can bypass the natural cycle
and make pure water from almost any kind of waste water. The problmm is that the system has to
be fairly large and uses up large amounts of energy (from a small boat perspective, not so
much from a civil engineering view point).

Every drop of water on this blue planet has at one point been ingested then excreted by some
living organism. Stop and think about how much biomass vs how much water, for how many
billions of years. Of course, if you believe in voodoo economics then maybe you'd believe in
voodoo ecology too.

I think he has already - imploded - As for as it being a "battle of
wits" poor little Nul isn't even armed. Even Bush wouldn't claim Nul has
any weapons.

I am also sure he will be along shortly to impress us by posting some
recycled one-liner.

With the exception of spacecraft, wastewater simply is not recycled as
potable water. It is too expensive, too difficult, too risky, and too
offensive for all Earth based users. It is simply easier, cheaper, takes
less volume for the machinery, and is safer to process the local source.

Cruise ships recycle gray water for political and marketing reasons alone.

Only in NulWorld and JaxWorld do boaters drink gray water.

But then again, I don't know everything about every new technology and
maybe Nul knows about this gray water recycling system he would use if
he went on his extended cruise where water was in short supply. It would
be nice if he would tell us about it but he seems to be more interested
in pursuing his little hissy fit and won't share his information with us.

Ok, here's what I would do.

I generally know if the water I'm using is going into my body or not.
If not, why wouldn't I just dip up a bucket of whatever it is I'm
floating in for washing? Dip it up, use it, dump it out.

If you're sailing in some polluted waters, like the Hudson river, by
definition you are not far out of range of water you can trust. If
you *are* out of range of water you can trust, the water you're
sailing in is probably clean enough to wash with, and if you were
really worried about it, you could boil the rinse part first. I'm
thinking of dishes here.

For your body, a couple of cups of fresh water on a sponge should take
care of your personal needs for as long as you're out. On the Navy
ships I was on, we used sea water for the heads, and in areas of the
galley like the food disposals. Don't see why you wouldn't be able to
do the same on a thirty footer.
