WHAT ARE IRON BACTERIA?
Iron-oxidizing bacteria are chemotropic bacteria that generate energy by oxidising ferrous iron in solution. They have been shown to thrive and multiply in waters with iron concentrations as low as 0.1 mg/L. To carry out the oxidation, however, at least 0.3 ppm of dissolved oxygen is required.
SIGNS OF IRON BACTERIA IN WATER
Because oxides are rust-coloured, they are easy to identify in water that should otherwise be clear.The iron oxides will continue to degrade over time, releasing a slimy substance into the water. This substance might be brownish or reddish in colour. If you observe clumpy or slimy deposits in your water, it's extremely probable that these deposits were created by the presence of iron bacteria.
In toilet tanks, iron bacteria deposits are very frequent. In many situations, these deposits may appear as a slimy coating along the tank's walls, which is rather easy to remove.If these bacteria have been in the water for an extended amount of time, the deposits may float in the water, necessitating the disposal of the entire tank. When you observe an oily sheen on the surface of the water, stir it around with a stick. If the oily quality of the water breaks apart, iron bacteria are most likely to blame.
Some of the more frequent tastes and scents you'll experience when iron bacteria are present in your water are as follows:
1- A rotten egg odour
2- An odour like sewage
3- A musty odour
4- A somewhat pleasant odour
5- A flavour that is similar to gasoline or rotting vegetables
IRON BACTERIA TREATMENT
Iron bacteria and sulphur have the ability to generate micro-zones of high acidity as well as concentrations of extremely corrosive ions, which can be very destructive to plumbing equipment. Keep in mind that corrosion is often worse in regions of the plumbing that contain stagnant or still water. These corrosion difficulties can be reduced by installing an iron bacteria cleaning system, which will cleanse the water.
The three basic steps of an efficient iron treatment are as follows:
Injection of a disinfectant: The initial step in therapy is to inject a disinfectant into the water. Chlorine and ozone are two basic disinfectants that can be used. If you choose ozone as your disinfectant, you might install an ozone iron filter, which is an all-in-one device that oxidises iron before capturing oxidised pollutants. The third and last disinfection choice is hydrogen peroxide, which destroys iron bacteria quickly. The primary disadvantage of this technique is that more than 100ppm of hydrogen peroxide must be kept in the water.
Retaining (time to kill bacteria): After user has completed the disinfection step, it's time to go on to the retention stage, which includes the usage of a retention tank. It's critical to remember that the chlorine or ozone user employ takes time to eliminate the iron bacteria. During this step, the disinfectant and water will be deposited in a retention tank. The size of the tank user select is determined by the flow-rate requirement.
Filtration (removes oxidised metals and bacteria): The third and last stage of iron bacteria treatment is filtering, which is intended to remove all oxidised metals and bacteria from the water. This phase consists of three distinct stages:
1- Preparation or oxidation
While iron bacteria isn't inherently damaging to a person's health, it can make water taste bad and emit foul aromas that may be tough to deal with. Iron bacteria is very corrosive and may cause substantial damage to your equipment and the plumbing in your industrial environment, which is why it's critical to discover and eliminate iron bacteria as soon as possible. Using the three methods outlined above, you should be able to cleanse the water before effectively eliminating any iron pollutants. Once the impurities have been completely eliminated, consider trying to avoid further iron bacterial infection, which mostly entails cleaning the water on a regular basis.
