All About Iron In Your Water

  1. 1. All About Iron In Your Water and Why You Should Remove It Water Filters Express By Water Filters
  2. 2. Water supplies usually carry a small amount of iron, and in small quantities, it rarely presents a problem. There are, however, times when large amounts of iron are present and this can become problematic. Although iron as such is not harmful to humans, it can on occasion make water unusable for household use. In such cases, it is important to use an iron water filter to remove the excess iron.
  3. 3. How does Iron get into Water Supplies?
  4. 4. The water used in: Domestic Domestic Commercial Commercial Industrial Industrial settings is derived from either ground or surface water sources. As a rule, surface water contains very little or no iron at all.
  5. 5. As it stands, however, the majority of the water we use comes from ground water wells, ranging in depths between under 100 feet up to thousands of feet. Water continually circles through what is known as the hydrologic cycle. Essentially, it falls onto the ground, seeps into the ground or enters rivers and oceans, evaporates from there, forms clouds, then falls again in the shape of rain, hail or snow.
  6. 6. The Hydrologic Cycle
  7. 7. The water that seeps into the ground travels through the various layers - or strata – of the ground and eventually collects in so-called saturation zones. Ground water wells are drilled into these zones to collect the water from there. As the water travels through the ground's strata, it dissolves and collects minerals from within the soil. These minerals include calcium, iron, magnesium and manganese, to name but a few of them.
  8. 8. Because the soil varies from location to location, so does the water found in wells. One of the most troublesome, unstable variables resulting from particular regional geology is iron content. As the water dissolves iron from iron ore in the ground, it creates what is known as ferrous bicarbonate. Because this cannot be seen, it is called clear water iron.
  9. 9. Iron will always try to get back into its natural state and will precipitate out of the solution into a solid state. These particles are known as ferric hydroxide and will turn the water red. Consequently, this is known as red water iron. How quickly this change will occur depends on the temperature, pressure and the pH of the water. The higher the pH factor, the quicker red water iron will form.
  11. 11. Iron can have numerous effects from staining fixtures and appliances like kettles or water softeners and surfaces, with stains ranging in color from yellow through red into brown, through creating foul odors or an unpalatable, metallic taste. It can also clog pipes and heat exchangers.
  12. 12. None of these effects are actually hazardous to humans or the environment, but they can result in large amounts of money being spent and the use of toxic cleaners to remove them, which will ultimately affect the environment.
  13. 13. It is therefore typically more practical and cost effective to use an iron water filter and remove the iron before using the water, rather than trying to deal with the effects of clear or red water iron in your home’s plumbing system.
  14. 14. What are the TYPES OF IRON
  15. 15. To successfully remove iron from water with the help of an iron water filter, it is first of all essential to determine which type of iron is actually contained within the water.
  16. 16. This can be done by testing water, and the tests should include: testing for pH total hardness alkalinity total dissolved solids manganese, tannins, iron and also iron bacteria
  17. 17. A misdiagnosis and use of the wrong type of iron present in the water will typically result in any iron removal filter working only for a short period of time, after which it will simply become fouled with the iron it is not actually removing.
  18. 18. The majority of iron water filter processes are designed to effectively reduce clear or red water iron. There are, however, other iron types, which will cause the same kind of symptoms typical for iron contamination.
  19. 19. Other IRON TYPES
  20. 20. • This can only be found in our municipal water supplies. In order to keep a clear water state, a sequestering to the water supply. Sequestered Iron agent is added • The iron is encapsulated by this agent, preventing it from becoming ferric and creating the red water state. • Unfortunately, this agent often breaks down before the water enters homes, somewhat defeating its purpose, and in addition, this agent also reduces the effectiveness of an iron water filter.
  21. 21. • This type has formed compounds with other organics present in the water. • These compounds do not react to typical Home Iron iron-reducing methods and usually pass straight through an iron water filter. • If this type is present, other technologies have to be utilized to remove the organics in order for an iron effectively. water filter to work
  22. 22. • One of the most frequently misdiagnosed problems, iron-bacteria can actually be increased by using some iron water filter systems. Iron Bacteria • This effectively makes matters worse for the consumer. Consisting of life organisms, the bacteria needs food (iron) and oxygen to grow.
  23. 23. It is not harmful with regards to human or animal consumption, but can clog pipes, pumps and water treatment systems. As such, it may produce symptoms like: •loss of pressure, •odors, •foul tastes and •staining The best method of controlling these bacteria is through chlorination, which should be applied upstream from any iron removal equipment.
  24. 24. How to REDUCE IRON
  25. 25. Once the iron type contained within the water supply has been identified and the characteristics of the water are understood, reducing iron can be fairly simple. Two basic technologies are used to reduce iron, namely:
  26. 26. Small amounts of ferrous iron can usually be successfully removed with the ion exchange process involved in the use of water softeners. Ion Exchange Due to the fact that water supplies and applications vary, which will have an effect on how successful treatment with ion exchange equipment is, it is advisable to consult a local water treatment professional in order to determine whether this approach will be suitable for your particular situation.
  27. 27. This approach is typically employed if quantities of iron exceed the above stated levels, or if the pH factor of the water is greater than eight, when it may be employed even if iron levels are comparatively low. In this process, oxygen is introduced into the water to convert the ferrous bicarbonate (clear water iron) into ferric Oxidation/ Iron Water Filter hydroxide (red water iron). After the iron has thus been converted into solid iron particles, an iron water filter will serve to remove the iron from the water.
  28. 28. It is typical today for an automatic backwashing iron water filter to be used to filter out the solid, or precipitated, iron particles. Regular back-washing is important in order to prevent the iron filter bed from becoming fouled.
  29. 29. Most manufacturers suggest that back-washing should be performed every three days, although very high iron content may make it necessary to perform the process more frequently. Essentially, back-wash intervals depend on the water supply and the iron content within it, the applications used and the amount of water usage. Ultimately, it is always best to consult an expert dealing with water treatment in order to determine which type of technology will be most suitable for iron reduction in any given area or circumstances.
  30. 30. The SUMMARY
  31. 31. To sum up, iron is present in water supplies in most cases. Although the presence of iron in water is not harmful to humans, animals or the environment as such, it can cause a list of unpleasant symptoms: staining everything the water touches clogging up and fouling water-using equipment, pipes, etc cause unpleasant odors and metallic tastes
  32. 32. As well as being unpleasant, these symptoms may also create unnecessary expenses in order to clear up some of the more physical symptoms, such as staining and clogging of pipes and it may also result in the environment being harmed through the use of toxic detergents.
  33. 33. Iron therefore needs to be reduced in order to prevent these symptoms from occurring. Before it can be removed from the water supply, however, it is necessary to determine which type of iron and how much of it is actually present. The type and quantity of iron present will then assist in determining which type of technology should be employed in order to successfully remove it. The most commonly used technologies include ion exchange through water softeners, which is usually employed in cases of low contamination, and oxidation combined with filtration in areas with high contamination.
  34. 34. As a rule, it is considered to be of great advantage to consult a professional water treatment expert in order to determine the most efficient, most effective method of iron reduction for a particular area and specific situations. Reverse Osmosis Undersink Countertop Whole House
