Zero discharge toilets and onboard waste treatment options for a yacht

[rjp 4]

 

I'd be interested in how much DE you needed to use?  You can buy it from most pet shops, and probably other places, and I'd want a good stack of it on board - but how much of the DE you needed to use each time to ward off the the little beggars?

 

 

 

A cup of DE added seems to be enough.  I purchased a 4L ice cream container of the stuff at home and just leave a couple of 1C portions in ziploc bags on board.

 

Re the Coir -yes I use the compressed briquets. They are available at the local M10 and one spare on board takes up about the room of 1 sneaker.  All in the 'supplies' (Coir, DE and a couple of heavy plastic bags in case I need to empty the bin) take up less than a shoe box of volume.  A huge saving over the old holding tank.

A spoonful of brown sugar will take care of any urine (amonia) smells if you are using a larger container over a longer period.

 

We find a few Tablespoons of white vinegar in the empty pee bottle before installing in does the trick.  We also use a 1:5-1:10 diluted white vinegar as a spray to wipe out the bowl of any urine drops or #2 streaks after use.  That loo paper joins the used in the dry waste that we bag every 2-3 days.  With this regime we have not had any smell from the head, pee bottle or solid waste.
