The discharge should be odor-free when it leaves the ES--in fact, odor is an indication that the waste isn't being treated...but although it reduces bacteria count to <10/100 ml, if even ONE li'l ol' bacterium survives, it's gonna multiply into zillions in the tank very quickly, especially in hot weather.* So unless the tank is well enough ventilated to keep it aerobic, it's gonna stink whether waste is treated before going into it or not.*Tidahapah wrote:Peggy with the discharge from the Electro Scan going to a holding tank will it require cross flow ventilation or will the discharge liquid be smell free.
However, I'd rethink sending everything to the tank, 'cuz the discharge from a treatment device MUST go directly overboard for it to be "treated waste."* If it goes into a tank instead, for the very reason I described above it ceases to be treated waste...it becomes no different from waste that goes into the tank directly from the toilet...and you cannot legally dump the tank anywhere that you can't dump a tank of raw waste.* So sending it all to the tank first defeats any advantage to having a treatment device.
As for venting the tank, cross ventilation may not be the best answer or even necessary. A single 1"-1.5" short straight vent line to a thru-hull that faces forward can accomplish more.
Email me, we can discuss specifics of an installation that'll work best for you.
Shower TANK?* Not just a sump?* Hooboy...gray water tanks are a nightmare to maintain!* Frequent pumpout and thorough rinsing out are about the only thing you can do for 'em.AllanY wrote:I have a Lectrasan on Nevia and when I fitted the holding tank I fitted a vent however there is more smell coming from the shower tank than from the toilet system.
However, if it IS just a shower sump, keeping clean and odor free is actually easy...just about the only maintenance job on a boat that requires no manual labor:* Once a week when it can stand at least overnight--or just before leaving the boat (it can stay in the sump indefinitely without harm) empty it, then run enough clean water down the drain to fill it about 1/3 full.* Squirt 2-3 oz of Raritan C.P. down the drain.* http://www.raritaneng.com/products/cleaning_maintenance/cleans_potties.html
C.P. is a bio-enzymatic cleaner that Raritan only markets as a toilet bowl cleaner, but it's also the best sump and drain cleaner on the planet, because it not only destroys odor on contact, but the enzymes in it "eat" hair, soap scum, grease, body oils that build up in drains and cause sumps to turn into primordial soups.*
If that were true, don't ever flush your toilet either because that would not only wear out the discharge impeller, but also the joker valve! Guess what: They all* DO wear out...as does everything else on a boat!* Replacing 'em on a schedule is called "PREVENTIVE maintenance" because it prevents a lot of the head aches caused by waiting till they fail.koliver wrote:Peggy: What you say about wear on the impeller sounds a lot like, "don't think you can actually use that pump to self-prime, as you are wearing out the impeller if you do".
