I posted a thread at
International Cannagraphic Magazine Forums - 100% odor erasing solution
Hope get some feedback.

Regards!

That's quite a setup. What kind of $ figure would you estimate for what you describe. I'm just curious. It really would be nice if you posted the info here rather than a link.

dr gonzo

seems cool

so it sprays into the air or into itself?

I have three of those...but man do they take up a lot of room and power....

Good article pg.

The project was implemented for most, and I have done some experiments and tests for 3 months. The testing results are very good:
All malodor were removed completely. Due to some Patent Application issues, I will post my experiment thread and product photos later.
I will post my new thread on this forum instead of a link. Sorry BM:-)
BTW, I try to answer other two questions:
For sprayer, My design is based on Solution B, which means Nozzles spray out very tine mist(fog) to 'meet' air. So it like some kind of 'washing Air'. Using some tech, I can make sure all melecula of air (including Pyrrole, Pipederine etc) will be washed at twice when they pass through the Tank.
For next question, It will not take too much space and power:
For space, e.g., 2 feetby 2 feet by 6 feet cubic cab is enough for a 3~5kw growroom, and entire power is just 30W.
Actually, there are several benifits could be provided from this system:
1) 100% Odor erase (Remove All);
2) Very small electrical consumption is needed(<-30W);
3) an Air Cooling system is provided due to misting fog can cool down air temperature 5~15 C;
4) Silence System-misting pump’s noise is around 40~50db;
5) Very easy maintenance – per month change water, ethanol/Industrial Alcohol and acids, check the misting pipes and misting nozzles etc.
6) Very low running fee – per month change water, ethanol/Industrial Alcohol and acids, check the misting pipes and misting nozzles etc. 1 pound compounded solid acids just cost you $40 per year and Industrial Alcohol is also very cheap.
7) Very long lifetime for usage: Reaction Tent - >10years, Pump Motor – 10years, Pipes – 10 years, Misting Nozzles - >1 year (very cheaper to replacement), Water Filter Shell – 10 years; All under proper usage condition.

I like your idea and wish you all the best.

wow! thats not an odor removal solution ive seen before.

if it costs 50 bucks, i think im in, lol.

very cool - I'm looking forward to checkin' out the finished product when you can show it to us. And probably buying one if it works lol.

I was not 1st guy have this idea. Actually, in 2002, One guy had been posted a thread in this forum and asked some one to make same kind of product which copy from Industrial style Air-Wash (Misting Odor Control).
Industrial Odor Control Solutions, there are many methods. I index them by solution, efficiency, set-up cost and running cost to make a comparison.
Solution Efficiency Setup Cost Running Cost
1)ionization High >1M$ Low
2)O3 Low Cheaper High(O3pipes replacement)
3)Air-Wash(Misting/Fog) M Cheaper Cheaper
4)ActiveCarbon Low Cheaper High

You can use google with "Misting odor control" to search and will get over 100K results.
My contributation is: Make these industrial products down to Family standard.
Thanks your feedback and I will give your the final asap.

Section2: Testing

--------------------------------------------------------------------------------

Testing - Water Flow:
This test was meant to show the actual performance of the pump and nozzles when in operation and to compare that data to the performance rating given by the components. The pump has a rated capacity of 1 gpm (gallons per minute), the misting nozzle has a rated capacity of 2 gph (gallons per hour). It is necessary to see if the configuration set up for the transfer of water from the pump through the nozzles and into the device matches expected values based on performance ratings.

The test consisted of placing 10 nozzles into a tank of known volume with 10X2=20gph or 0.33gpm capacity. So, the pump has enough capacity to fill these nozzles. For the misting system, there are two mesh grid filters to hold the misting water. So basically, all malodor molecules are washed when they penetrate the filters. Meanwhile, these two mesh grid filters plus mist play other function role – dehumidify. Because, when intake air meet with mesh filters, water molecules (very tine) was absorbed by other large water molecules group, and vapor state change to liquor state as well. Then, this liquor droplet becomes bigger, finally, dropping into reservoir. This procedure is very similar with rain generation loop. My testing result indicates 80%~100% humidify intake air was dehumidified to 60~70% humidify (outtake air).
Testing – Odor Remove:
As with the odor remove test, this test was designed to measure the effective performance of the system vs. malodor materials such as pyrrole, pyridine etc.
The test env is listed as following:
1) one plastic box as misting system’s tank, the box size is: 2(W)X3(L)X2(H) feet. The reason I use a rather small plastic box as reaction tank, is to make the test env more tougher.
2) Malodor source is: 5 fish (3 pounds) and two pounds cabbage. I don’t owe a 3KW growroom . So I can just use other materials to simulate weed’s odor smell. Rotten fish and cabbage are emit same materials like the weeds’. The materials are Piperidine, Pyridine and Pyrrole. Actually, Marijuana’s skunk smell is very similar with rotten cabbage. The reason is: both of them contain same chemical materials – piperidine, pyridine and pyrrole. These 5 fish and 2 pound cabbage were put into a glass jar and exposing under sunlight for 8 hours and then let them rotten for 10 days. You can image how skunk they are. Based on RedPlate testing method (detail referred to #3section), the odor concentration is around 2~5ppm. For a marijuana odor concentration, it will never up to 0.5ppm. Normally 0.05ppm is very sensitive for human beings. When piperidine concentration is up to 5ppm, it will be very danger for people (you will go into a coma under the odor for 10~30sec).
3) Testing Method is called Red Plate method; A white soft pinewood plate oozing with Hydrochloric Acid. This white plate will become red when it met piperidine/pyridine/pyrrole air. More high concentration piperidine/pyridine/pyrrole, few time from white to red. There are 2 timers for evaluating odor remove performance; Timer#1 is the time for original odor source air’s Red Plate testing time, and Timer#2 is the time for exhausting air(via Misting system) Red Plate testing time. The #1 timer is 5~10 second, and #2 timer is 30 minutes (the white plate is still white). So, it prove the Misting Solution is very efficient for Piperidine odor remove.
4) Fan selection: Because it don’t need high static air pressure, we just install a normal vent fan as entire system’s ventilation fan. In my test, an adjustable fan was adopted (max 1000cfm, min 200cfm). If I want to air move slowly (take more time in the reaction tank), a smaller cfm was selected. It make whole world more easier.
Testing - Cooling:
A Canadian team give a detail misting/water Evaporative Cooling Theory, Design , construction and testing results. You can get more info from their websites.
Residential Evaporative Cooling - Project Testing
Results show that an approximate cooling rate of 7 degrees with an increase in relative humidity of 61%. Overall temperature and humidity change in a small room (approximate room volume 882 ft3) was 5~7 degrees cooling and 60~70% relative humidity. This was measured after the device was let run for approximately 50 minutes, increasing this time will lead to an overall increase in humidity and a decrease in temperature.
My testing Results (Section Conclusion)
1) Odor Control: Nearly 100%Odor Erasing (2PPM IN vs 0.00PPM OUT)
2) Cooling Testing: 5 Degree fall for a small room volume (882ft3)
3) Humidity Control: Keep Hum around 60~70%.
Finally, I will represent my design concept figures and testing pictures as end of this thread. The final product is still under Engineering Testing period, so it should be posted on next thread. Thanks!
