I sometimes stay up late.

Do you think that the clorine dispenser used in Raritan Purasan (or
equivalent device) can be added to the holding tank?
the set would be: electric macerator, tank, clorine dispenser...
Just one idea...

Not a good one, I'm afraid...for several reasons. The PuraSan dispenser
is designed to deliver enough cholorine to treat each flush of the
toilet--one gallon or less. The toilet flush water washes through it,
carrying away just enough from the solid block of it...then the PuraSan
mixes and macerates that flush for 2 minutes. A whole tankful at a time
going through the cartridge would wash away most of the entire block,
but wouldn't be in contact with the waste long enough to "sanitize" it.
Nor would adding chlorine--or any other chemical--to a tank meet any
legal requirement in the world for "treated" waste. Even waste that's
been treated by a legal device before going into a tank is no longer
considered treated once it does. So nothing is accomplished by adding a
chemical to the waste before or during dumping the tank.

If the discharge of treated waste is legal in your waters, consider
installing a PuraSan or Lectra/San instead of a tank. More expensive
than a tank, but beats the socks off carrying waste aboard and all the
hassle of maintaining a tank if you don't have to.

You look at the idea from a legal point o view...
My target wasn't to comply with any law, but is one attempt to find a
radical solution to odor control.
In your articles you talk about a sanitizing device that works both as type
1 and type 3...
Sometingh like that...
But custom made to fit in the available spaces...

The related laws are changing here... Don't know how it will be in the near
future...

I like it, but, disregarding the cost, it can't fit... I am building a small
cat...

Anyway Your comments have helped a lot to clarify the problems.

I will try to find one standard tank, if unable to find a suitable one (one
that make efficient use of available space), i can have one custom made here
in Italy or from one of the suggested european manufacturers...

Tank you!

It wouldn't work. Oxygen is the key to eliminating odor. Odor can only
be generated in anaerobic conditions.

1 and type 3...

I've been trying to get that d'd article off the 'net for 3 years! Most
sites have complied willingly, but a few have just ignored all requests.
I haven't revised it since 1996...much of the information in it has
become obsolete since then (which is why I want it off the
net!)--including the reference to the device you mention, the SeaLand
SanX system, which was discontinued a couple of years ago.

However, it didn't work quite the way you seem to think it does...the
chemical (TDX, which is a NASTY formaldehyde based witches brew) doesn't
eliminate odor, but actually adds a horrible chemical odor to the waste
stench (I owned a boat that had this system, btw). The SanX tank holds 9
gallons...a quart of TDX is injected...the mixer and macerator run for
20 minutes...then a relay kicks on the separate discharge pump to empty
the tank....and the discharge STINKS...if you dumped the tank in the
slip or in an anchorage, you'd likely be shot.

Sometingh like that...
But custom made to fit in the available spaces...

You're over complicating it, and it won't accomplish what you want to
accomplish either. Venting the tank to allow plenty of fresh air flow
through it, or aerating the contents, will completely eliminate odor out
the vent from the tank without chemicals...and a tank is legal everwhere.
If the discharge of treated waste is legal in your waters, consider
installing a PuraSan or Lectra/San instead of a tank. More expensive
than a tank, but beats the socks off carrying waste aboard and all the
hassle of maintaining a tank if you don't have to.

The Lectra/San and PuraSan are smaller than any tank big enough to hold
more than half a dozen flushes. Check the dimension he

Get back to me before you order or build anything...we need to talk
about fittings sizes and locations. And we should prob'ly discuss which
toilet and how to plumb it too. Meanwhile (at the risk of being
perceived as trying to sell you something), you might consider checking
out the link in my signature...the information in it IS current.

mmmhhh... maybe, modifying the forward port bert...
The exaust from purasan can be temporary dumped into one holding tank? there
are a lot protected "absolutely no discarge" areas here, mediterranean sea
is almost a close sea...
The double function: holding tank and sanitation device was, in my
understanding, the interesting feature of sealand SanX...

Get back to me before you order or build anything...we need to talk

toilet and how to plumb it too.

The idea was the Blakes Lavac or alternatively one electric model...
The electric have a simpler, more linear plumbing.

About the plumbing it can't be a problem: any usable tank position is less
than 3' away, and also the sea is there, mi hulls are narrow...
If requested i can use pure gold and probably I will remain into the
buget...
Ok, I am kidding, but you get the idea....

I will explore it accurately...
