In marine applications, electrochlorination can be used to treat drinking water by filtering out salt and adding chlorine. Electrochlorination (ref. Cathodic Marine) is the process of using electrolysis facilitated by a low voltage DC current to produce sodium hypochlorite and hydrogen gas. Dehydrogenization is then used to remove excess hydrogen gas and the final solution is then considered to be safe drinking water. Since this process is so simple, it is widely used to produce drinking water for many cities around the world. This is also the process that is responsible for the chlorine that consumers today find in their water. This article will explain how this process is used today in marine engineering services today.
Treating Sea Water
Water that comes from the ocean is generally considered unsafe for drinking since it has too much salt and other microorganisms. While in the past this water was difficult to treat, today it can be easily processed through electrochemical treatment. After being exposed to electricity, seawater will quickly have its salt filtered out along with other microorganisms. During this process, the water will become safer to drink since it will still contain chlorine and will therefore be resistant to possible contamination. This technology enables cities to extract water directly from the ocean rather than having to use traditional freshwater sources. Especially in areas were water is scarce, this can be very helpful for saving costs on water.
Treating Fresh Water
Like seawater, freshwater must be treated as well in order for it to be safe to drink. Fresh water is often treated using electrochlorination since it is a quick way of removing microorganisms and adding chlorine to water. In this way, the water becomes safer to drink throughout the city even when it is left stagnant. In the West, water treated using this technology has enabled water sources to be much safer over the last 100 years. In fact, this is one of the main reasons why life expectancies today are so much longer that they were the past. Treated water is safer for drinking and it prevents problems like typhoid fever and dysentery.
Usage in Swimming Pools
Individuals with swimming pools can use electrochemical treatments to prevent microorganisms from taking over the pool. These processes will allow pools to be safer as well since the water won’t be contaminated and make others sick. In all, this chlorination process makes the lives of pool owners easier while making them safer at the same time. This makes it so that pool water does not have to be replaced as often as otherwise would have to. In former times, pool water would have to be replaced very frequently in order to prevent microrganisms organisms from accumulating. Today, these problems are virtually nonexistent thanks to electrochemical treatment technology.
