Comment fonctionnent les appareils de purification d'eau ?

Water purification devices come in many forms, with different advantages and disadvantages. Below, we’ll discuss some of the most common options. We will also discuss how reverse osmosis works. Reverse osmosis is an advanced method that has several advantages over other types of purification systems.

Filtration systems kill bacteria.

There are several ways to disinfect water, but nothing beats a filter system for eliminating bacteria. While chlorine, iodine, and boiling all kill some bacteria, none can eliminate all of them. In addition, these methods also require an energy source and are not practical when only disinfecting a small amount of water. To prevent bacteria and viruses from entering your home, it is best to use a filter system that eliminates these microorganisms.

Filtration systems control impurities

There are many kinds of filtration systems. They include pitchers, activated carbon charcoal filters, ultraviolet light units, reverse osmosis, and other processes to remove impurities from water. Water treatment systems range from home filter systems to large municipal water treatment plants, and some appliances even have a water filtration feature built-in. The water filter system you choose will depend on the number of suspended solids you want to remove.

Mechanical filtration

Water purification devices that use mechanical filtration remove sediment, dirt, and other particles from the water. Mechanical filters can be as simple as basic mesh or sophisticated systems to remove larger debris and pathogenic organisms. The size of particles removed by a mechanical filter can vary based on the type, but larger particles are removed faster with sand media filters. Other filters use ceramic or fiber filter media with smaller pore sizes and are slower, requiring frequent replacement.

Distillation is the oldest method of water purification.

Distillation is one of the oldest methods of water purification, and it removes more than just ions, but some contaminants are still left behind. Distillation can remove virtually all chemicals, minerals, and bacteria from drinking water, although it does not remove all contaminants. Some volatile organics and bacteria will evaporate when the water is distilled, so pre-treatment filtering is essential.

Reverse osmosis is the most powerful method of water purification.

Reverse osmosis is a water filtration technology that is highly effective at removing larger particles. This type of purification method is used by many industries, including food and beverage, pharmaceuticals, and semiconductors. This water purification method is also effective at removing sediments, bacteria, and even lead particulates, and it can remove contaminants that other methods fail to remove. It uses high-pressure pumps and does not require thermal energy or power.

Membrane filters

Water utilities are turning to membrane processes for advanced wastewater treatment and potable water production, thanks to the increasing cost of conventional treatments and scarcity of freshwater resources. As a result, membrane processes have become more popular and are now available in many configurations and materials. They effectively remove different types of contaminants and have numerous benefits, including advanced filtration of wastewater and desalination. 

UV light

Most people are interested in finding out if UV light can work with water purification devices. If you’ve recently taken a water test and noticed E. coli or other coliform bacteria, you may want to consider getting a UV light water filter. But before you do anything, you need to have a good idea of whether or not the water quality in your area is safe. If you’re not sure, you can have the water tested at any laboratory.
