There is no one size fits all approach to water filtration because the quality of water can be very different depending on where you live. Many people install one or more filtration systems to deal with specific water quality issues that affect their homes. The best approach is to start with a laboratory water test to discover which contaminants are present. The results of this water test will help you to make informed decisions and a local water treatment specialist can install those systems for you. In this article, we will take a closer look at three effective water filtration and purification systems.
1. Reverse Osmosis (RO) Filtration
This is a mechanical filtration system. The incoming water is placed under pressure and then forced through a semi-permeable membrane. The pores of the membrane are tiny, water molecules can pass through, but many other contaminants are removed. This process takes time, for this reason the filtered water is held in a storage tank. The most common format for this system is a point-of-use (POU) setup at a single tap. This is usually located at the kitchen sink for convenient access to clean water for drinking and cooking. The RO system usually has a pre-filter to remove sediment which protects the membrane from larger particulates that can cause damage. A granular activated carbon (GAC) is typically installed to add some final polish to the water. RO filtration can remove a wide variety of contaminants, including chlorine, fluoride, nitrates, lead, iron, heavy metals and more.
2. Ultraviolet (UV) Sterilization
Light in the UV range is at the same spectrum as sunlight, which is highly effective at disrupting the DNA of microorganisms. The main threat from bacteria, viruses and other harmful pathogens is their ability to replicate in the human body and on surfaces. This is why UV lamps are now used widely for disinfection at hospitals, the dentist office and in water purification. This is a simple system that relies on a UV bulb to treat the water that passes by and the bulbs are relatively inexpensive. Some of the microbial threats that UV light can remove, include Giardia, E.coli, Salmonella, Cryptosporidium, Typhoid and many more. UV light is 99.99% effective at removing any microorganisms and it adds no chemicals to your drinking water.
3. Water Filters
There are many types of water filters to deal with a wide variety of water quality issues, but they all work on the same principle. The incoming water is passed through a filtration media that is housed in a cartridge or media tank. Filtration can improve the aesthetic qualities of water, such as taste, odor and appearance. More elaborate filters can remove sediment, iron and other particulates that can lower the water quality.
You may need one or more filtration systems depending on the specific water quality issues you need to address. A water test is a great way to start, but a laboratory test will be more accurate than a testing kit from your local home improvement store. Contact your local water quality specialist to improve your water quality today.
