What is a water treatment system?

Water treatment systems are used to improve the quality of the water in a household, business, restaurant or elsewhere. If a municipality’s water treatment system is not sufficient, or if a consumer is relying on water from a well source, then a home water treatment system becomes a viable option for cleaner, safer water. One example of this is softening hard water, which involves removing harmful contaminants or filtering out sediment or other particles. This allows previously unsuitable water to become drinkable and fit for household chores and other daily activities. Other water treatment systems remove unwanted chemicals from water.

How does water treatment work?

There are a variety of household water treatment systems that work in different ways. Water softeners remove magnesium and calcium in order to soften water. Reverse osmosis systems uses a semipermeable membrane to remove large particles from water. Other filtration systems can target specific problem areas, like high sediment or a chlorine taste, and focus on removing the offending substances. No matter how they work, all water treatment systems have the same aim of producing high-quality water for consumers and their families.

How to choose a water treatment system

1. Decide what contaminants to target

Water treatment systems remove a variety of different contaminants from water. The specific contaminants present in your water will help determine which type of water treatment system you want to buy.

  • Bacteria: Bacteria often lives in well water or other untreated water. Water treatment systems with UV radiation, distillation or reverse osmosis disinfection methods kill the bacteria that infect water and might make drinkers sick.
  • Minerals: Large concentrations of minerals result in hard water. Water softeners that use an ion-exchange resin are the natural solutions to hard water, though you can also rely on water treatment systems using active carbon filters, reverse osmosis, filtration and distillation.
  • Multi-contaminant removal: Some of the contaminants removed by water treatment systems include heavy metals from construction projects or damaged pipes that cause water to taste metallic, sediment that has gotten into a water supply through construction work and makes water appear muddy and brown; and chlorine added by public water companies to disinfect water sources, which gives water a strong chemical taste.

2. Compare home system options

Water treatment systems remove contaminants from your water as it flows into your house or as you use it.

  • Point of entry systems: Point of entry water treatment systems are able to treat all of the water entering a home or business and are installed after a water meter or storage tank. This ensures that all water used within the house, whether it comes from a faucet, showerhead or laundry machine, has been treated. Point of entry systems are also known as whole house water treatment systems.
  • Point of use systems: These water treatment systems are used where people directly access the water, like a kitchen sink or a showerhead.
  • Multi-system installations: Multi-system installations allow for several different types of water treatment, such as treating hardness with water softeners and removing pollutants via reverse osmosis.

3. Determine the source of your water

Where your water comes from will determine what sort of treatment it must undergo in order to be suitable for everyday use. Water treatment systems can treat water coming from a range of different sources.

  • Groundwater and water from lakes and rivers: Most water coming through the tap in your home originates underground or from a freshwater body. This common type of water is used for drinking and bathing in homes and businesses all over the United States. It is possible that this water has high levels of particulate matter or is overly chlorinated.
  • Brackish water: Brackish water is water that is part saltwater and part freshwater, which is often collected in estuaries. Brackish water can be collected and treated by water treatment companies to desalinate (using reverse osmosis). Then it can be used for irrigation or watering gardens and lawns.
  • Surface water: There are water treatment systems companies that specialize in treating surface water, which is collected rainwater or water at the top of a natural body of water. These companies collect the fresh surface water and use treatment to remove algae, bacteria and solids from the water in order to make it safe to drink or bathe with.

4. Choose if you want to be eco-friendly

All water softeners do have wastewater that can be hazardous. In this sense, no water treatment system is 100 percent eco-friendly. Still, there are options for consumers looking to reduce their impact on the environment.

  • Green filtration companies: There are some water filtration companies that filter water with the environment in mind, and they only use green materials and products.
  • Eco-friendly options: Some water treatment systems companies offer customers eco-friendly products and services, like salt-free treatments, which use significantly less water to filter water than a traditional salt-based system.
  • Traditional water treatment systems companies: Many water treatment systems companies use traditional technology and products, and they are not particularly focused on environmental-friendliness.

5. Understand maintenance requirements

Performing proper maintenance on your water treatment system is a must if you want it to continue working, and it’s always wise to follow best practices.

  • No maintenance required: Some water treatment companies handle all maintenance for water treatment systems, including installation and regular check-ins and updates.
  • Minimal maintenance: There are some water treatment systems that require minimal maintenance from customers, like checking filters to see if they are clogged or dirty or watching monitors on filters that change color when they are ready to be replaced.
  • Customer maintained: Some water treatment systems require complete maintenance by the customer. This might involve tasks like replacing filters regularly or adding salt to water softeners.

Types of water treatment

The type of water treatment system you need will depend largely on what you want to achieve. Certain methods only remove physical impurities, others chemical impurities, while some remove both. The most common types of water treatment systems include:

  • Water softeners
    Water softeners take hard water and make it soft. Hard water has a high level of minerals making it unpleasant to drink or use. Water softeners remove certain minerals, including calcium and magnesium, to soften the water.
  • Water conditioners
    The term “water conditioners” applies to a wide variety of products that remove impurities from water. They do not, like water softeners, specifically reduce water hardness. Some remove chlorine, improving the flavor of water.
  • Activated carbon filters
    Activated carbon filters use beds of activated carbon to remove contaminants from water. This is done through the process of chemical absorption, where contaminants are trapped within the porous structure of the carbon filter. Carbon filters remove chlorine, taste and odor from water. If you feel that your home’s water has too strong of a taste that you would like to neutralize, a water treatment system with a carbon filter might be a good choice.
  • UV filters (Ultraviolet)
    Companies that use UV technology utilize UV rays to disinfect water and kill bacteria. If your water source is a well or another source that might host harmful bacteria, then a UV filter water treatment system will serve you well.
  • Distillation
    Distillation is not as commonly used as it was in the past, but it does have a long history and is an effective method of treating water. The water is boiled and, as the water turns into steam, it is collected, leaving contaminants behind.
  • Reverse osmosis
    Some water treatment systems rely on reverse osmosis, a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by normal household water pressure pushing tap water through a semipermeable membrane. A reverse osmosis system is a good choice if you want to remove particulate matter from your water. It also makes water taste more neutral.
