how effective is U/V light for treating well water bacteria?
357486
we have a u/v light they said it was good cuz it shocks the water and kills the bacteria before it get to us....i take it they also shocked your well with chlorine...DONOT wash colored clothes for a few days!!!it will ruin them...they told my mom it was alright to wash clothes....she ruined my new outfit...i was fit to be tied(lol)....but it is very effective and does a good job...when it needs to be changed...it will automatically beep....don't Wait too long to call them(i think you have 1 week )

it's totally depends on the type of the bacteria!\n1)sterilization:fungi is so sentitive to this condition.but if the bacteria is the kind that produce endospore then this method is not useful\n2)pasteurization:kills all the bacterias except the one couses Query\n3)filterization:useful for bacterias except Mycoplasma\n4)Rays like UV X and Gamma\n5)chemical Gases which are mutagenes like rays\n6)chemical liquids

I've learned that reinventing the well is not really the best solution.\n\nI've tried this solution and it works perfect for my need:\n\nhttp://www.codeproject.com/cs/miscctrl/csharpgridcontrol.asp

Able to be dissolved by water.

Saltwater will kill bacteria, but not as effectively as alcohol based mouthwashes.  Still, it's a cheap option, but you have to do it every half hour for a couple of days.

Try using a pro-biotic product. The bacteria in the product digests waste. They use this in commercial ponds for cleaning before restocking, and also in oil spills, because it can digest petrol. Ask your local house and garden supplies shop, or if you live near farms ask them.

These bacteria probably have the lux gene which codes for bioluminesence. A resonable mechanism that would cause this to arise is mutation. These lighted cells would probably have benefited some how from glowing in the dark. Some deep sea fishes have bacteria which code for this gene (Vibrio fischer) Which may have helped these fish find food in the dark waters. Thus those fishes without this gene would have died out because of natural selection. What you could do is put these fishes with the bacteria that glow in the dark in the same pool of dark water as the fishes without this gene. Then provide a limited food source so that not everyone could receive food and only the strongest would survive. If the fishes without this bacteria eventually died out but the others stayed alive, you have proven your hypothesis. If not, then failure willl be an obsticle to overcome.\n\nHope i was helpful

Using elodea (pond plant) in water (gives the elodea the water it needs for photosynthesis) with a small amount of sodium hydrogen carbonate added (gives the elodea the carbon dioxide it needs for photosynthesis) in a test tube, put it at different distances from a source of light. Then for a minute at each distance, count the amount of bubbles of oxygen being produced by the elodea in the test tube. This shows how the rate of photosynthesis is affected by the light intensity. Remember to use a perspex screen between the light source and test tube so that no warmth is passed from the light source to the elodea, affecting the results.\nI hope this makes some sense!!!\nBest wishes.

Do it in a laminar flow hood. Follow aseptic techniques.\nDepending on your use, you may suspend your bacterial culture in an appropriate medium.\n\nIf you dont have a laminar flow hood, do it the traditional way...\nwash your hands, then put alcohol.\nwork on a clean table - clean it with alcohol.\nlight an alcohol lamp in the area to clean air.\nopen your culture tube near the light.\ntransfer aseptically the bacterial culture to cuvette\n  - do it near light to ensure no contaminants from air\ncover the cuvetter near the light.

I suggest hydrogen peroxide 'bleach' because it is much less toxic than regular bleach, but it still destroys many pathogens.\n \n Also, 70% Isopropyl alcohol is a good disinfectant.

I have been using colloidal silver for years as a natural antibiotic/viral at 500ppm and I haven't turned blue like some idiots will tell you. It kills over 650 types of viruses, bacteria,yeasts,and fungi. I just used it on my nephew's pinkeye and it was gone in one day. You have to research it yourself and decide. Also look up olive leaf extract, grapefruit seed extract,and oreganocillin.

Two solutions that you will find in any home, tea and coffee. They should do the job nicely.\nThe longer you leave it in the fluid, the darker it will become, so check it often.

Depends on the bacteria.  Light can damage cells.  UV light is used to kill bacteria, and a single cell has very little defense to the sun's light, oppose to multicellular creatures.  On the otherhand there is more food in the light.  Especially for cyanobacter, who needs light to survive.  My guess is that there is a lot more bacteria in the dark, because their are alot more dark places.

bleach\namonia(dont mix with bleach)\nAlcohol(pocibly boose and beer)\nAnti bacterial soap\nSpit/dog slober(ensymes)\nurin(amonia(eewww nasty))\nhot water\nsomething involving a microvave toster or some other heating apliance\nsalt water\nor you could shoot them(aim carefully, bacteria is small)

I don't know what you're rinsing so it's hard to answer this question. \n\nIf you have 10,000 bacteria in a 1.0 mL sample and your first rinse removes 99% of them then you still have 100 left (more than enough to make someone sick if it's a nasty pathogen.) If you rinse again and remove another 99% then you're down to 1 bacteria per mL. Rinse a third time and you can reduce the count to 0.1 bacteria per mL. \n\nThe result is you've reduced your starting count by 6 logrithmic. That is an acceptable reduction from a food processing standpoint. \n\nThe numbers I gave are totally arbitrary since I don't have any specifics. Its possible that each rinse removes more (99.9) or less (90% or lower)bacteria.
