Hey Peggie / Group - LactraSan question
wrote:
Whoa! I didn't realize the list of NDZ's was so extensive...
Actually, it's not in coastal waters...most on that list are just very
small harbors and inland waters.
On boats
equipped with LactraSan, is it SOP to also install a holding tank with
'Y' valve? That is, when in the marina or less than 3 miles offshore
(I'm in SoCal) one directs the outflow from the LactraSan (via the 'Y'
valve) into the tank, and when greater than 3 miles offshore, the valve
is switched to overboard discharge?
Yep.
May I assume that - in the process of 'processing' - the LectraSan
removes / minimizes the odors associated with products presented to it?
In other words, if one has the 'Y' valve in the 'NDZ' position
(filling the tank) are the nasties generally associated with holding
tanks minimized?
Yes...and no. The discharge from the Lectra/San is odorless...in fact,
ANY odor--inside the boat or in the discharge--is a sign that it's not
working. However, although the L/S reduces the bacteria count to 10/100
ml (the law only requires it to be 1000/100ml), only one of the li'l
buggers has to survive in the tank to multiply into zillions VERY
quickly, especially in hot weather. So while there is LESS potential
tank odor--or at least it takes longer to get bad--from waste in a tank
that's been treated first, the same principles and maintenance are
needed to keep the tank odor-free as are needed for waste that hasn't
been treated first.
So while Raritan recommends putting the y-valve AFTER the L/S, when it
comes to odor prevention, it really doesn't matter much whether the
y-valve is before the L/S or after it.
