TIP: UV is not Always the Best Way to Treat Water!

300px-SOHO_EIT_ultraviolet_corona_imageCustomers often ask us about  UV vs Chlorine treatment. We always ask first;  What are you trying to fix in the water? More precisely  what bacteria do you have present in the water? Some bacterium like Iron Bacteria, do not always respond to UV. Sulfur reducing bacteria, does not respond to UV. The only UV light controllable bacteria that we normally would recommend are E-coli and Coliform. We never recommend that as a solution if there are measurable amounts of iron, sulfur, manganese or high hardness or limestone levels as these substances can render UV as useless. One other problem is that the term Coliform can describe many different kinds of bacteria. For example, Iron bacteria is Coliform but Fecal Coliform is not Iron bacteria(and it is very bad for you health). Fecal Coliform is especially dangerous to senior citizens and/or children in the home. It also may affect your pets.

UV must be used only under specific and strict water conditions. The water must be low in hardness and virtually sediment must be removed for a UV light to safely remove harmful bacterium. The water being treated should also be free of iron, sulfur and manganese. Otherwise a particle like iron, manganese, magnesium, calcium, etc may be penetrated by a bacterium found in the water and ride through the UV using the particles as a shield from the UV light. There is no way to know if your water is contaminated with E-coli or Coliform without proper testing. Please call in to one of our friendly tech’s who can help you determine what you need to do.

Naturally Soft water is not common in well water, so you should consider options when water has been diagnosed with E-coli and/or Coliform. The best option is a chlorination system that can be monitored. The benefit of chlorinating a private home well is that water is stored with chlorine in a retention tank to ensure that the water is properly disinfected.Remember too that  Hydrogen peroxide is almost never better than chlorine. Chlorine is very inexpensive and Hydrogen Peroxide is very expensive. Most companies that recommend peroxide are just selling an over priced system. Many water treatment systems sold today can be harmed by peroxide and require expensive repair calls . We always want your water treatment equipment to last and for you to save money. There are times that we do recommend a UV to correct ecoli or coliform, but it is fairly rare because of other contaminants or substances that are present in the water supply being treated. We always take the time and explain everything to you so that you end up with the best equipment, the right equipment and the most affordable equipment.
