Never need to Dump again

New system eliminates need to dump RV holding tanks

If the invention by Namon Nassef takes off, many RVers will never need to dump their black water holding tanks again.

Nassef, president of Nassef Engineering and Equipment Company, has developed a new way to dispose of RV waste that uses green technology to eliminate sewage from RVs.

The ThermalTreat Zero Liquid Discharge (ZLD) Sewage Elimination System uses a small gallons or less sized tanks, grinds up the solids, and then dissolves the solids in the liquid. It then pressurizes this liquid and injects it into the hot exhaust gas of the engine. Steam and negligible minerals which come from the food people eat leave with the hot exhaust gas. The system is small, lightweight and uses no chemicals. It produces no odors, liquid, or solids to handle.

"We believe that there is a growing desire for environmentally friendly energy recovery methods to handle sewage," said Nassef. "It is our belief that when this technology is offered and demonstrated, the demand for it will be overwhelming since it is more efficient, cost effective and green. The current markets are huge -- valued at several hundred million dollars per year -- and the international market is immeasurable."

The ZLD processing unit without the EQ tank is approximately 12-by-18-by-24 inches -- the size of a medium suitcase -- and weighs less than 100 pounds. Still, it can process approximately 300 gallons per day depending upon available heat simply using engine exhaust to treat and dispose of sewage with no liquid discharge.

Nassef predicts it will eliminate large holding tanks in RVs, thus giving designers more storage space for other needs, such as clean water or cargo. It also eliminates the problem of dumping sewage holding tanks when there are no convenient places to dump, he noted.
Advantages of the system include:

• No odors
• No liquid discharge
• Energy recovery
• Environmentally friendly
• Small/lightweight
• Operable worldwide
• Operable in all climates and harsh environments
• Quick start/stop or storage/use cycles
• Plug-and-play design for replacement or repair
• Potential water reuse
• No chemicals required
• No sludge to dispose

a system like that was available in the 70,s dont know if it worked but the idea of hot exhaust gas being used to empty tanks is an old thought

Yes, thats what I thought as I was reading this. My boss had a Blue Bird
Motor Coach bac in the early 70's, and it had a sanitizer system as I recall. I only got rid of the waer at that time. As you drive it down the road, (once the engine is up to operating temperature) it would pump the liquid into a small port in the exhaust manifold. There it was turned to steam and out the exhaust pipe it went. It was installed prior to my taking it to Florida. We found out about 600 miles away when we tried to start the generator that they installed the tube into the exhaust manifold on the side that had the generator exhaust inserted into. Steam from the system went up into the generator and through an open exhaust valve, filling one cylender with water. Bad news for sure. Cost him a bunch to get it repaired.
Sure hope this one won't do that...

Whats old is new again!

My Fathers 1973 RecTrans Discoverer 22, with a 454 Chevy and a White chassis (Google it if you're curious) had a system like this that utilized the heat of the exhaust system to incinerate the macerated contents of the black tank. And no, I didn't work!

be the first to install this system. Sounds to me like there could be some real complicated problems including odor. I know what burning $h!t smells like and superheated steam leaves me wondering how it would smell.

[djbmsu]

We were in an RV park when someone fired up a system similar to this and last I saw they were looking for a tree to hang this guy. Stink didnt describe the smell and the black soot on the neighbors coach didnt go well at all. By the way the EPA requires "no visible emmissions" on all such systems so this may not even meet EPA standards.

[Glenn and Kathy]

So instead of dumping the tank every few days on an extended stay you either dump your smaller tank once, or twice every day, or disconnect and go drive around for a couple hours to burn up the contents.

Naw, believe I will stay with the old tried and true.

[B Bob]

This used to be an option on the GMC motor homes in the 1970's. There were some problems, LOL. Murphy's law was very much in effect. I used to own a GMC motor home and some of the old timers would talk about the system and there was a lot of laughing.

[rollondown]

A cheaper way would be the incinerator type toliets some of the older commerical fishing boats had. All enclosed, left nothing but ash

Kayjulia, sounds like you had a turn or two on the half barrels in Nam. That is on smell you will never forget. Can still dang near taste that smell....................

I don't know who taught this guy chemistry, but just because you grind up your s--t if doesn't automatically become soluble in water. At best this thing is going to produce a slurry of stuff that will enter the exhaust system. I would hate to think what the solids would do to the insides of the exhaust system including the muffler.

The person who concocted this thing obviously didn't consider what you are supposed to do when you are parked at one location on a long term basis and won't be running your engine. If you tried to use it without getting the engine to full operating temperature you surely would have a gunky mess in your tailpipe.

[TonyDi]

I don't believe I would want to ride down the highway behind someone who is in essence burning the contents of their black tank in their exhaust. I'll pass on this idea and continue doing it the old fashion way. It's not that big of a deal

[slickest1]

Geez, my rig is running kind of crappy today. Maybe I need to drive the crap out of it!
