Water Sterilization

Knowing that the water we consume is sterilized gives peace of mind. The absence of bacteria and viruses in the water we use in the kitchen, shower and washing the dishes is very beneficial for our health. There are two common methods used for this purpose.

The first is to kill both bacteria and viruses using ultraviolet light.

Due to the risk of re-contamination during the water transfer, ultraviolet sterilization should be applied at the entrance of local water supply, or more precisely just before using water. Where water is to be transported over long distances, the full benefit cannot be achieved because the water may become contaminated again during transport. It is common to use u/v at the entrance of flats, at the exit of the water tank in places such as hotels, patisseries, restaurants.

In order for the ultraviolet device to be effective, a light with a capacity suitable for the flow rate of water must be used. In order for all bacteria and viruses in the water to die, the time they are exposed to ultraviolet light must be long enough.

It is beneficial to use a water softener before ultraviolet water in order to maintain the transparency of the cover containing ultraviolet light. Otherwise, the lime scale accumulating around the lamp cover does not allow ultraviolet light touch the bacteria and viruses.

The second common method is to kill bacteria by chlorination.

This method is mostly preferred in cases where water will be transferred to long distances, for example in municipal water reservoirs. Since chlorine travels together with water, it is an effective method against contamination that may occur on the way, for example in water pipes. In chlorination disinfection method, it is important to use sufficient amount of chlorine to kill bacteria and less than the level it would threaten human health. In order to use the right dose of chlorine, fully automatic dosage pumps are used.

The most important disadvantages of disinfection using chlorine are that some viruses are resistant to chlorine and chlorine is a chemical substance that should not be consumed by humans. In this method, it is recommended to use filters that remove the chlorine of the water just before use.
