Drinking untreated water poses a significant health risk. This water may contain harmful microorganisms that can cause serious illness. It is therefore crucial to properly disinfect the water in order to minimize the risks associated with its use.
The risks associated with untreated water are significant and can have serious health consequences. Water that has not been properly disinfected can contain harmful microorganisms such as E. coli bacteria, enterococci, and other pathogens that can cause illnesses ranging from mild gastrointestinal problems to serious illnesses such as cholera or dysentery. Long-term exposure to contaminated water can lead to chronic health problems, especially in vulnerable populations such as children, the elderly or those with weakened immune systems. Disinfection of drinking water is therefore a necessary step to prevent these risks.
Disinfection of drinking water is a key step in ensuring a safe and healthy water source for households and industry. Commonly used disinfection methods include the use of chemicals such as chlorine or chloramine, as well as physical methods such as ultraviolet (UV) radiation. Chlorine is the most commonly used disinfectant due to its ability to effectively kill a wide range of microorganisms, including bacteria, viruses and parasites. UV radiation, on the other hand, offers an eco-friendly alternative that uses no chemicals and leaves no by-products. Each method has its advantages and disadvantages, and the choice of a particular approach depends on the quality and source of the water.
The advantage of chlorination is its long-term effectiveness. Chlorine persists in water for a relatively long time. This residual effect ensures that the water remains disinfected even when it is transported through the distribution network.
But it is important not to forget the formation of by-products: Chlorine can react with organic substances in the water to form by-products such as trihalomethanes (THMs) and haloacetic acids (HAAs), which can be carcinogenic and pose a health risk with long-term exposure. Some people may find chlorinated water unpleasant due to the characteristic taste and smell of chlorine, which can affect its acceptability. And last but not least, it is very little effective against some parasites such as Cryptosporidium and Giardia
By using UV disinfection, there are no chemical by-products, so there are no harmful by-products, making it an eco-friendly and healthy choice.
It is a very effective disinfectant against a wide range of pathogens, including bacteria, viruses and parasites.
UV disinfection does not change the taste or smell of water, which is beneficial for consumers who prefer water without the presence of chemicals.
