Lectrasans use a batch process that requires a few minutes between flushes.
You could run a holding tank through it but it would have to be procesed
about a gallon at a time. Raratan has a holding tank option that wraps
around the Lectrasan. It holds maybe 10 gallons while you are in an NDZ and
has a pump and timer that feeds it to the lectrasan in batches automatically
when you are out of the NDZ..

After waste goes into the holding tank, can the system be plumbed to
then treat the waste with the treatment device, and discharge the waste
when the vessel leaves the no discharge zone, or is a pump-out the only
option to empty the holding tank?

However, any boat equipped with a treatment device only needs to have a
holding tank too--and use it of course--while in "no discharge" waters.
In fact, almost all boats fitted with treatment devices also have a tank
for use if/when they visit a "no discharge" harbor or marina.
