WorldExecutivesDigest.com | Understanding the Different Types of Water Filtration System for Your Home | The human body is composed of up to 60% water. It is therefore important that you keep hydrated at all times with clean water. However, getting a supply of pure drinking water can be challenging for a lot of people.
While municipalities are tasked to treat the community’s water supply to be safe to drink, treatment chemicals such as chlorine can leave the water tasting unpleasant. Likewise, your home may be supplied by hard water, which causes limescale formation that can damage pipes and appliances such as washing machines and water heaters. Fortunately, you can solve these water issues by installing a water filter system in your home.
How Water Filtration Systems Work
Water filters are used to remove impurities from your home’s water supply. The main purpose of a water filter system is to soften and produce better-tasting drinking water. There are many filter systems that you can choose from which uses these five types of filtration processes.
Mechanical. Mechanical filtration uses a sieve that physically separates dissolved particles as water flows through it. This filtration process uses a ceramic filter with different micron ratings.
- A filter with a 5-micron rating can remove most particles that the naked eyes can see.
- A filter with a 1-micron rating can separate microscopic particles.
- A 0.5-micron rating can remove pathogens and parasites carrying cysts that make people sick.
Absorption. Absorption filtration involves the use of carbon to capture dissolved water contaminants. Carbon effectively absorbs contaminants because it has many internal surface areas that can trap unwanted chemical compounds such as chlorine in the water.
Sequestration. Sequestration filtration uses chemicals to confiscate chemical compounds that tend to produce limescale and corrode water pipes. Food grade polyphosphate binds with calcium and magnesium, making them unable to form scales or corrode surfaces they contact. However, sequestration only inhibits the action of these minerals and does not soften the water.
Ion Exchange. Water is considered hard water if it has high alkalinity levels. Hard water can damage appliances such as your coffee machine and washers. You can “soften” your home’s water supply by using an ion exchange filter.
Ion exchange uses a filter that is made up of sodium or hydrogen ions. When hard water passes through this filter, the magnesium and calcium ions dissolved in water will exchange with the sodium or hydrogen ions. The water that passed through this filter will then be free of hard minerals. However, filters that use sodium ions are not suitable for producing drinking water and must be used for filtering water to be used by appliances only. A hydrogen-based ion exchange filter is ideal for drinking water.
Reverse Osmosis. Reverse osmosis uses pressure to force water through a semipermeable membrane that separates dissolved inorganic compounds from pure water. The membrane used in this type of filtration has a rating of 0.0001 microns which removes 95 to 99% of dissolved solids in drinking water.
How to Choose Water Filters for Your Home
Each type of filtration process is limited in its effectiveness in removing dissolved compounds from your water supply. When choosing a filter system for your home, it is important to determine the type of filtration that the filter system will use. It is also best to determine the existing quality of your water to know what type of filtration process you are going to need. For example, if you are already receiving a good supply of “soft” water, you will need a system with mechanical and absorption filters.
Knowing how each type of filtration system works will help you decide what water filter system to purchase for your home.
