Guest guest Posted July 1, 2010 Report Share Posted July 1, 2010 Hello Agnes, Chlorine dioxide is an excellent water purifier. In an effort to keep the concentrations down to a safe level, you would probably want to use 15% sodium chlorite and 16.5% hydrochloric acid. In general, a 14000 gallon tank full of water would need about 1 liter of each. You would mix 1 liter of 15% sodium chlorite and 1 liter of 16.5% HCl, then add that to the water tank. That will give you 14000 gallons of water with about 1.75 PPM free chlorine dioxide in it. At these higher chemical concentrations the reaction is more aggressive so caution should be used when mixing, and avoid the fumes. There may need to be some adjustment to account for specific conditions, but these concentrations usually work very well at keeping things from growing in the tank. The advantage to using chlorine dioxide is that no chlorination by products are produced. The plants will be getting water that is purer than that in which bleach was used to disinfect. In addition, as soon as the chlorine dioxide water is exposed to UV light, the chlorine dioxide will be driven off and the plants will be getting pure water. The down side is that sodium chlorite + HCl + the labor of mixing it and adding it end up being more expensive than simply pouring bleach into the water, and there is the added step of activation. Public water systems use chlorine because it is cheap. Industry uses chlorine dioxide because it is more effective. The pass the extra cost on to the customer.

Guest guest Posted July 1, 2010 Report Share Posted July 1, 2010 Trans, Interesting. I am in , Tx and last Tuesday, i seem to have smelled oil in the air after a rainfall the night before. Am now wondering if the oil rain in Louisiana got here as well. But now it has been raining since Tuesday night and is still raining until now, but no oil smell. There was a post that a scientist said that this spill will eventually be in all oceans in 18 months. I watched the Lindsey YouTube and he said the spill is 4 million barrels a day, Gulp! Another scientist said It will affect our oxygen supply (dangerous level is 12% and below, we are not too far from it, i forgot 15-25%?). It will affect the atmosphere, rain, water supply, vegetation and animals. It is a chain reaction from the pollution in the atmosphere. Aren't they so clever? Of course it will affect the air we breathe. I just now remember when W was exiting, some W administration people were reported to have bought up all the emergency supplies of food, etc. and the manufacturers said it was not delivered to relief agencies but were for personal use? HHHmmmm, i wonder why. Are any of the above claims true? Aetheists, please don't proceed to read below. There is no where to turn to but PRAYER! Those who believe in God no matter what religious belief you have, please PRAY (on your knees, if possible) and bombard heaven to help us, the innocent victims.

Guest guest Posted July 1, 2010 Report Share Posted July 1, 2010 Hello Tanstaafl, It is interesting you should ask... You aren't the only one asking that question. Chlorine dioxide is used in drilling to eliminate hydrogen sulfide and other toxic gases. It does a great job of doing that, but it does not remove oil from water. We have been doing some tests on this and it seems that if you set up a sand filter to do a pre-filter, whatever is left will be pretty much be removed with chlorine dioxide. The process is a little involved and basically starts with the sand filter, goes to a holding area where flocculants are added, then goes through aeration, and the final stage is disinfection using chlorine dioxide. Chlorine dioxide is also very good at removing hazardous odors from the air. If someone is noticing foul odors inside their house as a result of the fumes being blown inland, it was be best to vacate the area and find fresh air. However, if the odor is only at a " nuisance " level and has not reached a concentration where it is hazardous, you could mix up some sodium chlorite in water and fog the area to get it under control. This would be similar to fogging a chicken coop. Obviously, air quality testing would be needed to make sure things are not getting out of control. A potential problem with this is that you could create a safe area inside your house, and have a hazardous build up outside. When you step outside, you may die. With air currents freely flowing, the usual case is the opposite. The house provides a stagnant area where concentrations can build up. Many of these chemicals have an odor threshold that is below their toxic threshold, so there is some warning before you get into trouble, but odor thresholds vary between people and it is best to test the air quality with a calibrated device. If you have ever been down wind of an oil refinery you will know that there are a lot of odors that are unpleasant, but are not supposed to be at a level that is harmful. On a side note... Chlorine dioxide has been successfully used to control algae blooms. When the oil eating bacteria get into full swing, they will deplete the water of oxygen and form an algae bloom. It may be possible to use chlorine dioxide to kill off the algae and then normal wave action and currents may be able to re-oxygenate the water. I sent this information to the clean up efforts as a possible suggestion for clean up. While it has been used in holding ponds, I don't think it has ever been attempted in open water. Oh well, they were asking for ideas and I just threw one out.
